Linus Torvalds 9805529ec5 ARM: device tree updates for 5.11
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
    meant for faster Chromebooks and tablets. It gets added along with
    its reference design.
 
  - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
    generation, also added along with its reference board.  This one is
    still based on Cortex-A75/A55.
 
  - Mediatek MT8167 is a version of the already supported MT8516 chip,
    both based on Cortex-A35. It gets added along with the "Pumpkin"
    single board computer, but is likely to also make its way into low-end
    tablets in the future.
 
 For the already supported chips, there are a number of new boards.
 Interestingly there are more 32-bit machines added this time than
 64-bit. Here is a brief list of the new boards:
 
  - Three new Mikrotik router variants based on Marvell Prestera
    98DX3236, a close relative of the more common Armada XP
 
  - A reference board for the Marvell Armada 382
 
  - Three new servers using ASpeed baseboard management controllers,
    the actual machines being from Bytedance, Facebook and IBM,
    and one machine using the Nuvoton NPCM750 BMC.
 
  - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
 
  - The usual set of 32-bit i.MX industrial/embedded hardware:
    * Protonic WD3 (tractor e-cockpit)
    * Kamstrup OMNIA Flex Concentrator (smart grid platform)
    * Van der Laan LANMCU (food storage)
    * Altesco I6P (vehicle inspection stations)
    * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
 
  - DH electronics STM32MP157C DHCOM, a PicoITX carrier board
    for the aleady supported DHCOM module
 
  - Three new Allwinner SoC based single-board computers:
    * NanoPi R1 (H3 based)
    * FriendlyArm ZeroPi (H3 based)
    * Elimo Initium SBC (S3 based)
 
  - Ouya Game Console based on Nvidia Tegra 3
 
  - Version 5 of the already supported Zynq Z-Turn MYIR Board
 
  - LX2162AQDS, a reference platform for NXP Layerscape
    LX2162A, which is a repackaged 16-core LX2160A
 
  - A series of Kontron i.MX8M Mini baseboard/SoM versions
 
  - Espressobin Ultra, a new variant of the popular Armada 3700 based board,
 
  - IEI Puzzle-M801, a rackmount network appliance based on
    Marvell Armada 8040
 
  - Microsoft Lumia 950 XL, a phone
 
  - HDK855 and HDK865 Hardware development kits for Qualcomm
    sm8250 and sm8150, respectively
 
  - Three new board variants of the "Trogdor" Chromebook
    (sc7180)
 
  - New board variants of the Renesas based "Kingfisher" and
    "HiHope" reference boards
 
  - Kobol Helios64, an open source NAS appliance based on Rockchips
    RK3399
 
  - Engicam PX30.Core, a SoM based on Rockchip PX30, along with
    a few carrier boards.
 
 There is one conflict in mt6577_auxadc.txt, which got replaced in
 another tree and modified here, the modification is already part of
 the new file.

Linus Walleij feedaacdad Input: atmel_mxt_ts - fix up inverted RESET handler
This driver uses GPIO descriptors to drive the touchscreen RESET line. In
the existing device trees this has in conflict with intution been flagged
as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by
driving the line low (setting to 0) to enter reset state and driving the
line high (setting to 1) to get out of reset state.

The correct way to handle active low GPIO lines is to provide the
GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware)
and letting the GPIO framework invert the assertion (driving high) to a
low level and vice versa.

This is considered a bug since the device trees are incorrectly
mis-specifying the line as active high.

Fix the driver and all device trees specifying a reset line.

Uwe Kleine-König fa28d8212e ARM: dts: imx: default to #pwm-cells = <3> in the SoC dtsi files
The imx-pwm driver supports 3 cells and this is the more flexible setting.
So use it by default and overwrite it back to two for the files that
reference the PWMs with just 2 cells to minimize changes.

This allows to drop explicit setting to 3 cells for the boards that already
depend on this. The boards that are now using 2 cells explicitly can be
converted to 3 individually.

A quoted label reference doesn't expand to the node path and is taken as
a literal string. Dropping the quotes can fix this unless the baudrate
string is appended in which case we have to use the alias.

At least on VF610, the problem was masked by setting the console in
bootargs. Use the alias syntax with baudrate parameter so we can drop
setting the console in bootargs.

Lots of i.MX boards use the SGTL5000 codec, but not all get the warning
because only some reference the codec with "sound-dai" property. However,
the codec should always provide #sound-dai-cells regardless, so fix all
the occurrences.
