Subject: [PATCH 3/3] MIPS: qi_lb60: Move MMC configuration to devicetree
Move the MMC configuration from the board C file to devicetree.
The 'power' GPIO was removed and instead the vmmc regulator is used,
to follow the changes introduced in the jz4740-mmc driver.
Signed-off-by: Paul Cercueil <paul@...pouillou.net>
