[ARM] 3093/1: SharpSL PCMCIA Updates for Cxx00 models
Patch from Richard Purdie The Sharp SL-Cxx00 models have a combined power control for the SD and CF slot 0. This patch adds hooks to the scoop driver to allow machines to provide a custom control function for this and such a function is added for spitz/akita/borzoi. It also moves the gpio init code into the machine files as this is machine dependent and differs between some models. A couple of warnings when compiling for collie are also fixed. Signed-off-by: Richard Purdie Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
