arm64: dts: amlogic: add support for Radxa Zero
Radxa Zero is a small form factor SBC based on the Amlogic S905Y2 chipset that ships in a number of RAM/eMMC configurations: Boards with 512MB/1GB LPDDR4 RAM have no eMMC storage and BCM43436 wireless (2.4GHz b/g/n) while 2GB/4GB boards have 8/16/32/64/128GB eMMC storage and BCM4345 wireless (2.4/5GHz a/b/g/n/ac). - Amlogic S905Y2 quad-core Cortex-A53 - Mali G31-MP2 GPU - HDMI 2.1 output (micro) - 1x USB 2.0 port - Type C (OTG) - 1x USB 3.0 port - Type C (Host) - 1x micro SD Card slot - 40 Pin GPIO header Signed-off-by: Christian Hewitt <christianshewitt@gmail.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://lore.kernel.org/r/20210909102154.22710-3-christianshewitt@gmail.com
