From 4599bb7d79463da7e53b8920c759ad2a172ae2a5 Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Tue, 24 Jan 2023 11:43:27 +0200 Subject: [PATCH] arm: dts: k3-am64: Fix CPSW3G ethernet As MDIO driver does not support Driver Model, the pinctrl settings in the MDIO node will not be applied resulting in PHY not being detected. To workaround this we add the MDIO pinctrl in the CPSW3G node in the -u-boot.dtsi file. Add the missing MDIO and RGMII pinctrl nodes in k3-am642-r5-evm.dts Signed-off-by: Roger Quadros Reviewed-by: Tom Rini --- arch/arm/dts/k3-am642-evm-u-boot.dtsi | 3 ++ arch/arm/dts/k3-am642-r5-evm.dts | 41 +++++++++++++++++++++++++++ 2 files changed, 44 insertions(+) diff --git a/arch/arm/dts/k3-am642-evm-u-boot.dtsi b/arch/arm/dts/k3-am642-evm-u-boot.dtsi index fa7750d634..9b6c7e85cb 100644 --- a/arch/arm/dts/k3-am642-evm-u-boot.dtsi +++ b/arch/arm/dts/k3-am642-evm-u-boot.dtsi @@ -113,6 +113,9 @@ <0x0 0x43000200 0x0 0x8>; reg-names = "cpsw_nuss", "mac_efuse"; /delete-property/ ranges; + pinctrl-0 = <&mdio1_pins_default /* HACK: as MDIO driver is not DM enabled */ + &rgmii1_pins_default + &rgmii2_pins_default>; cpsw-phy-sel@04044 { compatible = "ti,am64-phy-gmii-sel"; diff --git a/arch/arm/dts/k3-am642-r5-evm.dts b/arch/arm/dts/k3-am642-r5-evm.dts index 92a6bfdc01..7493362ac6 100644 --- a/arch/arm/dts/k3-am642-r5-evm.dts +++ b/arch/arm/dts/k3-am642-r5-evm.dts @@ -167,6 +167,47 @@ AM64X_IOPAD(0x02a8, PIN_OUTPUT, 0) /* (E19) USB0_DRVVBUS */ >; }; + + mdio1_pins_default: mdio1-pins-default { + pinctrl-single,pins = < + AM64X_IOPAD(0x01fc, PIN_OUTPUT, 4) /* (R2) PRG0_PRU1_GPO19.MDIO0_MDC */ + AM64X_IOPAD(0x01f8, PIN_INPUT, 4) /* (P5) PRG0_PRU1_GPO18.MDIO0_MDIO */ + >; + }; + + rgmii1_pins_default: rgmii1-pins-default { + pinctrl-single,pins = < + AM64X_IOPAD(0x01cc, PIN_INPUT, 4) /* (W5) PRG0_PRU1_GPO7.RGMII1_RD0 */ + AM64X_IOPAD(0x01d4, PIN_INPUT, 4) /* (Y5) PRG0_PRU1_GPO9.RGMII1_RD1 */ + AM64X_IOPAD(0x01d8, PIN_INPUT, 4) /* (V6) PRG0_PRU1_GPO10.RGMII1_RD2 */ + AM64X_IOPAD(0x01f4, PIN_INPUT, 4) /* (V5) PRG0_PRU1_GPO17.RGMII1_RD3 */ + AM64X_IOPAD(0x0188, PIN_INPUT, 4) /* (AA5) PRG0_PRU0_GPO10.RGMII1_RXC */ + AM64X_IOPAD(0x0184, PIN_INPUT, 4) /* (W6) PRG0_PRU0_GPO9.RGMII1_RX_CTL */ + AM64X_IOPAD(0x0124, PIN_OUTPUT, 4) /* (V15) PRG1_PRU1_GPO7.RGMII1_TD0 */ + AM64X_IOPAD(0x012c, PIN_OUTPUT, 4) /* (V14) PRG1_PRU1_GPO9.RGMII1_TD1 */ + AM64X_IOPAD(0x0130, PIN_OUTPUT, 4) /* (W14) PRG1_PRU1_GPO10.RGMII1_TD2 */ + AM64X_IOPAD(0x014c, PIN_OUTPUT, 4) /* (AA14) PRG1_PRU1_GPO17.RGMII1_TD3 */ + AM64X_IOPAD(0x00e0, PIN_OUTPUT, 4) /* (U14) PRG1_PRU0_GPO10.RGMII1_TXC */ + AM64X_IOPAD(0x00dc, PIN_OUTPUT, 4) /* (U15) PRG1_PRU0_GPO9.RGMII1_TX_CTL */ + >; + }; + + rgmii2_pins_default: rgmii2-pins-default { + pinctrl-single,pins = < + AM64X_IOPAD(0x0108, PIN_INPUT, 4) /* (W11) PRG1_PRU1_GPO0.RGMII2_RD0 */ + AM64X_IOPAD(0x010c, PIN_INPUT, 4) /* (V11) PRG1_PRU1_GPO1.RGMII2_RD1 */ + AM64X_IOPAD(0x0110, PIN_INPUT, 4) /* (AA12) PRG1_PRU1_GPO2.RGMII2_RD2 */ + AM64X_IOPAD(0x0114, PIN_INPUT, 4) /* (Y12) PRG1_PRU1_GPO3.RGMII2_RD3 */ + AM64X_IOPAD(0x0120, PIN_INPUT, 4) /* (U11) PRG1_PRU1_GPO6.RGMII2_RXC */ + AM64X_IOPAD(0x0118, PIN_INPUT, 4) /* (W12) PRG1_PRU1_GPO4.RGMII2_RX_CTL */ + AM64X_IOPAD(0x0134, PIN_OUTPUT, 4) /* (AA10) PRG1_PRU1_GPO11.RGMII2_TD0 */ + AM64X_IOPAD(0x0138, PIN_OUTPUT, 4) /* (V10) PRG1_PRU1_GPO12.RGMII2_TD1 */ + AM64X_IOPAD(0x013c, PIN_OUTPUT, 4) /* (U10) PRG1_PRU1_GPO13.RGMII2_TD2 */ + AM64X_IOPAD(0x0140, PIN_OUTPUT, 4) /* (AA11) PRG1_PRU1_GPO14.RGMII2_TD3 */ + AM64X_IOPAD(0x0148, PIN_OUTPUT, 4) /* (Y10) PRG1_PRU1_GPO16.RGMII2_TXC */ + AM64X_IOPAD(0x0144, PIN_OUTPUT, 4) /* (Y11) PRG1_PRU1_GPO15.RGMII2_TX_CTL */ + >; + }; }; &dmsc { -- 2.39.5
