2022-03-03drm: rcar-du: Drop LVDS device tree backward compatibilityLaurent Pinchart
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.

2018-05-17drm: rcar-du: Fix rcar_du_of_init() stubLaurent Pinchart
The rcar_du_of_init() function is supposed to be defined as a stub when CONFIG_DRM_RCAR_LVDS is disabled as the rcar_du_of.c file isn't compiled in that case. However, a bug in the configuration option check makes it a stub when CONFIG_DRM_RCAR_LVDS=m as well, which prevents legacy DTs from being fixed at boot time. Fix the configuration option check by using IS_ENABLED.

2018-03-07drm: rcar-du: Fix legacy DT to create LVDS encoder nodesLaurent Pinchart
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.
