Pull ARM device tree updates from Arnd Bergmann:
"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"

Use the correct pin for the i2c scl signal else we can't access the
SoM eeprom.

Set it to max. allowed 375kHz for faster transfers. The limit is given
by the erratum [1].

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 patch adds the following interfaces according the SMARC Spec 1.1
[1] and provided schematics:
- SMARC SPI0/1
Note: Since Kontron still uses silicon revisions below 1.3 they have
add a spi-nor to implement Workaround #1 of erratum ERR006282.
- SMARC SDIO
- SMARC LCD
- SMARC HDMI
- SMARC Management pins
Note: Kontron don't route all of these pins to the i.MX6, some are
routed to the SoM CPLD.
- SMARC GPIO
- SMARC CSI Camera
Note: As specified in [1] the data lanes are shared to cover the
csi and the parallel case. The case depends on the baseboard so
muxing the data lanes is not part of this patch.
- SMARC I2S
- SMARC Watchdog
Note: The watchdog output pin is routed to the CPLD and the SMARC
header. The CPLD performs a reset after a 30s timeout so we
need to enable the watchdog per default.
- SMARC module eeprom
Due to the lack of hardware not all of these interfaces are tesetd.
