Hi Guennadi, Thank you for the patch. On Friday 27 September 2013 10:02:57 Guennadi Liakhovetski wrote:
Add SDHI0 and MMCIF interfaces to armadillo800eva-reference with regulators and pin configurations. SDHI1 is not added yet, because the switch, that connects the interface either to an SD slot or to a WiFi SDIO card cannot be described in DT yet. Signed-off-by: Guennadi Liakhovetski <redacted>
