Exynos SoCs have Chipid, for identification of product IDs and SoC
revisions. This patch intends to provide initialization code for all
these functionalities, at the same time it provides some sysfs entries
for accessing these information to user-space.
This driver uses existing binding for exynos-chipid.
Changes by Bartlomiej:
- fixed return values on errors
- removed bogus kfree_const()
- added missing Exynos4210 EVT0 id
- converted code to use EXYNOS_MASK define
- fixed np use after of_node_put()
- fixed too early use of dev_info()
- made driver fail for unknown SoC-s
- added SPDX tag
- updated Copyrights

We have another fix to disable voltage switching for am57xx SDIO as
the bootrom cannot handle all the voltages after a reset that thought
I had already sent a pull request for earlier but forgot. And we also
update dra74x iodelay configuration for mmc3 to use the recommended
values.
Then I noticed we had introduced few new boot warnings with the various
recent ti-sysc changes and wanted to fix those. I also noticed we still
have too many warnings to be able to spot the real ones easily and fixed
up few of those. Sure some of the warnings have been around for a long
time and few of the fixes could have waited for the merge window, but
having more usable dmesg log level output is a valuable.
Other fixes are IO size correction for am335x UARTs that cause issues
for at least FreeBSD using the same device tree file that checks that
the child IO range is not larger than the parent has.
For omap1 ams-delta keyboard we need to fix a irq ack that broke with
all the recent gpio changes.
And there are also few static checker warning fixes for recent am335x
PM changes and ti-sysc driver and one switch fall-though update.

We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM Mali
GPU devices added to device trees, since the DRM drivers have now been
merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Polish and fixes for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now at
feature parity with TX1

SoC platform changes. Main theme this merge window:
- The Netx platform (Netx 100/500) platform is removed by Linus Walleij--
the SoC doesn't have active maintainers with hardware, and in
discussions with the vendor the agreement was that it's OK to remove.
- Russell King has a series of patches that cleans up and refactors
SA1101 and RiscPC support.

Convert docs to ReST and add them to the arch-specific
book.
The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.
The changes were mostly to mark literal blocks and add a few
missing section title identifiers.
One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Here is the big USB and PHY driver pull request for 5.3-rc1.
Lots of stuff here, all of which has been in linux-next for a while with
no reported issues. Nothing is earth-shattering, just constant forward
progress for more devices supported and cleanups and small fixes:
- USB gadget driver updates and fixes
- new USB gadget driver for some hardware, followed by a quick revert
of those patches as they were not ready to be merged...
- PHY driver updates
- Lots of new driver additions and cleanups with a few fixes mixed in.

This is a bug in clang that will be fixed in the future, but in order
to build cleanly with clang-8, it would be helpful to shut up this
warning. This file is the only instance reported by kernelci at the

The best solution I could come up with is to move the BIT() usage
out of the macro into the instantiation, so we can avoid using
BIT(-1).

In some software releases the firmware images are not split up with each
loadable segment in it's own file. Check the size of the loaded firmware
to see if it still contains each segment to be loaded, before falling
back to the split-out segments.

The irqchip driver depends on the SoC specific driver, but we want
to be able to compile-test it elsewhere:
WARNING: unmet direct dependencies detected for TI_SCI_INTA_MSI_DOMAIN
Depends on [n]: SOC_TI [=n]
Selected by [y]:

Rearrange the Kconfig and Makefile so we build the soc driver whenever
its users are there, regardless of the SOC_TI option.

The biggest part here is a set of patches removing unnecesary variables
from several drivers.
Meson-g12a's dwc3 glue implemented IRQ-based OTG/DRD role swap.
Qcom's dwc3 glue added support for ACPI, mainly for the AArch64-based
SoCs.
DWC3 also got support for Intel Elkhart Lake platforms.

Another round of SPDX updates for 5.2-rc6
Here is what I am guessing is going to be the last "big" SPDX update for
5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that
were "easy" to determine by pattern matching. The ones after this are
going to be a bit more difficult and the people on the spdx list will be
discussing them on a case-by-case basis now.
Another 5000+ files are fixed up, so our overall totals are:
Files checked: 64545
Files with SPDX: 45529
Compared to the 5.1 kernel which was:
Files checked: 63848
Files with SPDX: 22576
This is a huge improvement.
Also, we deleted another 20000 lines of boilerplate license crud, always
nice to see in a diffstat.

