Subject: arm64: dts: renesas: Simplify AA1024XD12 display DTO
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5f10bbf91ea2e733ba8c5e88b1515217eb41c772;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: renesas: Simplify AA1024XD12 display DTO

Move all differences into panel-aa104xd12.dtsi, rename OF_GRAPH links to
generic lvds_panel_out and lvds_panel_in names, and parametrize the LVDS
output in use using RENESAS_LVDS_OUTPUT macro.  No functional change.
