dc2535be1f We have a fairly balanced mix of clk driver updates and clk framework 
updates this time around. It's the usual pile of new drivers for new
 hardware out there and the normal small fixes and updates, but then we
 have some core framework changes too.
 
 In the core framework, we introduce support for a clk_get_optional() API
 to get clks that may not always be populated and a way to devm manage clkdev
 lookups registered by provider drivers. We also do some refactoring to simplify
 the interface between clkdev and the common clk framework so we can reuse the DT
 parsing and clk_get() path in provider drivers in the future. This work will
 continue in the next few cycles while we convert how providers specify clk
 parents.
 
 On the driver side, the biggest part of the dirstat is the Amlogic clk driver
 that got support for the G12A SoC. It dominates with almost half the overall
 diff, while the second largest part of the diff is in the i.MX clk driver
 that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor
 and Qualcomm drivers rounding out the big part of the dirstat because they both
 got new hardware support for SoCs. The rest is just various updates and non-critical
 fixes for existing drivers.
 
 Core:
  - Convert a few clk bindings to JSON schema format
  - Add a {devm_}clk_get_optional() API
  - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
  - Start rewriting clk parent registration and supporting device links
    by moving around code that supports clk_get() and DT parsing of the
    'clocks' property
 
 New Drivers:
  - Add Qualcomm MSM8998 RPM managed clks
  - IPA clk support on Qualcomm RPMh clk controllers
  - Actions Semi S500 SoC clk support
  - Support for fixed rate clks populated from an MMIO register
  - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
  - Add TMU (timer) clocks on Renesas RZ/G2E
  - Add Amlogic G12A Always-On Clock Controller
  - Add 32k clock generation for Amlogic AXG
  - Add support for the Mali GPU clocks on Amlogic Meson8
  - Add Amlogic G12A EE clock controller driver
  - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
  - Add i.MX8MM SoC clk driver support
 
 Removed Drivers:
  - Remove clps711x driver as the board support is gone
 
 Updates:
  - 3rd ECO fix for Mediatek MT2712 SoCs
  - Updates for Qualcomm MSM8998 GCC clks
  - Random static analysis fixes for clk drivers
  - Support for sleeping gpios in the clk-gpio type
  - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
  - Split LCDC into two clks on the Marvell MMP2 SoC
  - Various DT of_node refcount fixes
  - Get rid of CLK_IS_BASIC from TI code (yay!)
  - TI Autoidle clk support
  - Fix Amlogic Meson8 APB clock ID name
  - Claim input clocks through DT for Amlogic AXG and GXBB
  - Correct the DU (display unit) parent clock on Renesas RZ/G2E
  - Exynos5433 IMEM CMU crypto clk support (SlimSS)
  - Fix for the PLL-MIPI on the Allwinner A23
  - Fix Rockchip rk3328 PLL rate calculation
  - Add SET_RATE_PARENT flag on display clk of Rockhip rk3066
  - i.MX SCU clk driver clk_set_parent() and cpufreq support

3601fe43e8 This is the bulk of GPIO changes for the v5.1 cycle: 
Core changes:
 
 - The big change this time around is the irqchip handling in
   the qualcomm pin controllers, closely coupled with the
   gpiochip. This rework, in a classic fall-between-the-chairs
   fashion has been sidestepped for too long. The Qualcomm
   IRQchips using the SPMI and SSBI transport mechanisms have
   been rewritten to use hierarchical irqchip. This creates
   the base from which I intend to gradually pull support for
   hierarchical irqchips into the gpiolib irqchip helpers to
   cut down on duplicate code. We have too many hacks in the
   kernel because people have been working around the missing
   hierarchical irqchip for years, and once it was there,
   noone understood it for a while. We are now slowly adapting
   to using it. This is why this pull requests include changes
   to MFD, SPMI, IRQchip core and some ARM Device Trees
   pertaining to the Qualcomm chip family. Since Qualcomm have
   so many chips and such large deployments it is paramount
   that this platform gets this right, and now it (hopefully)
   does.
 