Pull still more SPDX updates from Greg KH:
"Another round of SPDX updates for 5.2-rc6
Here is what I am guessing is going to be the last "big" SPDX update
for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates
that were "easy" to determine by pattern matching. The ones after this
are going to be a bit more difficult and the people on the spdx list
will be discussing them on a case-by-case basis now.
Another 5000+ files are fixed up, so our overall totals are:
Files checked: 64545
Files with SPDX: 45529
Compared to the 5.1 kernel which was:
Files checked: 63848
Files with SPDX: 22576
This is a huge improvement.
Also, we deleted another 20000 lines of boilerplate license crud,
always nice to see in a diffstat"

tegra_powergate_sequence_power_up() powers up partition and also enables
clock & reset. However, if a controller like PCIe have multiple clocks
& resets and they need to be enabled in a sequence, driver must use
standalone function tegra_powergate_power_on() to power up partition.
Export tegra_powergate_power_on() to allow Tegra controller drivers to
unpower gate partition independent to clock & reset.

The reg property represents the address and size on the bus that a
device lives, but for APR the parent is a rpmsg bus, which does not have
numerical addresses. Simply defining #address/#size-cells to 1 and 0,
respectively, to silence the compiler is not an appropriate solution.

The Always On Subsystem (AOSS) Qualcomm Messaging Protocol (QMP) driver
is used to communicate with the AOSS for certain side-channel requests,
that are not available through the RPMh interface.
The communication is a very simple synchronous mechanism of messages
being written in message RAM and a doorbell in the AOSS is rung. As the
AOSS has processed the message length is cleared and an interrupt is
fired by the AOSS as acknowledgment.
The driver exposes the QDSS clock as a clock and the low-power state
associated with the remoteprocs in the system as a set of power-domains.

The comment "No QE ever has fewer than 28 SNUMs" is false; e.g. the
MPC8309 has 14. The code path returning -EINVAL is also a recipe for
instant disaster, since the caller (qe_snums_init) uncritically
assigns the return value to the unsigned qe_num_of_snum, and would
thus proceed to attempt to copy 4GB from snum_init_46[] to the snum[]
array.
So fold the handling of the legacy fsl,qe-num-snums into
qe_snums_init, and make sure we do not end up using the snum_init_46
array in cases other than the two where we know it makes sense.

Conveniently, of_property_read_variable_u8_array does exactly what we
need: If the property fsl,qe-snums is found (and has an allowed size),
the array of values get copied to snums, and the return value is the
number of snums - we cannot assign directly to num_of_snums, since we

The current array of struct qe_snum use 256*4 bytes for just keeping
track of the free/used state of each index, and the struct layout
means there's another 768 bytes of padding. If we just unzip that
structure, the array of snum values just use 256 bytes, while the
free/inuse state can be tracked in a 32 byte bitmap.
So this reduces the .data footprint by 1760 bytes. It also serves as
preparation for introducing another DT binding for specifying the snum
values.

Recent changes have made it much more probable that clocks are not
available yet when the FUSE driver is first probed. However, that is a
situation that the driver can cope with just fine.
To avoid confusion, don't output an error when this happens.

For interrupts that are not wakeup sources but that may end up getting
mapped through the PMC as interrupt parent (this can happen for GPIOs),
return early in order to avoid a subsequent crash from an out-of-bounds
access to the register region.

Add a couple of new APIs to check the probing status of the required
cpu bound qman and bman portals:
'int bman_portals_probed()' and 'int qman_portals_probed()'.
They return the following values.
* 1 if qman/bman portals were all probed correctly
* 0 if qman/bman portals were not yet probed
* -1 if probing of qman/bman portals failed
Portals are considered successful probed if no error occurred during
the probing of any of the portals and if enough portals were probed
to have one available for each cpu.
The error handling paths were slightly rearranged in order to fit this
new functionality without being too intrusive.
Drivers that use qman/bman portal driver services are required to use
these APIs before calling any functions exported by these drivers or
otherwise they will crash the kernel.
First user will be the dpaa1 ethernet driver, coming in a subsequent

With the system coprocessor managing the range allocation of the
inputs to Interrupt Aggregator, it is difficult to represent
the device IRQs from DT.
The suggestion is to use MSI in such cases where devices wants
to allocate and group interrupts dynamically.
Create a MSI domain bus layer that allocates and frees MSIs for
a device.
APIs that are implemented:
- ti_sci_inta_msi_create_irq_domain() that creates a MSI domain
- ti_sci_inta_msi_domain_alloc_irqs() that creates MSIs for the
specified device and resource.
- ti_sci_inta_msi_domain_free_irqs() frees the irqs attached to the device.
- ti_sci_inta_msi_get_virq() for getting the virq attached to a specific event.

