ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXX2CrR//JCVInAQLTghAA0f+2V2wC6HVBfDhT1YmhbAkPF1KzgLbB h30fN6BtIe9mE3kR69uWgwPSzn4hTKEQXoC9m6S+XClTn6MKPrbCEYDZl4ZwIER8 XDamxJV+6oTG+GKtKpHFkC4WPJkLthEuD34gr2xU8DFrU+y2Y5QNXi5wvSsBp8WS 6C/70HQEy35uSyOjbjVlPi0/UKoelVw9dCO7HZBOb9lTd88hC4Gx90KFwpq6Ievf L20VNgOESC2y6kRbuLNbhQVsbT2Ijyz9NccVM5owFEbHkXDxJ0vQVzrNM999DVjb CC2v0NZMLPNJQn2RvC172QBOsOERxIRkZdJHcifydl7i2QNpr8+/YSnS7OSx3dA/ 3ZmTLejaiGUXdTGEI9dHy77s+adwTzGsH+INKotQG8qwUXzCLuUWN3GGK+Qof5Rk jbsGAoZ7GQz1/7NdEOcGW6pxD4mllk3McKMzNlMmddRDUPhSUg3WXu0c1AWGzfA1 ulk6fQDaTUjvs7nokuozhguKz8OKrT6S7x/iES5tPbXLhuDqfnUdYiQ+7m2beRb5 L9S9KK95HXnKJAI9WLOELj1vCrfbCGjlwz8YVSrwPtwwzP/wbB1Ni6tmwLrxHbLk SGyJEMnPs3mARIPDwDysyOs+3OUSx04uYW6YTSh8XyKNIxTCflRxr/iM5YyYEMvt lXMrp1sh4hc= =5oFu -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time.

The cpufreq-dt-platdev driver supports creation of cpufreq-dt platform device now, reuse that and remove similar code from platform code. Note that the complete routine imx27_dt_init() is removed as of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL); has same effect as a NULL .init_machine machine callback pointer.

ARM: imx: always use TWD on IMX6Q
There is no reason to limit the TWD to be used on SMP kernels only if the hardware has it available. On Wandboard i.MX6SOLO, running PREEMPT-RT and cyclictest I see as max immediately after start in idle: UP : ~90us SMP: ~50us UP + TWD: ~20us. Based on this numbers I prefer the TWD over the slightly slower MXC timer. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org> |

This is the bulk of GPIO changes for kernel v4.6:
Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected
to SPI to obtain a dirt-cheap output-only GPIO expander.
- Texas Instruments TPIC2810
- Texas Instruments TPS65218
- Texas Instruments TPS65912

ARM: imx: Do L2 errata only if the L2 cache isn't enabled
All the generic L2 cache handling code is encapsulated by a check if the L2 cache is enabled. If it's enabled already, the code is skipped. The write to the L2-Cache controller from non-secure world causes an imprecise external abort. This is needed in scenarios where one of the cores runs an other OS, e.g. an RTOS.

ARM: imx: select ARM_CPU_SUSPEND only for imx6
i.MX only needs to select ARM_CPU_SUSPEND manually for the
very specific case that CONFIG_PM_SLEEP is disabled and imx6
is used with CONFIG_PM enabled for runtime PM.
If we are building a kernel only for CPUs that are not using
the cpu_suspend() helper, we otherwise get a harmless
build warning:
warning: (ARCH_MXC && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM &&

requires it, in effect reverting commit

ARM: imx: Add msl code support for imx6qp
The i.MX6QP is a different SOC, but internally we treate it as i.MX6Q Rev_2.0 to maximum the code reusability. The chip silicon number we read from the ANADIG_DIGPROG is 0x630100. This patch add code to identify it as i.MX6QP Rev_1.0 when print out the silicon version. Signed-off-by: Bai Ping <ping.bai@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org> |

ARM: imx: enable big endian mode
Enable ARM big-endian mode on mach-imx. This requires adding some byte swapping in the debug functions (which otherwise hang forever) and of course the secondary core bringup. Tested (on top of 4.4) on i.MX6 HummingBoard quad-core (IMX6Q). The patch is pretty much as suggested by Arnd Bergmann, thanks!

ARM: imx: use endian-safe readl/readw/writel/writew
Instead of __raw_*, define imx_* to *_relaxed and use those. Using imx_* was requested by Arnd because *_relaxed tends to indicate that the code was carefully reviewed to not require any synchronisation and otherwise be safe, which isn't the case here with the automatic conversion.

