[PATCH 0/5] Add R8A77980/Condor LVDS/HDMI support

[PATCH 0/5] Add R8A77980/Condor LVDS/HDMI support

[Sergei Shtylyov]

Hello!

Reposting with the correct subject... Sorry! :-]

Here's the set of 5 patches against Simon Horman's 'renesas.git' repo's
'renesas-devel-20180604-v4.17-rc7' tag. We're adding the R8A77980 FCPVD/VSPD/
DU/LVDS device nodes and then describing the LVDS decoder and HDMI encoder
connected to the LVDS output. These patches depend on the Thine THC63LVD1024
driver and the R8A77980 LVDS support patch in order to work, and R8A77980 GPIO
DT patches in order to apply/compile...

[1/5] arm64: dts: renesas: r8a77980: add FCPVD support
[2/5] arm64: dts: renesas: r8a77980: add VSPD support
[3/5] arm64: dts: renesas: r8a77980: add DU support
[4/5] arm64: dts: renesas: r8a77980: add LVDS support
[5/5] arm64: dts: renesas: condor: add DU/LVDS/HDMI support

WBR, Sergei

[PATCH 1/5] arm64: dts: renesas: r8a77980: add FCPVD support

[Sergei Shtylyov]

Describe FCPVD0 in the R8A77980 device tree; it will be used by VSPD0 in
the next patch...

Based on the original (and large) patch by Vladimir Barinov.