When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but
not REGMAP_MMIO, so the kernel fails to link with an undefined reference
to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in
drivers/base/regmap/Kconfig.
This creates the following dependency loop:
drivers/of/Kconfig:68: symbol OF_IRQ depends on IRQ_DOMAIN
kernel/irq/Kconfig:63: symbol IRQ_DOMAIN is selected by REGMAP
drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_MMIO
drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by SUNXI_SRAM
drivers/soc/sunxi/Kconfig:4: symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI
drivers/usb/musb/Kconfig:63: symbol USB_MUSB_SUNXI depends on GENERIC_PHY
drivers/phy/Kconfig:7: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
drivers/phy/broadcom/Kconfig:29: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
drivers/net/phy/Kconfig:12: symbol MDIO_BUS default is visible depending on PHYLIB
drivers/net/phy/Kconfig:181: symbol PHYLIB is selected by ARC_EMAC_CORE
drivers/net/ethernet/arc/Kconfig:18: symbol ARC_EMAC_CORE is selected by ARC_EMAC
drivers/net/ethernet/arc/Kconfig:24: symbol ARC_EMAC depends on OF_IRQ
To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY
instead of depending on it. This matches the use of GENERIC_PHY by all
but two other drivers.

This series adds support for am437x RTC-only mode in suspend. In the
RTC-only mode suspend, everything is shut down except the RTC. This
makes the power consumption very low for suspend mode.
To support RTC-only mode, we need to export omap_rtc_power_off_program()
from the rtc driver and improve PM code to save and restore the wkup
domain context. As RTC-only mode depends on the device being wired
properly for things like memory, we need to also check for the machine
type before we allow it. We also need to run DDR3 hardware leveling on
resume.
Note that there is a trivial merge conflict between the RTC branch
and these changes where the RTC branch makes tm2bcd() a void function
and the error handling parts can be just dropped.

PM changes for am335x and am437x
This series adds support for am437x RTC-only mode in suspend. In the
RTC-only mode suspend, everything is shut down except the RTC. This
makes the power consumption very low for suspend mode.
To support RTC-only mode, we need to export omap_rtc_power_off_program()
from the rtc driver and improve PM code to save and restore the wkup
domain context. As RTC-only mode depends on the device being wired
properly for things like memory, we need to also check for the machine
type before we allow it. We also need to run DDR3 hardware leveling on
resume.
Note that there is a trivial merge conflict between the RTC branch
and these changes where the RTC branch makes tm2bcd() a void function
and the error handling parts can be just dropped.

Commit 8df127456f ("soc/tegra: pmc: Enable XUSB partitions on boot")
was added as a workaround to ensure that the XUSB powergates or domains
were turned on early during boot because as this time the Tegra XHCI
driver did not handle the power domains at all. Now that the Tegra XHCI
driver has been updated to properly managed the power domains, the
workaround to enable the XUSB power domain early has been removed. This
also means that we can now move the initialisation of the powergates
into the PMC driver probe. Therefore, move the powergate initialisation
into the PMC driver probe and return any errors detected. To handle any
errors, functions to cleanup and remove any power-domains registered
with the generic power-domain framework have been added.
Finally the initialisation of the 'powergates_available' bitmask is kept
in the PMC early init function to allow the legacy PMC powergate APIs to
be called during early boot for enabling secondary CPUs on 32-bit Tegra
devices.

Commit 5f84bb1a40 ("soc/tegra: pmc: Add sysfs entries for reset info")
added sysfs entries for Tegra reset source and level. However, these
sysfs are not removed on error and so if the registering of PMC device
is probe deferred, then the next time we attempt to probe the PMC device
warnings such as the following will be displayed on boot ...
sysfs: cannot create duplicate filename '/devices/platform/7000e400.pmc/reset_reason'
Fix this by calling device_remove_file() for each sysfs entry added on
failure. Note that we call device_remove_file() unconditionally without
checking if the sysfs entry was created in the first place, but this
should be OK because kernfs_remove_by_name_ns() will fail silently.

Commit 5f84bb1a40 ("soc/tegra: pmc: Add sysfs entries for reset info")
added support for reading the Tegra reset source and level from sysfs.
However, there are a few issues with this commit which are ...
1. The number of reset sources for Tegra210 is defined as 5 but it
should be 6.
2. The number of reset sources for Tegra186 is defined as 13 but it
should be 15.
3. The SoC data variables num_reset_sources and num_reset_levels are
defined but never used.
Fix the above by ...
1. Removing the reset source 'AOTAG' from the tegra30_reset_sources
because this is only applicable for Tegra210.
2. Adding a new tegra210_reset_sources structure for Tegra210 reset
sources.
3. Correct the number of reset sources for Tegra210 and Tegra186 by
using the ARRAY_SIZE macro.
4. Updating the functions reset_reason_show() and reset_level_show()
to check whether the value read is valid. While we are at it
clean-up these functions to remove an unnecessary u32 variable.

