The Orange Pi Win has a microSD card slot which is connected via all

Also, as microSD does not have a write protect switch, we disable this
feature in the DT node.

On usual A64 board design the power of HDMI controller is connected to

output will be blank. Therefore the simplefb driver should keep this

device node, if the board is capable of outputing HDMI.

arm64: dts: allwinner: a64: orangepi-win: Add wifi and bluetooth nodes

The AP6212 is based on the Broadcom BCM43430 or BCM43438. The WiFi side
identifies as BCM43430, while the Bluetooth side identifies as BCM43438.

WiFi is connected to mmc1 and the Bluetooth side is connected to UART1
in a 4 wire configuration. Same as the WiFi side, due to being the same
chip and package, DLDO2 provides overall power via VBAT, and DLDO4
provides I/O power via VDDIO. The RTC clock output provides the LPO low
power clock at 32.768 kHz.

This patch enables WiFi and Bluetooth on OrangePi Win boards and adds
missing LPO clock on the WiFi side. PCM connection also exists for
Bluetooth audio, but it's not used here.

Bluetooth UART speed is set to 1.5 MBaud in order to be able transmit
audio. While module supports even higher speeds, currently sunxi clock
driver doesn't support higher speed.

Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

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"
