Add pinmux configurations for RGMII based CPSW ethernet to AM335x EVMsk. Default mode is nothing but the values required for the module during active state. With this configurations module is functional as expected.
Sleep mode is nothing but the values required for the module during inactive state. The pins are configured to its reset state to optimize energy usage for the pins for the suspend/resume cycle Signed-off-by: Mugunthan V N <[email protected]> --- arch/arm/boot/dts/am335x-evmsk.dts | 92 ++++++++++++++++++++++++++++++++++++ 1 file changed, 92 insertions(+) diff --git a/arch/arm/boot/dts/am335x-evmsk.dts b/arch/arm/boot/dts/am335x-evmsk.dts index 338b681..a0c201d 100644 --- a/arch/arm/boot/dts/am335x-evmsk.dts +++ b/arch/arm/boot/dts/am335x-evmsk.dts @@ -71,6 +71,86 @@ 0x1b4 (PIN_OUTPUT_PULLDOWN | MUX_MODE3) /* xdma_event_intr1.clkout2 */ >; }; + + cpsw_default: cpsw_default { + pinctrl-single,pins = < + /* Slave 1 */ + 0x114 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txen.rgmii1_tctl */ + 0x118 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxdv.rgmii1_rctl */ + 0x11c (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd3.rgmii1_td3 */ + 0x120 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd2.rgmii1_td2 */ + 0x124 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd1.rgmii1_td1 */ + 0x128 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txd0.rgmii1_td0 */ + 0x12c (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* mii1_txclk.rgmii1_tclk */ + 0x130 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxclk.rgmii1_rclk */ + 0x134 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd3.rgmii1_rd3 */ + 0x138 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd2.rgmii1_rd2 */ + 0x13c (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd1.rgmii1_rd1 */ + 0x140 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* mii1_rxd0.rgmii1_rd0 */ + + /* Slave 2 */ + 0x40 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* gpmc_a0.rgmii2_tctl */ + 0x44 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* gpmc_a1.rgmii2_rctl */ + 0x48 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* gpmc_a2.rgmii2_td3 */ + 0x4c (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* gpmc_a3.rgmii2_td2 */ + 0x50 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* gpmc_a4.rgmii2_td1 */ + 0x54 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* gpmc_a5.rgmii2_td0 */ + 0x58 (PIN_OUTPUT_PULLDOWN | MUX_MODE2) /* gpmc_a6.rgmii2_tclk */ + 0x5c (PIN_INPUT_PULLDOWN | MUX_MODE2) /* gpmc_a7.rgmii2_rclk */ + 0x60 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* gpmc_a8.rgmii2_rd3 */ + 0x64 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* gpmc_a9.rgmii2_rd2 */ + 0x68 (PIN_INPUT_PULLDOWN | MUX_MODE2) /* gpmc_a10.rgmii2_rd1 */ + 0x6c (PIN_INPUT_PULLDOWN | MUX_MODE2) /* gpmc_a11.rgmii2_rd0 */ + >; + }; + + cpsw_sleep: cpsw_sleep { + pinctrl-single,pins = < + /* Slave 1 reset value */ + 0x114 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x118 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x11c (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x120 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x124 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x128 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x12c (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x130 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x134 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x138 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x13c (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x140 (PIN_INPUT_PULLDOWN | MUX_MODE7) + + /* Slave 2 reset value*/ + 0x40 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x44 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x48 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x4c (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x50 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x54 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x58 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x5c (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x60 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x64 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x68 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x6c (PIN_INPUT_PULLDOWN | MUX_MODE7) + >; + }; + + davinci_mdio_default: davinci_mdio_default { + pinctrl-single,pins = < + /* MDIO */ + 0x148 (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE0) /* mdio_data.mdio_data */ + 0x14c (PIN_OUTPUT_PULLUP | MUX_MODE0) /* mdio_clk.mdio_clk */ + >; + }; + + davinci_mdio_sleep: davinci_mdio_sleep { + pinctrl-single,pins = < + /* MDIO reset value */ + 0x148 (PIN_INPUT_PULLDOWN | MUX_MODE7) + 0x14c (PIN_INPUT_PULLDOWN | MUX_MODE7) + >; + }; }; ocp { @@ -277,3 +357,15 @@ }; }; }; + +&mac { + pinctrl-names = "default", "sleep"; + pinctrl-0 = <&cpsw_default>; + pinctrl-1 = <&cpsw_sleep>; +}; + +&davinci_mdio { + pinctrl-names = "default", "sleep"; + pinctrl-0 = <&davinci_mdio_default>; + pinctrl-1 = <&davinci_mdio_sleep>; +}; -- 1.7.9.5 _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