 - Core support for pull-up and pull-down configuration, also
   from the device tree. When a simple GPIO chip support a
   "off or on" pull-up or pull-down resistor, we provide a
   way to set this up using machine descriptors or device tree.
   If more elaborate control of pull up/down (such as
   resistance shunt setting) is required, drivers should be
   phased over to use pin control. We do not yet provide a
   userspace ABI for this pull up-down setting but I suspect
   the makers are going to ask for it soon enough. PCA953x
   is the first user of this new API.
 
 - The GPIO mockup driver has been revamped after some
   discussion improving the IRQ simulator in the process.
   The idea is to make it possible to use the mockup for
   both testing and virtual prototyping, e.g. when you do
   not yet have a GPIO expander to play with but really
   want to get something to develop code around before
   hardware is available. It's neat. The blackbox testing
   usecase is currently making its way into kernelci.
 
 - ACPI GPIO core preserves non direction flags when updating
   flags.
 
 - A new device core helper for devm_platform_ioremap_resource()
   is funneled through the GPIO tree with Greg's ACK.
 
 New drivers:
 
 - TQ-Systems QTMX86 GPIO controllers (using port-mapped
   I/O)
 
 - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
 
 - AMD G-Series PCH (Platform Controller Hub) GPIO driver.
 
 - Fintek F81804 & F81966 subvariants.
 
 - PCA953x now supports NXP PCAL6416.
 
 Driver improvements:
 
 - IRQ support on the Nintendo Wii (Hollywood) GPIO.
 
 - get_direction() support for the MVEBU driver.
 
 - Set the right output level on SAMA5D2.
 
 - Drop the unused irq trigger setting on the Spreadtrum
   driver.
 
 - Wakeup support for PCA953x.
 
 - A slew of cleanups in the various Intel drivers.

aebbfafc74 ARM: SoC platform updates for 5.1 
The APM X-Gene platform is now maintained by folks from Ampere
 computing that took over the product line a while ago, this gets
 reflected in the MAINTAINERS file.
 
 Cleanups continue on the older mach-davinci and mach-pxa platform,
 to get them to be more like the modern ones. For pxa, we
 now remove the Raumfeld platform code as it now works with
 device tree based booting.
 
 i.MX adds a couple new features for the i.MX7ULP SoC
 
 Mediatek gains support for a new SoC: MT7629 is a new wireless
 router platform, following MT7623.
 
 Aside from those, there are the usual minor cleanups and bugfixes
 across several platforms.

Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC platform updates from Arnd Bergmann:
 "The APM X-Gene platform is now maintained by folks from Ampere
  computing that took over the product line a while ago, this gets
  reflected in the MAINTAINERS file.

  Cleanups continue on the older mach-davinci and mach-pxa platform, to
  get them to be more like the modern ones. For pxa, we now remove the
  Raumfeld platform code as it now works with device tree based booting.

  i.MX adds a couple new features for the i.MX7ULP SoC

  Mediatek gains support for a new SoC: MT7629 is a new wireless router
  platform, following MT7623.

  Aside from those, there are the usual minor cleanups and bugfixes
  across several platforms"

0d2f2a3da1 platform/chrome: wilco_ec: Add RTC driver 
This Embedded Controller has an internal RTC that is exposed
as a standard RTC class driver with read/write functionality.

The driver is added to the drivers/rtc/ so that the maintainer of that
directory will be able to comment on this change, as that maintainer is
the expert on this system. In addition, the driver code is called
indirectly after a corresponding device is registered from core.c,
as opposed to core.c registering the driver callbacks directly.

To test:

d7dba6be0f dmaengine: dw: Remove misleading is_private property 
The commit a9ddb575d6

   ("dmaengine: dw_dmac: Enhance device tree support")

introduces is_private property in uncertain understanding what does it mean.

First of all, documentation defines DMA_PRIVATE capability as

Documentation/crypto/async-tx-api.txt:
  The DMA_PRIVATE capability flag is used to tag dma devices that should not be
  used by the general-purpose allocator. It can be set at initialization time
  if it is known that a channel will always be private. Alternatively,
  it is set when dma_request_channel() finds an unused "public" channel.

