Commit 729dcffd1ed31 ("usb: dwc3: gadget: Add support for disabling
U1 and U2 entries") give detail explaination for user case of
disable u1 and u2 in gadget mode:
"Usecase 1:
When combining dwc3 with an redriver for a USB Type-C device
solution, itsometimes have problems with leaving U1/U2 for
certain hosts, resulting in link training errors and reconnects.
For this U1/U2 state entries may be avoided."
on imx8mq-evk board, we have typec and redriver used and android
reported unstable issue when use some host PC for adb, so to have
a better performance, we disable u1 and u2 entries.

After commit f7907e57aea2 ("regulator: fixed: add off-on-delay"), user
can use "off-on-delay-us" to define the regulator off-delay time.
For SD card, according to the spec requirement, for sd card power reset
operation, it need sd card supply voltage to be lower than 0.5v and keep
over 1ms, otherwise, next time power back the sd card supply voltage to
3.3v, sd card can't support SD3.0 mode again.
This patch add the off-on-delay-us to each board, make sure the sd power
reset behavior is align with the specification. Without this patch, when
do quick system suspend/resume test, some sd card can't work at SD3.0 mode
after system resume back.

The main Audio DAC used on the EVK board is wm8524
The EVK provides the MCLK to wm8524.
Digital interface is SAI2 which includes three signals:
SYNC_CLK, BCLK and DACDAT.
This patch sets:
* SAI2 pinctrl configuration
* clock hierarchy
* wm8524 codec
Then uses simple-card machine driver to connect them
into a sound card.

Pull ARM SoC device tree updates from Arnd Bergmann:
"This is a smaller update than the past few times, but with just over
500 non-merge changesets still dwarfes the rest of the SoC tree.
Three new SoC platforms get added, each one a follow-up to an existing
product, and added here in combination with a reference platform:
- Renesas RZ/A2M (R7S9210) 32-bit Cortex-A9 Real-time imaging
processor:
https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rza/rza2m.html
- Renesas RZ/G2E (r8a774c0) 64-bit Cortex-A53 SoC "for Rich Graphics
Applications":
https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rz/rzg/rzg2e.html
- NXP i.MX8QuadXPlus 64-bit Cortex-A35 SoC:
https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-8-processors/i.mx-8x-family-arm-cortex-a35-3d-graphics-4k-video-dsp-error-correcting-code-on-ddr:i.MX8X
These are actual commercial products we now support with an in-kernel
device tree source file:
- Bosch Guardian is a product made by Bosch Power Tools GmbH, based
on the Texas Instruments AM335x chip
- Winterland IceBoard is a Texas Instruments AM3874 based machine
used in telescopes at the south pole and elsewhere, see commit
d031773169df2 for some pointers:
- Inspur on5263m5 is an x86 server platform with an Aspeed ast2500
baseboard management controller. This is for running on the BMC.
- Zodiac Digital Tapping Unit, apparently a kind of ethernet switch
used in airplanes.
- Phicomm K3 is a WiFi router based on Broadcom bcm47094
- Methode Electronics uDPU FTTdp distribution point unit
- X96 Max, a generic TV box based on Amlogic G12a (S905X2)
- NVIDIA Shield TV (Darcy) based on Tegra210
And then there are several new SBC, evaluation, development or modular
systems that we add:
- Three new Rockchips rk3399 based boards:
- FriendlyElec NanoPC-T4 and NanoPi M4
- Radxa ROCK Pi 4
- Five new i.MX6 family SoM modules and boards for industrial
products:
- Logic PD i.MX6QD SoM and evaluation baseboad
- Y Soft IOTA Draco/Hydra/Ursa family boards based on i.MX6DL
- Phytec phyCORE i.MX6 UltraLite SoM and evaluation module
- MYIR Tech MYD-LPC4357 development based on the NXP lpc4357
microcontroller
- Chameleon96, an Intel/Altera Cyclone5 based FPGA development system
in 96boards form factor
- Arm Fixed Virtual Platforms(FVP) Base RevC, a purely virtual
platform for corresponding to the latest "fast model"
- Another Raspberry Pi variant: Model 3 A+, supported both in 32-bit
and 64-bit mode.
- Oxalis Evalkit V100 based on NXP Layerscape LS1012a, in 96Boards
enterprise form factor
- Elgin RV1108 R1 development board based on 32-bit Rockchips RV1108
For already supported boards and SoCs, we often add support for new
devices after merging the drivers. This time, the largest changes
include updates for
- STMicroelectronics stm32mp1, which was now formally launched last
week
- Qualcomm Snapdragon 845, a high-end phone and low-end laptop chip
- Action Semi S700
- TI AM654x, their recently merged 64-bit SoC from the OMAP family
- Various Amlogic Meson SoCs
- Mediatek MT2712
- NVIDIA Tegra186 and Tegra210
- The ancient NXP lpc32xx family
- Samsung s5pv210, used in some older mobile phones
Many other chips see smaller updates and bugfixes beyond that"
