From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guennadi Liakhovetski Date: Mon, 23 Sep 2013 15:38:47 +0000 Subject: [PATCH/RFC v4] ARM: shmobile: armadillo800eva-reference: add SDHI and MMCIF interfaces Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org Add SDHI0, SDHI1 and MMCIF interfaces to armadillo800eva-reference with regulators and pin configurations. Signed-off-by: Guennadi Liakhovetski --- v4: 1. now that PFC pinctrl is usable with DT, we can use proper regulators and pin configurations on armadillo800eva 2. corrected SDHI compatibility strings 3. RFC because I don't know how to enable choosing between CON14 and CON8. In .c version this is done by reading GPIO 6. To do the same in DT mode we'd probably have to use some run-time DT patching, which isn't possible yet, AFAICS. .../boot/dts/r8a7740-armadillo800eva-reference.dts | 83 ++++++++++++++++++++ arch/arm/boot/dts/r8a7740.dtsi | 33 ++++++++ 2 files changed, 116 insertions(+), 0 deletions(-) diff --git a/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts b/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts index c638e4a..af15be0 100644 --- a/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts +++ b/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts @@ -34,6 +34,44 @@ regulator-boot-on; }; + vcc_sdhi0: regulator@1 { + compatible = "regulator-fixed"; + + regulator-name = "SDHI0 Vcc"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + + gpio = <&pfc 75 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; + + vcc_sdhi1: regulator@2 { + compatible = "regulator-fixed"; + + regulator-name = "SDHI1 Vcc"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + + gpio = <&pfc 16 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; + + vccq_sdhi0: regulator@3 { + compatible = "regulator-gpio"; + + regulator-name = "SDHI0 VccQ"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <3300000>; + vin-supply = <&vcc_sdhi0>; + + enable-gpio = <&pfc 74 GPIO_ACTIVE_HIGH>; + gpios = <&pfc 17 GPIO_ACTIVE_HIGH>; + states = <3300000 0 + 1800000 1>; + + enable-active-high; + }; + leds { compatible = "gpio-leds"; led1 { @@ -76,4 +114,49 @@ renesas,groups = "intc_irq10"; renesas,function = "intc"; }; + + mmc0_pins: mmc0 { + renesas,groups = "mmc0_data8_1", "mmc0_ctrl_1"; + renesas,function = "mmc0"; + }; + + sdhi0_pins: sdhi0 { + renesas,groups = "sdhi0_data4", "sdhi0_ctrl", "sdhi0_wp"; + renesas,function = "sdhi0"; + }; + + sdhi1_pins: sdhi1 { + renesas,groups = "sdhi1_data4", "sdhi1_ctrl", "sdhi1_cd", "sdhi1_wp"; + renesas,function = "sdhi1"; + }; +}; + +&mmcif0 { + pinctrl-0 = <&mmc0_pins>; + pinctrl-names = "default"; + + vmmc-supply = <®_3p3v>; + bus-width = <8>; + non-removable; + status = "okay"; +}; + +&sdhi0 { + pinctrl-0 = <&sdhi0_pins>; + pinctrl-names = "default"; + + vmmc-supply = <&vcc_sdhi0>; + vqmmc-supply = <&vccq_sdhi0>; + bus-width = <4>; + broken-cd; + status = "okay"; +}; + +&sdhi1 { + pinctrl-0 = <&sdhi1_pins>; + pinctrl-names = "default"; + + vmmc-supply = <&vcc_sdhi1>; + bus-width = <4>; + status = "okay"; }; diff --git a/arch/arm/boot/dts/r8a7740.dtsi b/arch/arm/boot/dts/r8a7740.dtsi index 44d3d52..018c02d 100644 --- a/arch/arm/boot/dts/r8a7740.dtsi +++ b/arch/arm/boot/dts/r8a7740.dtsi @@ -159,4 +159,37 @@ status = "disabled"; #pwm-cells = <3>; }; + + mmcif0: mmcif@e6bd0000 { + compatible = "renesas,sh-mmcif"; + reg = <0xe6bd0000 0x100>; + interrupt-parent = <&gic>; + interrupts = <0 56 4 + 0 57 4>; + status = "disabled"; + }; + + sdhi0: sdhi@e6850000 { + compatible = "renesas,sdhi-r8a7740"; + reg = <0xe6850000 0x100>; + interrupt-parent = <&gic>; + interrupts = <0 117 4 + 0 118 4 + 0 119 4>; + cap-sd-highspeed; + cap-sdio-irq; + status = "disabled"; + }; + + sdhi1: sdhi@e6860000 { + compatible = "renesas,sdhi-r8a7740"; + reg = <0xe6860000 0x100>; + interrupt-parent = <&gic>; + interrupts = <0 121 4 + 0 122 4 + 0 123 4>; + cap-sd-highspeed; + cap-sdio-irq; + status = "disabled"; + }; }; -- 1.7.2.5
