11777ee8b0 Merge branch 'i2c/for-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
 "i2c core:

   - huge improvements and refactorizations of the Linux I2C
     documentation (lots of thanks to Luca for doing it and Jean for the
     careful review)

   - subsystem wide API conversion to i2c_new_client_device()

   - remove obsolete parport-light driver

   - smaller core updates (removal of 'extern', enabling more compile
     testing, use more helper macros)

   - and quite a bunch of driver updates (new IDs, simplifications,
     better PM, support of atomic transfers and other improvements)

  i2c-mux:

   - The main feature is the idle-state rework of the pca954x driver
     from Biwen Li

  at24 driver:

   - minor maintenance: update the license tag, sort headers

   - move support for the write-protect pin into nvmem core

   - add a reference to the new wp-gpios property in nvmem to at25
     bindings

   - add support for regulator and pm_runtime control"

14f4957313 dt-bindings: nvmem: new optional property wp-gpios
Several memories have a write-protect pin, that when pulled high, it
blocks the write operation.

On some boards, this pin is connected to a GPIO and pulled high by
default, which forces the user to manually change its state before
writing.

Instead of modifying all the memory drivers to check this pin, make
the NVMEM subsystem check if the write-protect GPIO being passed
through the nvmem_config or defined in the device tree and pull it
low whenever writing to the memory.

Add a new optional property to the device tree binding document, which
allows to specify the GPIO line to which the write-protect pin is
connected.

Some binding that were introduced early on got a comment to enable
additionalProperties, but we couldn't due to the generic properties being
reported as errors.

The way we're dealing with this now is to use the draft-08's
unevaluatedProperties (even though the tools doesn't do anything with it
yet).

Let's convert those old bindings to it.

 "Here is the big char/misc driver patch pull request for 5.1-rc1.

  The largest thing by far is the new habanalabs driver for their AI
  accelerator chip. For now it is in the drivers/misc directory but will
  probably move to a new directory soon along with other drivers of this
  type.

  Other than that, just the usual set of individual driver updates and
  fixes. There's an "odd" merge in here from the DRM tree that they
  asked me to do as the MEI driver is starting to interact with the i915
  driver, and it needed some coordination. All of those patches have
  been properly acked by the relevant subsystem maintainers.

  All of these have been in linux-next with no reported issues, most for

ea2698597e nvmem: sunxi-sid: add support for H5's SID controller
The H5 SoC have a SID controller that looks like the one in A64, the
cells are in the same offset but doesn't contain the same data (thermal
sensor calibration for example).
Add a binding for it.

721afaa2ae Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree updates from Olof Johansson:
 "As always, a large number of DT updates. Too many to enumerate them
  all, but at a glance:

  New SoCs introduced in this release:

   - Amlogic:
      + Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some
        set top boxes and other products.

   - Mediatek:
      + MT7623A, which is a flavor of the MT7623 family with other
        on-chip ethernet options.

   - Qualcomm:
      + SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845
        (Cortex-A75/A55 derivative) SoC that's one of the current
        high-end mobile SoCs.

        It's great to see mainline support for it. So far, you can't do
        much with it, since a lot of peripherals are not yet in the DTs
        but driver support for USB, GPU and other pieces are starting to
        trickle in. This might end up being a well-supported SoC
        upstream if the momentum keeps up.

   - Renesas:
      + R8A77990, a.k.a R-Car E3, a new automotive
        entertainment-targeted SoC. Currently only one Cortex-A53 CPU is
        enabled, we are eagerly awaiting more. So far, basic drivers
        such as serial, gpios, PMU and ethernet are enabled.
      + R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR
        GPU. Same here, basic set of drivers such as serial, gpios and
        ethernet enabled, and SMP support is also forthcoming.

   - STMicroelectronics:
      + STM32F469, very similar tih STM32F429 but with display support

  Enhancements to SoCs/platforms (DTS contents, some driver portions
  might not be in yet):
   - Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc
   - Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets
   - Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces
   - Marvell Berlin2CD: SMP support, thermal sensors
   - Mediatek MT7623: Highspeed DMA, audio support
   - Qualcomm IPQ8074 PCIe support, MSM8996 UFS support
   - Renesas: Watchdog and PMU support across many platforms
   - Rockchip RK3399: USB3 OTG support
   - Samsung Exynos: Audio-over-HDMI on Odroid X/X2/U3
   - STMicro STM32: Lots of peripherals added to STM32MP175C
   - Uniphier: Ethernet support

  New boards:
   - Allwinner A20: Olimex A20-SOM-EVB-eMMC variant
   - Allwinner H2+: Libre Computer ALL-H3-CC (h2+ version)
   - Allwinner A33: Nintendo NES/SuperNES Classic Edition
   - Aspeed: S2600WF, Inventec Lanyang BMC, Portwell Neptune
   - Berlin2CD: Valve Steam Link
   - Broadcom BCM5301X: Luxul XAP-1610 and XWR-3150 V1
   - Broadcom: Raspberry Pi 3 B+
   - Mediatek MT7623N and MT7623A: reference boards
   - Meson 8M2: Tronsmart MXIII Plus
   - NXP i.MX: Engicam i.CoreM6, DHCOM iMX6 SOM, BTicino i.MX6DL Mamoj
   - Qualcomm MSM8974: Sony Xperia Z1 Compact support
   - Qualcomm SDM845: MTP development board
   - Renesas: Ebisu R8A77990 board
   - Renesas RZ/G1C: iwg23s: iWave G235-SDB
   - TI am335x: Pocketbeagle support"
