Subject: drm: rcar-du: Drop LVDS device tree backward compatibility
Git-commit: 841281fe52a769fedcf615880a33a2d0b2062b70
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The rcar-du driver goes to great lengths to preserve device tree
backward compatibility for the LVDS encoders by patching old device
trees at runtime.
The last R-Car Gen2 platform was converted to the new bindings commit
edb0c3affe5214a2 ("ARM: dts: r8a7793: Convert to new LVDS DT bindings"),
in v4.17, and the last RZ/G1 platform converted in commit
6a6a797625b5fe85 ("ARM: dts: r8a7743: Convert to new LVDS DT bindings"),
in v5.0. Both are older than commit 58256143cff7c2e0 ("clk: renesas:
Remove R-Car Gen2 legacy DT clock support"), in v5.5, which removes
support for legacy bindings for clocks. The LVDS compatibility code is
thus not needed anymore. Drop it.
