Document the optional properties for describing module resets, to support resetting display channels and LVDS encoders on R-Car Gen2 and Gen3. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- See "[v2,1/4] dt-bindings: clock: renesas: cpg-mssr: Document reset control support" (https://patchwork.kernel.org/patch/9536627/) for the format of a reset specifier in the Renesas CPG/MSSR case.
