Subject: [RFC PATCH v1 0/2] rk3318 A95X Z2 board

status: EXPERIMENTAL
Use on your own risk.

What works:
 uart2
 mmc
 emmc
 sd card
 usb2

What doesn't work:
 vop
 hdmi
 ethernet

Not tested:
 adc key
 av
 bt
 ir
 spdif
 wifi

No support in mainline:
 usb3
 front display

Problems:
 U-boot only starts on emmc, then loads kernel from sd card.
 Need pd_ignore_unused and clk_ignore_unused in command line
 to prevent a crash. Missing power domains?
 Hdmi hotplug detects DVI modes, but marks them all BAD.
 A fixed display mode in the command line also gives no penguins
 on the screen.
 Etc.
