Pull ARM DT updates from Arnd Bergmann:
"There are 40 branches this time, adding a lot of new hardware support,
and cleanups. Krzysztof Kozlowski continues his treewide cleanups.
There are a number of new SoCs, all of them as part of existing
families, and typically added along with a reference board:
- Renesas RZ/G2UL (R9A07G043) is the single-core version of the
RZ/G2L general-purpose MPU.
- Renesas RZ/V2M (R9A09G011) is a smart camera SoC
- Renesas R-Car V4H (R8A779G0) is an automotive chip with Cortex-A76
cores and deep learning accerlation.
- Broadcom BCM47622 is a new broadband SoC based on a quad Cortex-A7
and dual Wifi-6.
- Corstone1000 is a generic platform from Arm that is used for
designing custom SoCs, the support for now is for the Fixed Virtual
Platform emulation for it.
- Mediatek MT8195 (Kompanio 1200) is a high-end consumer chip used in
upcoming Chromebooks.
- NXP i.MXRT1050 is a Cortex-M7 based microcontroller, the first
MMU-less SoC to be added in a while
New machines based on already supported SoCs this time are mainly for
32-bit platforms and include:
- Two wireless routers based on Broadcom bcm4708
- 30 new boards based on NXP i.MX6, i.MX7 and i.MX8 families, mostly
for the industrial embedded market, and on NXP LS1021A based IOT
board.
- Two ethernet switches based on Microchip LAN966
- Eight Qualcomm Snapdragon based machines, including a smartwatch, a
Chromebook board and some phones
- Another phone based on the old ST-Ericsson Ux500 platform
- Seven STM32MP1 based boards
- Four single-board computers based on Rockchip RK3566/RK3568"

Due to many carrier boards pulling the usdhc1 signals up to 3.3 volt we
need to disable 1.8 volt signaling. Adding the no-1-8-v property
basically disables UHS-I modes by default.
Also pull-up the command and data lines to the +V3.3_1.8_SD rail and
set them to the 200 MHz speed grade (e.g. pinmux bits 7-6: meaning 11
SPEED_3_max_200MHz).
Explicitly specify a bus-width of <4> in the module-level device tree
include file and drop the no-1-8-v property from the carrier boards
device trees.

Move all Atmel nodes from the board-level into the main module-level
device tree and prepare the device trees for use with Atmel MXT device
tree overlays. Also, add required pinmux groups.
The common scheme for pin groups in touch screen overlays is as follows:
- pinctrl_atmel_conn - SODIMM 106/107 pins for INT/RST signals (default)
- pinctrl_atmel_adap - SODIMM 28/30 pins for INT/RST signals.

This adds the proper phy-supply to the FEC. This supply is actually
switched by a clock that is now properly stated. This has the advantage
to add a delay for that particular regulator which is needed.

The keeper causes an undesired jump behavior in ADC. To avoid the
problem, disable keeper before starting ADC.

The correct spelling for the property is gpios. Otherwise, the regulator
will neither reserve nor control any GPIOs. Thus, any SD/MMC card which
can use UHS-I modes will fail.

The current setting reflects about 86 Ohms of source-impedance
on the SDIO signals where the WiFi board is hooked up. PCB traces are
routed with 50 Ohms impedance and there are no serial resistors on
those traces.
This commit changes the source-impedance to 52 Ohms to better match our
hardware design.
The impedances given in this commit message refer to 3.3V operation.

The conversion of the spi-imx driver to use GPIO descriptors
in commit 8cdcd8aeee28 ("spi: imx/fsl-lpspi: Convert to GPIO descriptors")
helped to detect the following SPI chipselect polarity mismatch on an
imx6q-sabresd:
[ 4.854337] m25p80@0 enforce active low on chipselect handle
Prior to the above commit, the chipselect polarity passed via cs-gpios
property was ignored and considered active-low.
The reason for such mismatch is clearly explained in the comments inside
drivers/gpio/gpiolib-of.c:
* SPI children have active low chip selects
* by default. This can be specified negatively
* by just omitting "spi-cs-high" in the
* device node, or actively by tagging on
* GPIO_ACTIVE_LOW as flag in the device
* tree. If the line is simultaneously
* tagged as active low in the device tree
* and has the "spi-cs-high" set, we get a
* conflict and the "spi-cs-high" flag will
* take precedence.
To properly represent the SPI chipselect polarity, change it to active-low
when the "spi-cs-high" property is absent.

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.

Some pinmuxings are obviously wrong, originating from a copy/paste
error. This patch corrects that with the following strategy:
- Set all reserved bits to zero
- Leave drive strength and slew rate as is
- Add sensible pull and hysteresis depending on the function of the pin
- Not used pins are muxed to their reset-value defined by the SoC

Reduce the current drawn from VCC_BATT when the main power on the 3V3
pins to the module are switched off.
This switches off SoC internal pull resistors which are provided on the
module for TAMPER7 and TAMPER9 SoC pin and switches on a pull down
instead of a pullup for the USBC_DET module pin (TAMPER2).

Since commit d2d0ad2aec4a ("i2c: imx: use open drain for recovery
GPIO") GPIO lib expects this GPIO to be configured as open drain.
Make sure we define this GPIO as open drain in the device tree.
This gets rid of the following warning:
gpio-81 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file
Note that currently the i.MX pinctrl driver does not support
enabling open drain directly, so this patch has no effect in
practice. Open drain is enabled by the fixed pinmux entry.
