Merge branch 'for-linus-sa1100' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM SA1100 updates from Russell King: "We have support for arbitary MMIO registers providing platform GPIOs, which allows us to abstract some of the SA11x0 CF support. This set of updates makes that change" * 'for-linus-sa1100' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: sa1100/simpad: switch simpad CF to use gpiod APIs ARM: sa1100/shannon: convert to generic CF sockets ARM: sa1100/nanoengine: convert to generic CF sockets ARM: sa1100/h3xxx: switch h3xxx PCMCIA to use gpiod APIs ARM: sa1100/cerf: convert to generic CF sockets ARM: sa1100/assabet: convert to generic CF sockets ARM: sa1100: provide infrastructure to support generic CF sockets pcmcia: sa1100: provide generic CF support
