Also add entry for pinmux information. Tested: 1) Without GPIO card detection and EDMA support as DT support for GPIO and EDMA are yet come. 2) By creating/deleting files and mounting/unmounting the partition.

Since v1: Removed bitfields for specifying the device capabilty and accomodate controller revision in compatible field. arch/arm/boot/dts/da850-evm.dts | 7 +++++++ arch/arm/boot/dts/da850.dtsi | 14 ++++++++++++++ 2 files changed, 21 insertions(+), 0 deletions(-) diff --git a/arch/arm/boot/dts/da850-evm.dts b/arch/arm/boot/dts/da850-evm.dts index f712fb6..78c8e54 100644 --- a/arch/arm/boot/dts/da850-evm.dts +++ b/arch/arm/boot/dts/da850-evm.dts @@ -39,6 +39,13 @@ wdt: wdt@1c21000 { status = "okay"; }; + mmc0: mmc@1c40000 { + max-frequency = <50000000>; + bus-width = <4>; + status = "okay"; + pinctrl-names = "default"; + pinctrl-0 = <&mmc0_pins>; + }; }; nand_cs3@62000000 { status = "okay"; diff --git a/arch/arm/boot/dts/da850.dtsi b/arch/arm/boot/dts/da850.dtsi index 4b2262a..ebe7386 100644 --- a/arch/arm/boot/dts/da850.dtsi +++ b/arch/arm/boot/dts/da850.dtsi @@ -67,6 +67,15 @@ 0x10 0x00002200 0x0000ff00 >; }; + mmc0_pins: pinmux_mmc_pins { + pinctrl-single,bits = < + /* MMCSD0_DAT[3] MMCSD0_DAT[2] + * MMCSD0_DAT[1] MMCSD0_DAT[0] + * MMCSD0_CMD MMCSD0_CLK + */ + 0x28 0x00222222 0x00ffffff + >; + }; }; serial0: serial@1c42000 { compatible = "ns16550a"; @@ -110,6 +119,11 @@ wdt: wdt@1c21000 { compatible = "ti,davinci-wdt"; reg = <0x21000 0x1000>; + }; + mmc0: mmc@1c40000 { + compatible = "ti,davinci-mmc-da830"; + reg = <0x40000 0x1000>; + interrupts = <16>; status = "disabled"; }; }; -- 1.7.4.1