GPIO bulk updates for the v4.5 kernel cycle:
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better reflect
the fact that this is not the GPIO struct device abstraction. We will
add that soon so this would be totallt confusing.
- It was noted that the driver .get_value() callbacks was
sometimes reporting negative -ERR values to the gpiolib core, expecting
them to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than zero"
to indicate that a line was active. As some would have bit 31 set to
indicate "line active" it clashed with negative error codes. This is
fixed by the largeish series clamping values in all drivers with
!!value to [0,1] and then augmenting the code to propagate error codes
to consumers. (Includes some ACKed patches in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of() design
pattern is indeed very nice, but we want to reform the struct gpio_chip
to be a non-volative, stateless business, and keep states internal to
the gpiolib to be able to hold on to the state when adding a proper
userspace ABI (character device) further down the road. To achieve this,
drivers need a handle at the internal state that is not dependent on
their struct gpio_chip() so we add gpiochip_add_data() and
gpiochip_get_data() following the pattern of many other subsystems.
All the "use gpiochip data pointer" patches transforms drivers to this
scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that removed.
Instead of having a separate mm_gpio_chip struct for these generic
drivers, merge that into struct gpio_chip, simplifying the code and
removing the need for separate and confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from the
OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
the branch is merged here too to account for infrastructural changes).
- The sx150x driver now supports the sx1502.

Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.
Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...
Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better
reflect the fact that this is not the GPIO struct device
abstraction. We will add that soon so this would be totallt

MTD updates for v4.5:
Generic MTD
* populate the MTD device 'of_node' field (and get a proper 'of_node' symlink
in sysfs)
- This yielded some new helper functions, and changes across a variety of
drivers
* partitioning cleanups, to prepare for better device-tree based partitioning
in the future
- Eliminate a lot of boilerplate for drivers that want to use OF-based
partition parsing
- The DT bindings for this didn't settle yet, so most non-cleanup portions
are deferred for a future release
NAND
* embed a struct mtd_info inside struct nand_chip
- This is really long overdue; too many drivers have to do the same silly
boilerplate to allocate and link up two "independent" structs, when in
fact, everyone is assuming there is an exact 1:1 relationship between a
NAND chips struct and its underlying MTD. This aids improved helpers and
should make certain abstractions easier in the future.
- Also causes a lot of churn, helped along by some automated code
transformations
* add more core support for detecting (and "correcting") bitflips in erased
pages; requires opt-in by drivers, but at least we kill a few bad
implementations and hopefully stave off future ones
* pxa3xx_nand: cleanups, a few fixes, and PM improvements
* new JZ4780 NAND driver
SPI NOR
* provide default erase function, for controllers that just want to send the
SECTOR_ERASE command directly
* fix some module auto-loading issues with device tree ("jedec,spi-nor")
* error handling fixes
* new Mediatek QSPI flash driver
Other
* cfi: force valid geometry Kconfig (finally!)
- this one used to trip up randconfigs occasionally, since bots aren't
deterred by big scary "advanced configuration" menus
More? Probably. See the commit logs.

gpio: generic: factor into gpio_chip struct
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make things simpler: include the fields directly into <linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix some of the member variables with bgpio_* and add proper kerneldoc while we're at it. Modify all users to handle the change and use a struct gpio_chip directly. And while we're at it: replace all container_of() dereferencing by gpiochip_get_data() and registering the gpio_chip with gpiochip_add_data().

ARM: use "depends on" for SoC configs instead of "if" after prompt
Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.
Please notice the difference between
config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7
and
config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7
These two are *not* equivalent!
In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.
The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)
For enabling/disabling sub-architectures, the latter is always correct.
As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).
[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent
and in making the lines shorter]

GPC irq domain is a child domain of GIC, now all of platform irqs are inside GPC domain, during the module populate, all devices irq should have correct type setting in GIC, however, there is no .irq_set_type callback setting in GPC, so the irq_set_type will be skipped and cause all irqs' type in /proc/interrupt are "edge" which mismatch with irq type setting in dtb file. Since GPC has no irq type setting, so just tell kernel to use irq_chip_set_type_parent.

- Removal of bockw platforms on shmobile, since the platform has now gone
completely multiplatform. Whee!
- move of the 32kHz timer on OMAP to a proper timesource
- Misc cleanup of older OMAP material (incl removal of one board file)
- Switch over to new common PWM lookup support for several platforms
There's also a handful of other cleanups across the tree, but the above are

Power management and ACPI updates for v4.4-rc1
- ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng).
The most significant change is to allow the AML debugger to be
built into the kernel. On top of that there is an update related
to the NFIT table (the ACPI persistent memory interface)
and a few fixes and cleanups.
- ACPI CPPC2 (Collaborative Processor Performance Control v2)
support along with a cpufreq frontend (Ashwin Chaugule).
This can only be enabled on ARM64 at this point.
- New ACPI infrastructure for the early probing of IRQ chips and
clock sources (Marc Zyngier).
- Support for a new hierarchical properties extension of the ACPI
_DSD (Device Specific Data) device configuration object allowing
the kernel to handle hierarchical properties (provided by the
platform firmware this way) automatically and make them available
to device drivers via the generic device properties interface
(Rafael Wysocki).
- Generic device properties API extension to obtain an index of
certain string value in an array of strings, along the lines of
of_property_match_string(), but working for all of the supported
firmware node types, and support for the "dma-names" device
property based on it (Mika Westerberg).
- ACPI core fix to parse the MADT (Multiple APIC Description Table)
entries in the order expected by platform firmware (and mandated
by the specification) to avoid confusion on systems with more than
255 logical CPUs (Lukasz Anaczkowski).

