From 94a924ca61f05e444a3f7b860b2720d81b391da6 Mon Sep 17 00:00:00 2001 From: Mugunthan V N Date: Fri, 7 Jun 2013 17:02:53 +0530 Subject: [PATCH] ARM: dts: AM33XX: Add pinmux configuration for CPSW to EVMsk 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 Signed-off-by: Benoit Cousson --- 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 2033a37c86ec..9e00eef9b74b 100644 --- a/arch/arm/boot/dts/am335x-evmsk.dts +++ b/arch/arm/boot/dts/am335x-evmsk.dts @@ -77,6 +77,86 @@ 0x19c 0x4 /* mcasp0_ahclkr.ecap2_in_pwm2_out MODE4 */ >; }; + + 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 { @@ -300,3 +380,15 @@ }; }; }; + +&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>; +}; -- GitLab