  A couple caveats to note when implementing a driver and consumer:
  1/ Once a channel has been privately allocated it will no longer be
     considered by the general-purpose allocator even after a call to
     dma_release_channel().
  2/ Since capabilities are specified at the device level a dma_device with
     multiple channels will either have all channels public, or all channels
     private.

Documentation/driver-api/dmaengine/provider.rst:
  - DMA_PRIVATE
    The devices only supports slave transfers, and as such isn't available
    for async transfers.

The capability had been introduced by the commit 59b5ec2144

  ("dmaengine: introduce dma_request_channel and private channels")

and some code didn't changed from that times ever.

Taking into consideration above and the fact that on all known platforms
Synopsys DesignWare DMA engine is attached to serve slave transfers,
the DMA_PRIVATE capability must be enabled for this device unconditionally.
Otherwise, as rightfully noticed in drivers/dma/at_xdmac.c:
  /*
   * Without DMA_PRIVATE the driver is not able to allocate more than
   * one channel, second allocation fails in private_candidate.
   */
because of of a caveats mentioned in above documentation excerpts.

So, remove conditional around DMA_PRIVATE followed by removal leftovers.

If someone wonders, DMA_PRIVATE can be not used if and only if the all channels
of the DMA controller are supposed to serve memory-to-memory like operations.
For example, EP93xx has two controllers, one of which can only perform
memory-to-memory transfers

Note, this change doesn't affect dmatest to be able to test such controllers.

 good, tiny cleanups is nice to see.  No new huge driver removal or
 addition, this release cycle, although there are lots of good IIO driver

22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
    therefore abort the operation before the commit phase (which is the
    NETDEV_CHANGEADDR event). From Petr Machata.

23) Add indirect call wrappers to avoid retpoline overhead, and use them
    in the GRO code paths. From Paolo Abeni.

24) Add support for netlink FDB get operations, from Roopa Prabhu.

25) Support bloom filter in mlxsw driver, from Nir Dotan.

26) Add SKB extension infrastructure. This consolidates the handling of
    the auxiliary SKB data used by IPSEC and bridge netfilter, and is
    designed to support the needs to MPTCP which could be integrated in
    the future.

27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.

f54005b508 mmc: pxa: Use GPIO descriptor for power 
After converting the PXA driver to use GPIO descriptors for
card detect and write protect it is relatively simple to
convert it to also use a descriptor for getting the optional
power control GPIO.

The polarity inversion flag can also go away from the platform
data since this is indicated in the GPIO machine descriptor
table.

80a68f387c mmc: pxamci: Delete platform data handling of CD and WP 
This deletes the code dealing with handling card detect
and write protect passed in as platform data and makes
the host rely on just GPIO descriptors.

The card read only inversion flag has to be kept around
for now, as the core cannot handle the inversion flags
on the descriptors yet.

Since we can now rely on the descriptors to have the
right polarity, we set the "override_active_level" to
false in mmc_gpiod_request_cd() and mmc_gpiod_request_ro().

d2951dfa07 mmc: s3cmci: Use the slot GPIO descriptor 
Simplify things by making the S3CMCI driver just use
slot GPIO with descriptors instead of passing around the
global GPIO numbers that we want to get rid of.

Getting the names of the GPIO chips into the machine
descriptor tables was a bit of a challenge but I think
I have them right.

The platform data supports passing in inversion flags, but
no platform is using them, and it is highly unlikely
that we will add more, so drop them. The long term plan
is to let the inversion flags on the GPIO machine
descriptor do the job.

The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is
what they are, and since we can now rely on the descriptors
to have the right polarity, we set the
"override_active_level" to false in mmc_gpiod_request_cd()
and mmc_gpiod_request_ro().

74ff81e16c mmc: sdhci: imx: Use the slot GPIO descriptor 
Simplify things by making the i.MX SDHCI driver just use
slot GPIO with descriptors instead of passing around the global
GPIO numbers that we want to get rid of.

As it turns out, just one single board is using the platform
data to pass in GPIOs numbers for CD and WP, so we augment this
to use a machine descriptor table instead.
