Subject: [PATCH] omap_hsmmc: move gpio and regulator control from board file
This patch moves the setup code for GPIO's and Voltage
Regulators from the board file mmc-twl4030.c to the
driver omap_hsmmc.c.
Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined. That makes the
board initialisation now entirely independent of its original
twl4030 roots.
Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code. It also
permits the MMC core to be compiled as a module, because the
board code no longer calls MMC core functions.

NAK, we don't want to export omap_ctrl_read/write. That will
lead into a horrible mess again of all the drivers tinkering
with the omap hardware registers directly.
OK
All code like that needs to stay under mach-omap2. This same
mmc controller could in theory be used on other hardware too,
not just omaps. The ctrl registers are omap specific, not
mmc controller specific.

Tony
