Add rk3318 A95X Z2 board.
What works:
adc key
emmc
ethernet
hdmi
gpu
ir
mmc
sd card
vop
usb2
uart2
Not tested:
av
uart0 / bt
spdif
wifi
No support in mainline:
usb3 (works with manufacturer driver)
front display (works with custom gpio driver AD1628/HT1628)
Problems:
U-boot only starts on emmc, then loads kernel from sd card or emmc.
Hdmi hotplug detects DVI modes, but marks them all BAD.
The dw-hdmi driver needs more pre_pll_cfg_table entries.
Slow boot behavior. Screen available way after boot. (no penguins)
GPU support for Debian is not up to date. (old version)
Use Github version instead.
Test with glmark2-es2-drm gives glmark2 Score: 29
Kernel log:
lima ff300000.gpu: pp pp0 reset time out
lima ff300000.gpu: pp pp1 reset time out
No mainline support for GPU thermal and voltage to frequency.
PWM1 supply connected to DMC, GPU and vcodec.
The box only has a model name. Vendor prefix not verified.
Etc.
Changed V2:
add vendor prefix
changed compatible string
restyle
removed usb3 regulator node
changed led active high to active low
