From: Chris Morgan <macromor...@hotmail.com>
The Allwinner H616 and related SOCs have an LCD timing controller
(TCON) which is compatible with the R40 SOC's controller and existing
sun4i driver. The H616 does not expose this controller but the H700 and
T507 (based on the same die) do. The controller supports LVDS and RGB
output.
Add quirks and compatible string to cover these SOCs.
