This allows the driver to reset the PHY during probe and after system resume. On ULCB, the enable pin of the regulator providing PHY power is always pulled high, but the driver may still need to reset the PHY if this wasn't done by the bootloader before. Inspired by patches in the BSP for the individual Salvator-X/XS boards by Kazuya Mizuguchi. Signed-off-by: Geert Uytterhoeven --- Compile-tested only. v4: - No changes, v3: - Extract from series "[PATCH 0/4] ravb: Add PHY reset support", and incorporate in this series, - Move reset-gpios from the ethernet to the ethernet-phy node. --- arch/arm64/boot/dts/renesas/ulcb.dtsi | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/boot/dts/renesas/ulcb.dtsi b/arch/arm64/boot/dts/renesas/ulcb.dtsi index 0d85b315ce711c8f..be91016e0b48f196 100644 --- a/arch/arm64/boot/dts/renesas/ulcb.dtsi +++ b/arch/arm64/boot/dts/renesas/ulcb.dtsi @@ -154,6 +154,7 @@ reg = <0>; interrupt-parent = <&gpio2>; interrupts = <11 IRQ_TYPE_LEVEL_LOW>; + reset-gpios = <&gpio2 10 GPIO_ACTIVE_LOW>; }; }; -- 2.7.4
