On sun7i-a20-* there's no way to enable PA00--PA27 as RGB888 LCD0 pins.
Add lcd_rgb888_pins in sun7i-a20.dtsi.
It can be used on sun7i-a20-olinuxino-lime.dts.
This patch gives possibility to set parallel lcd pins for RGB888.
To be used with tcon0 in your <target>.dts

My question was on which board do you want to use it right now. If the
answer is none, then we won't merge that patch, we have too many
pinctrl already to not add the unused ones.

Board could be any with A20,
for example Olinuxino A20.
Or our Q027, S027 boards, but final dts still are not complete.

Therefore no upstream boards are using it right now, so we'll merge it
when that will be the case.

I think the LCD connector on Banana Pi's uses parallel interface,
although the LCD should be an external DT overlay.

This isn't a cover letter, but a commit log. You should document why
and how you did that change, nothing else.
On what board is this supposed to be used?
