[PATCH v3 0/3] Add Anbernic RG353P and RG503

[PATCH v3 0/3] Add Anbernic RG353P and RG503

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add the devicetrees for the Anbernic RG353P and RG503. This enables
all the hardware that is currently supported via mainline Linux.
The remaining hardware (for both devices) includes the display panel
and the battery. The RG353P also requires drivers to be written and
mainlined for the touchscreen.

Changes since V2:
 - Renamed buttons to be consistent with their externally labelled
   function. Internal labels (such as sw11) would not allow for reuse
   of as many buttons in the rgxx3.dtsi tree.
 - Removed pinctrl for LCD related functions. These will be re-added
   when the panel drivers are ready.
 - Changed name of cw2015@62 to power-monitor@62 to keep it generic.

Changes since V1:
 - Corrected node names to always have only dashes (no underscores),
   except for ones that require hard-coded names (the rk817 PMIC).
 - Corrected all node aliases to always have only underscores (no
   dashes).
 - Appended "regulator" to all the regulator node names, except ones
   that require hard-coded names (the rk817 PMIC).
 - Corrected name of RG353P. Previously was called RG353.
 - Changed name of sound node from rk817-sound to just sound.
 - Changed name of gpio-keys to gpio-keys-control and removed volume
   buttons.
 - Added new node of gpio-keys-vol and added volume buttons. This
   is so we can do autorepeat on these two buttons. Note that buttons
   under gpio-keys-control remain labelled in ascending order for the
   GPIO in use.
 - Added note to adc-keys node that we deviate from the BSP kernel to
   comply with Linux input guidelines regarding gamepad menu buttons.
 - Added note to sound node that audio is reversed for both speakers
   and headphones.
 - Added additional hardware details to commit message for devicetrees.

[PATCH v3 3/3] arm64: dts: rockchip: add Anbernic RG353P and RG503

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

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).
