Add support for UHS-I modes by adding voltage regulator device tree nodes and corresponding pinmux details, to power cycle and voltage switch cards. Set respective tags in sdhci0 and remove no-1-8-v tag from sdhci1 device tree nodes. Also update the delay values for various speed modes supported, based on the latest J7200 datasheet[2] [1] - section 12.3.6.1.1 MMCSD Features, in https://www.ti.com/lit/ug/spruiu1a/spruiu1a.pdf [2] - https://www.ti.com/lit/ds/symlink/dra821a.pdf Signed-off-by: Aswath Govindraju <a-govindraju@ti.com> --- .../dts/ti/k3-j7200-common-proc-board.dts | 42 +++++++++++++++++++ arch/arm64/boot/dts/ti/k3-j7200-main.dtsi | 14 ++++++- 2 files changed, 54 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/ti/k3-j7200-common-proc-board.dts b/arch/arm64/boot/dts/ti/k3-j7200-common-proc-board.dts index b493f939b09a..6f90c3b1cf45 100644 --- a/arch/arm64/boot/dts/ti/k3-j7200-common-proc-board.dts +++ b/arch/arm64/boot/dts/ti/k3-j7200-common-proc-board.dts @@ -16,6 +16,29 @@ stdout-path = "serial2:115200n8"; bootargs = "console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000"; }; + + vdd_mmc1: fixedregulator-sd { + compatible = "regulator-fixed"; + regulator-name = "vdd_mmc1"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + regulator-boot-on; + enable-active-high; + gpios = <&exp2 2 GPIO_ACTIVE_HIGH>; + }; + + vdd_sd_dv: gpio-regulator-vdd-sd-dv { + compatible = "regulator-gpio"; + regulator-name = "vdd_sd_dv"; + pinctrl-names = "default"; + pinctrl-0 = <&vdd_sd_dv_pins_default>; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <3300000>; + regulator-boot-on; + gpios = <&main_gpio0 55 GPIO_ACTIVE_HIGH>; + states = <1800000 0x0 + 3300000 0x1>; + }; }; &wkup_pmx0 { @@ -45,6 +68,13 @@ }; &main_pmx0 { + main_i2c0_pins_default: main-i2c0-pins-default { + pinctrl-single,pins = < + J721E_IOPAD(0xd4, PIN_INPUT_PULLUP, 0) /* (V3) I2C0_SCL */ + J721E_IOPAD(0xd8, PIN_INPUT_PULLUP, 0) /* (W2) I2C0_SDA */ + >; + }; + main_i2c1_pins_default: main-i2c1-pins-default { pinctrl-single,pins = < J721E_IOPAD(0xdc, PIN_INPUT_PULLUP, 3) /* (U3) ECAP0_IN_APWM_OUT.I2C1_SCL */ @@ -70,6 +100,12 @@ J721E_IOPAD(0x120, PIN_OUTPUT, 0) /* (T4) USB0_DRVVBUS */ >; }; + + vdd_sd_dv_pins_default: vdd_sd_dv_pins_default { + pinctrl-single,pins = < + J721E_IOPAD(0xd0, PIN_INPUT, 7) /* (T5) SPI0_D1.GPIO0_55 */ + >; + }; }; &wkup_uart0 { @@ -157,6 +193,10 @@ }; &main_i2c0 { + pinctrl-names = "default"; + pinctrl-0 = <&main_i2c0_pins_default>; + clock-frequency = <400000>; + exp1: gpio@20 { compatible = "ti,tca6416"; reg = <0x20>; @@ -206,6 +246,8 @@ /* SD card */ pinctrl-0 = <&main_mmc1_pins_default>; pinctrl-names = "default"; + vmmc-supply = <&vdd_mmc1>; + vqmmc-supply = <&vdd_sd_dv>; ti,driver-strength-ohm = <50>; disable-wp; }; diff --git a/arch/arm64/boot/dts/ti/k3-j7200-main.dtsi b/arch/arm64/boot/dts/ti/k3-j7200-main.dtsi index e60650a62b14..f86c493a44f1 100644 --- a/arch/arm64/boot/dts/ti/k3-j7200-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j7200-main.dtsi @@ -512,11 +512,16 @@ ti,otap-del-sel-mmc-hs = <0x0>; ti,otap-del-sel-ddr52 = <0x6>; ti,otap-del-sel-hs200 = <0x8>; - ti,otap-del-sel-hs400 = <0x0>; + ti,otap-del-sel-hs400 = <0x5>; + ti,itap-del-sel-legacy = <0x10>; + ti,itap-del-sel-mmc-hs = <0xa>; ti,strobe-sel = <0x77>; + ti,clkbuf-sel = <0x7>; ti,trm-icp = <0x8>; bus-width = <8>; mmc-ddr-1_8v; + mmc-hs200-1_8v; + mmc-hs400-1_8v; dma-coherent; }; @@ -534,7 +539,12 @@ ti,otap-del-sel-sdr50 = <0xc>; ti,otap-del-sel-sdr104 = <0x5>; ti,otap-del-sel-ddr50 = <0xc>; - no-1-8-v; + ti,itap-del-sel-legacy = <0x0>; + ti,itap-del-sel-sd-hs = <0x0>; + ti,itap-del-sel-sdr12 = <0x0>; + ti,itap-del-sel-sdr25 = <0x0>; + ti,clkbuf-sel = <0x7>; + ti,trm-icp = <0x8>; dma-coherent; }; -- 2.17.1
