In order to be able to communicate with the 88e6341 switch some pins have to be repurposed as RGMII and SMI pins. This fixes ethernet support on system booted via a bootloader that has not already configured those pins (e.g. mainline u-boot, or vendor u-boot compiled without ethernet support). Signed-off-by: Remi Pommarel <repk@xxxxxxxxxxxx> --- This should be applied along with pinctrl fixes from https://lkml.org/lkml/2018/12/21/507 which have been merged in next branch of linux-pinctrl tree. --- arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts | 2 ++ arch/arm64/boot/dts/marvell/armada-37xx.dtsi | 5 +++++ 2 files changed, 7 insertions(+) diff --git a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts index 846003bb480c..b60897edc885 100644 --- a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts +++ b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts @@ -196,6 +196,8 @@ }; ð0 { + pinctrl-names = "default"; + pinctrl-0 = <&rgmii_pins>, <&smi_pins>; phy-mode = "rgmii-id"; status = "okay"; diff --git a/arch/arm64/boot/dts/marvell/armada-37xx.dtsi b/arch/arm64/boot/dts/marvell/armada-37xx.dtsi index e05594ea15fb..f61538910901 100644 --- a/arch/arm64/boot/dts/marvell/armada-37xx.dtsi +++ b/arch/arm64/boot/dts/marvell/armada-37xx.dtsi @@ -271,6 +271,11 @@ function = "mii"; }; + smi_pins: smi-pins { + groups = "smi"; + function = "smi"; + }; + sdio_pins: sdio-pins { groups = "sdio_sb"; function = "sdio"; -- 2.20.1
