2022-03-03drm: rcar-du: Drop LVDS device tree backward compatibilityLaurent Pinchart1-43/+0
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.

2019-01-14drm: rcar-du: Convert live DT patches to sugar syntaxGeert Uytterhoeven1-30/+23
Using overlay sugar syntax makes the DTS files easier to read (and write). Overlay syntactic sugar for generating target-path fragments is supported by the version of dtc supplied with the kernel since commit 50aafd60898a8b3e ("scripts/dtc: Update to upstream version v1.4.6-21-g84e414b0b5bc").

2018-03-07drm: rcar-du: Fix legacy DT to create LVDS encoder nodesLaurent Pinchart1-0/+50
The internal LVDS encoders now have their own DT bindings. Before switching the driver infrastructure to those new bindings, implement backward-compatibility through live DT patching. Patching is disabled and will be enabled along with support for the new DT bindings in the DU driver.
