The mmc1 channel is not populated on the SAM5D3 Xplained board, however it is enabled and therefore the driver is attaching to it. 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 <ben.dooks@codethink.co.uk> -- CC: linux-arm-kernel@lists.infradead.org CC: Andrew Victor <linux@maxim.org.za> CC: Nicolas Ferre <nicolas.ferre@atmel.com> CC: Jean-Christophe Plagniol-Villard <plagnioj@jcrosoft.com> CC: Rob Herring <robh+dt@kernel.org> CC: Pawel Moll <pawel.moll@arm.com> CC: Mark Rutland <mark.rutland@arm.com> CC: Ian Campbell <ijc+devicetree@hellion.org.uk> CC: Kumar Gala <galak@codeaurora.org> CC: Russell King <linux@arm.linux.org.uk> CC: linux-arm-kernel@lists.infradead.org CC: devicetree@vger.kernel.org --- arch/arm/boot/dts/at91-sama5d3_xplained.dts | 11 +++++++++++ 1 file changed, 11 insertions(+)