Merge tag 'pm+acpi-4.4-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management and ACPI updates from Rafael Wysocki:
"Quite a new features are included this time.
First off, the Collaborative Processor Performance Control interface
(version 2) defined by ACPI will now be supported on ARM64 along with
a cpufreq frontend for CPU performance scaling.
Second, ACPI gets a new infrastructure for the early probing of IRQ
chips and clock sources (along the lines of the existing similar
mechanism for DT).
Next, the ACPI core and the generic device properties API will now
support a recently introduced hierarchical properties extension of the
_DSD (Device Specific Data) ACPI device configuration object. If the
ACPI platform firmware uses that extension to organize device
properties in a hierarchical way, the kernel will automatically handle
it and make those properties available to device drivers via the
generic device properties API.
It also will be possible to build the ACPICA's AML interpreter
debugger into the kernel now and use that to diagnose AML-related
problems more efficiently. In the future, this should make it
possible to single-step AML execution and do similar things.
Interesting stuff, although somewhat experimental at this point.
Finally, the PM core gets a new mechanism that can be used by device
drivers to distinguish between suspend-to-RAM (based on platform
firmware support) and suspend-to-idle (or other variants of system
suspend the platform firmware is not involved in) and possibly
optimize their device suspend/resume handling accordingly.
In addition to that, some existing features are re-organized quite
substantially.
First, the ACPI-based handling of PCI host bridges on x86 and ia64 is
unified and the common code goes into the ACPI core (so as to reduce
code duplication and eliminate non-essential differences between the
two architectures in that area).
Second, the Operating Performance Points (OPP) framework is
reorganized to make the code easier to find and follow.
Next, the cpufreq core's sysfs interface is reorganized to get rid of
the "primary CPU" concept for configurations in which the same
performance scaling settings are shared between multiple CPUs.
Finally, some interfaces that aren't necessary any more are dropped
from the generic power domains framework.
On top of the above we have some minor extensions, cleanups and bug
fixes in multiple places, as usual.
Specifics:
- ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng).
The most significant change is to allow the AML debugger to be
built into the kernel. On top of that there is an update related
to the NFIT table (the ACPI persistent memory interface) and a few
fixes and cleanups.
- ACPI CPPC2 (Collaborative Processor Performance Control v2) support
along with a cpufreq frontend (Ashwin Chaugule).
This can only be enabled on ARM64 at this point.
- New ACPI infrastructure for the early probing of IRQ chips and
clock sources (Marc Zyngier).
- Support for a new hierarchical properties extension of the ACPI
_DSD (Device Specific Data) device configuration object allowing
the kernel to handle hierarchical properties (provided by the
platform firmware this way) automatically and make them available
to device drivers via the generic device properties interface
(Rafael Wysocki).
- Generic device properties API extension to obtain an index of
certain string value in an array of strings, along the lines of
of_property_match_string(), but working for all of the supported
firmware node types, and support for the "dma-names" device
property based on it (Mika Westerberg).
- ACPI core fix to parse the MADT (Multiple APIC Description Table)
entries in the order expected by platform firmware (and mandated by
the specification) to avoid confusion on systems with more than 255
logical CPUs (Lukasz Anaczkowski).
- Consolidation of the ACPI-based handling of PCI host bridges on x86
and ia64 (Jiang Liu).
- ACPI core fixes to ensure that the correct IRQ number is used to
represent the SCI (System Control Interrupt) in the cases when it
has been re-mapped (Chen Yu).
- New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede).
- ACPI EC driver fixes (Lv Zheng).
- Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri
Kosina, Rami Rosen, Rasmus Villemoes).

This patch adds suspend function for i.MX6UL, it supports "standby" and "mem" mode, for "standby" mode, SoC will enter STOP mode only, while for "mem" mode, SoC will enter STOP mode and DDR IO will be set to low power mode. As i.MX6UL contains a "Cortex-A7" ARM core which has no PL310, so we need to avoid any PL310 operations during suspend/resume, also, we need to flush Cortex-A7's inernal L2 cache before suspend.
