We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.

PPI handling is a bit of an odd beast. It uses its own low level
handling code and is hardwired to the local timers (hence lacking
a registration interface).
Instead, switch the low handling to the normal SPI handling code.
PPIs are handled by the handle_percpu_devid_irq flow.
This also allows the removal of some duplicated code.

Remove OMAP4_USBC1_ICUSB_PWRDNZ_MASK during enable/disable PWRDNZ mode for

with the control module programming guide. This fixes a bug where if trying to
use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be
affected by a changing SDMMC1_VDDS.
Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever
SDMMC1_VDDS ramps up/down or changes for cell protection purposes.
MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore

Active sidetone requires that McBSP interface clock doesn't idle and there
is no mechanism in hwmod to turn autoidling on/off in runtime. McBSP2 and 3
in OMAP34xx share their interface clock with McBSP sidetone module and
that interface clock must be active when the sidetone is operating.
Sidetone has its own autoidle bit which should keep the interface clock
active but it is broken. Putting the McBSP core to no-idle mode when the
sidetone is active is no good either since it results to higher power
consumption when using the threshold based DMA transfers.
For making the McBSP code more generic, move this sidetone clock management
with fixme comments to mach-omap2/mcbsp.c and pass pointer to it via
platform data.
