Some EtherAVB variants support internal clock delay configuration, which can add larger delays than the delays that are typically supported by the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps" properties). Historically, the EtherAVB driver configured these delays based on the "rgmii-*id" PHY mode. This was wrong, as these are meant solely for the PHY, not for the MAC. Hence properties were introduced for explicit configuration of these delays. Convert the R-Car Gen3 DTS files from the old to the new scheme: - Add default "renesas,rxc-delay-ps" and "renesas,txc-delay-ps" properties to the SoC .dtsi files, to be overridden by board files where needed, - Convert board files from "rgmii-*id" PHY modes to "rgmii", adding the appropriate "renesas,rxc-delay-ps" and/or "renesas,txc-delay-ps" overrides. Notes: - R-Car E3 and D3 do not support TX internal delay handling, - On R-Car D3, TX internal delay handling must always be enabled, hence this fixes a bug on Draak, - On R-Car V3H, RX internal delay handling must always be enabled. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- This depends on "[PATCH/RFC 3/5] ravb: Add support for explicit internal clock delay configuration" and must not be applied before that dependency has hit upstream. --- arch/arm64/boot/dts/renesas/r8a77951.dtsi | 2 ++ arch/arm64/boot/dts/renesas/r8a77960.dtsi | 2 ++ arch/arm64/boot/dts/renesas/r8a77961.dtsi | 2 ++ arch/arm64/boot/dts/renesas/r8a77965.dtsi | 2 ++ arch/arm64/boot/dts/renesas/r8a77970-eagle.dts | 3 ++- arch/arm64/boot/dts/renesas/r8a77970-v3msk.dts | 3 ++- arch/arm64/boot/dts/renesas/r8a77970.dtsi | 2 ++ arch/arm64/boot/dts/renesas/r8a77980.dtsi | 2 ++ arch/arm64/boot/dts/renesas/r8a77990.dtsi | 1 + arch/arm64/boot/dts/renesas/r8a77995.dtsi | 1 + arch/arm64/boot/dts/renesas/salvator-common.dtsi | 2 +- arch/arm64/boot/dts/renesas/ulcb.dtsi | 2 +- 12 files changed, 20 insertions(+), 4 deletions(-)
