This series adds initial support for the Radxa ZERO 3W/3E boards.
The Radxa ZERO 3W/3E is an ultra-small, high-performance single board
computer based on the Rockchip RK3566, with a compact form factor and
rich interfaces.
Schematic for ZERO 3W and ZERO 3E can be found at:
https://dl.radxa.com/zero3/docs/hw/3w/radxa_zero_3w_v1110_schematic.pdf
https://dl.radxa.com/zero3/docs/hw/3e/radxa_zero_3e_v1200_schematic.pdf
Changes in v2:
- Collect acked-by tag
- Add to Makefile
- Add patch to fix #sound-dai-cells warning
Changes in v3:
- Fix devicetree spelling
- Sort hdmi-con, leds, pmic@20 and regulator@40 nodes
- Change to regulator-off-in-suspend for vdd_logic
- Drop patch to fix #sound-dai-cells warning, similar patch [1] already
exists
Changes in v4:
- Change compatible of vdd_logic
- Add vcc5v_midu and vbus regulator and related vcc8/vcc9-supply prop
- Adjust clock_in_out prop for gmac1
- Add cap-mmc-highspeed prop to sdhci
- Add sdmmc1 and uart1 nodes used for wifi/bt on 3W
- Rename rk3566-radxa-zero3.dtsi to rk3566-radxa-zero-3.dtsi
- Rebase on latest mmind/for-next tree

2.43.2
The Radxa ZERO 3W/3E is an ultra-small, high-performance single board
computer based on the Rockchip RK3566, with a compact form factor and
rich interfaces.
The ZERO 3W and ZERO 3E are basically the same size and model, but
differ only in storage and network interfaces.
- eMMC (3W)
- SD-card (both)
- Ethernet (3E)
- WiFi/BT (3W)
This adds initial support for eMMC, SD-card, Ethernet, HDMI and USB.
