Update the i2c1 bus noting that the unknown/unused device at 0x3c is an
iSmartWare SW2001 "encryption IC".
Based on the documentation I was able to find, this IC appears to be
used to authenticate a device for certain programs to ensure they only
run on authorized devices as a form of digital rights management.

Add additional properties for the SDMMC2 node. Based on user feedback
these help correct some issues with probing the WiFi hardware.

Move device specific properties related to the ADC Joystick to
different board specific device trees. This is in preparation for
adding the Anbernic RG-Arc series of devices.

The 'regulator-init-microvolt' property is not currently supported by
any driver, it was simply carried on from downstream kernels.
The problem is also indicated by the following dtbs_check warning:
rk3588-rock-5b.dtb: pmic@0: regulators:dcdc-reg4: Unevaluated properties are not allowed ('regulator-init-microvolt' was unexpected)
Remove the invalid property from all affected DTS files.

The realtek Bluetooth module uses the same driver as the
realtek,rtl8822cs-bt and the realtek,rtl8723bs-bt, however by selecting
the 8723bs advanced power saving features are disabled that appear
to interfere with normal operation of the bluetooth module. This
change switches the compatible string to disable power saving. Without
this patch evtest of a paired bluetooth controller fails, with this
patch the controller operates as expected.

Each of the LEDs on the RGxx3 which is currently controlled via GPIO
can also be controlled via a PWM. Change each of the LEDs to PWM so
that users have the ability to adjust the brightness of the LEDs
according to their preference.

Anbernic RG353V and RG353VS are both RK3566 based handheld gaming devices
from Anbernic.
They are functionally very similar to the RG353P with the following
distinct differences:
- The battery size of the RG353V and RG353VS is 3200mAh instead of
3500mAh.
- The audio uses the PMIC's internal amplifier for a mono speaker
instead of an external amplifier with stereo speakers.
- The GPIOs for the R1 and R2 buttons are switched.
As for the differences between the RG353V and RG353VS, they are as
follows:
- The RG353VS has no touchscreen on i2c2.
- The RG353VS has no eMMC.
- The RG353VS has 1GB of RAM instead of 2GB.

Anbernic RG353P and RG503 are both RK3566 based handheld gaming devices
from Anbernic.
Both devices have:
- 2 SDMMC slots.
- A Realtek rtl8821cs WiFi/Bluetooth adapter.
- A mini HDMI port.
- A USB C host port and a USB C otg port (currently only working as
device).
- Multiple GPIO buttons and a single ADC button.
- Dual analog joysticks controlled via a GPIO mux.
- A headphone jack with amplified stereo speakers via a SGM4865 amp.
- A PWM based vibrator for force feedback.
The RG353P has:
- 2GB LPDDR4 RAM.
- A 32GB eMMC.
- A 3.5 inch 640x480 4-lane DSI panel of unknown origin with an i2c
controlled touchscreen (touchscreen is a Hynitron CST340).
The RG503 has:
- 1GB LPDDR4 RAM.
- A 5 inch 960x544 AMOLED 2-lane DSI/DBI panel manufactured by Samsung
with part number ams495qa04. Data for this panel is provided via the
DSI interface, however commands are sent via a 9-bit 3-wire SPI
interface. The MISO pin of SPI3 of the SOC is wired to the input of
the panel, so it must be bitbanged.
This devicetree enables the following hardware:
- HDMI (plus audio).
- Analog audio, including speakers.
- All buttons.
- All SDMMC/eMMC/SDIO controllers.
- The ADC joysticks (note a pending patch is required to use them).
- WiFi/Bluetooth (note out of tree drivers are required).
- The PWM based vibrator motor.
The following hardware is not enabled:
- The display panels (drivers are being written and there are issues
with the upstream DSI and VOP2 subsystems).
- Battery (driver pending).
- Touchscreen on the RG353P (note the i2c2 bus is enabled for it).
