The node configuration for mmc1 is missing, so add an mmc1 node in the device tree so add the basic node, set it to default it to disabled. Also add the vmmc and also the necessary slot configuration if this node where to be enabled to avoid the following warnings from the driver. atmel_mci f8000000.mmc: No vmmc regulator found atmel_mci f8000000.mmc: No vqmmc regulator found Signed-off-by: Ben Dooks -- CC: linux-arm-kernel at lists.infradead.org CC: Andrew Victor CC: Nicolas Ferre CC: Jean-Christophe Plagniol-Villard CC: Rob Herring CC: Pawel Moll CC: Mark Rutland CC: Ian Campbell CC: Kumar Gala CC: Russell King CC: linux-arm-kernel at lists.infradead.org CC: devicetree at vger.kernel.org --- arch/arm/boot/dts/at91-sama5d3_xplained.dts | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/arch/arm/boot/dts/at91-sama5d3_xplained.dts b/arch/arm/boot/dts/at91-sama5d3_xplained.dts index fec1fca..652c4dd 100644 --- a/arch/arm/boot/dts/at91-sama5d3_xplained.dts +++ b/arch/arm/boot/dts/at91-sama5d3_xplained.dts @@ -43,6 +43,17 @@ }; }; + mmc1: mmc at f8000000 { + vmmc-supply = <&vcc_3v3_reg>; + vqmmc-supply = <&vcc_3v3_reg>; + status = "disabled"; + slot at 0 { + reg = <0>; + bus-width = <4>; + cd-gpios = <&pioE 1 GPIO_ACTIVE_LOW>; + }; + }; + spi0: spi at f0004000 { cs-gpios = <&pioD 13 0>, <0>, <0>, <&pioD 16 0>; status = "okay"; -- 2.1.4