The rk3288 SoC has two PWM implementations available, the "old"
implementation and the "new" one. You can switch between the two of
them by flipping a bit in the grf.
The "old" implementation is the default at chip power up but isn't the
one that's officially supposed to be used. ...and, in fact, the
driver that gets selected in Linux using the rk3288 device tree only
supports the "new" implementation.
Long ago I tried to get a switch to the right IP block landed in the
PWM driver (search for "rk3288: Switch to use the proper PWM IP") but
that got rejected. In the mean time the grf has grown a full-fledged
driver that already sets other random bits like this. That means we
can now get the fix landed.
For those wondering how things could have possibly worked for the last
4.5 years, folks have mostly been relying on the bootloader to set
this bit. ...but occasionally folks have pointed back to my old patch
series [1] in downstream kernels.

During RTC-only suspend, power is lost to the wkup domain, so we need to
save and restore the state of that domain. We also need to store some
information within the RTC registers so that u-boot can do the right thing
at powerup.
The state is entered by getting the RTC to bring the pmic_power_en line low
which will instruct the PMIC to disable the appropriate power rails after
putting DDR into self-refresh mode. To bring pmic_power_en low, we need to
get an ALARM2 event. Since we are running from SRAM at that point, it means
calculating what the next second is (via ASM) and programming that into the
RTC. This patch also adds support for wake up source detection.

we introduced packages ids using the full 8bit value, but in the function
socinfo_to_package_id() the id was filtered with the 0xf0 mask.
While the 0xf0 mask is valid for most board, it filters out the lower
4 bits which encodes some characteristics of the chip.
This patch moves the mask into the meson_gx_package_id table to be applied
on each package name independently and add the correct mask for some
specific entries.
An example is the S905, in the vendor code the S905 is package_id
different from 0x20, and S905M is exactly 0x20.
Another example are the The Wetek Hub & Play2 boards using a S905-H
variant, which is the S905 SoC with some licence bits enabled.
These licence bits are encoded in the lower 4bits, so to detect
the -H variant, we must detect the id == 0x3 with the 0xf mask.

Pull ARM SoC driver updates from Arnd Bergmann:
"As usual, the drivers/tee and drivers/reset subsystems get merged
here, with the expected set of smaller updates and some new hardware
support. The tee subsystem now supports device drivers to be attached
to a tee, the first example here is a random number driver with its
implementation in the secure world.
Three new power domain drivers get added for specific chip families:
- Broadcom BCM283x chips (used in Raspberry Pi)
- Qualcomm Snapdragon phone chips
- Xilinx ZynqMP FPGA SoCs
One new driver is added to talk to the BPMP firmware on NVIDIA
Tegra210
Existing drivers are extended for new SoC variants from NXP, NVIDIA,
Amlogic and Qualcomm"

The separate GPHY Firmware loader driver is not used any more, the GPHY
firmware is now loaded by the GSWIP switch driver which also makes use
of the GPHY.
Remove the old unused GPHY firmware loader driver.
The GPHY firmware is useless without an Ethernet and switch driver, it
should not harm if loading this does not work for system using an old
device tree.
I am not aware of any vendor separating the device tree from the kernel
binary, it should be ok to remove this.

- Stefan updates the BCM2835 SoC driver with downstream properties and
uses that to implement a reboot notifier to tell the VC4 firmware when
Linux on the ARM CPU is rebooting
- Eric adds a proper power domain driver for the BCM283x SoCs and
updates a bunch of drivers to have a better and clearer Device Tree
definition to support power domains/breaking up of functionality. This
requires converting the existing watchdog driver into a MFD and then
breaking up the functionality into separate drivers and finally
updating the DTS files to leverage the power domains information.
- Wei provides a fix for making a symbol static

Merge tag 'arm-soc/for-5.1/drivers' of https://github.com/Broadcom/stblinux into arm/drivers
This pull request contains Broadcom ARM/ARM64/MIPS based SoCs changes
for 5.1, please pull the following:
- Stefan updates the BCM2835 SoC driver with downstream properties and
uses that to implement a reboot notifier to tell the VC4 firmware when
Linux on the ARM CPU is rebooting
- Eric adds a proper power domain driver for the BCM283x SoCs and
updates a bunch of drivers to have a better and clearer Device Tree
definition to support power domains/breaking up of functionality. This
requires converting the existing watchdog driver into a MFD and then
breaking up the functionality into separate drivers and finally
updating the DTS files to leverage the power domains information.
- Wei provides a fix for making a symbol static
* tag 'arm-soc/for-5.1/drivers' of https://github.com/Broadcom/stblinux:
ARM: bcm283x: Switch V3D over to using the PM driver instead of firmware.

Currently the data structure for llc-slice is devm allocated and
stored as a global but never cleared if the probe function fails.
This is a problem because devm managed memory gets freed on probe
failure the API functions could access the pointer after it has been
freed.
Initialize the drv_data pointer to an error and reset it to an error
on probe failure or device destroy and add protection to the API
functions to make sure the memory doesn't get accessed.
