Landed in mainline as 732e8ee0351c on 2021-09-28.
Describe all Ethernet PHY reset GPIOs on R-Car Gen3 boards, to avoid relying solely on boot loaders to bring PHYs out of reset. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- This assumes the CPLD on v3hsk takes care of the PHY reset, like it is documented to do on v3msk. --- arch/arm64/boot/dts/renesas/draak.dtsi | 1 + arch/arm64/boot/dts/renesas/r8a77970-eagle.dts | 1 + arch/arm64/boot/dts/renesas/r8a77970-v3msk.dts | 2 ++ arch/arm64/boot/dts/renesas/r8a77980-condor.dts | 2 ++ arch/arm64/boot/dts/renesas/r8a77980-v3hsk.dts | 2 ++ 5 files changed, 8 insertions(+)
