From: Kevin Hilman <[email protected]>
This series is a cleanup/reorg/streamline of the core idle path.
The goal is to remove all device-specific idle management out of the
core idle path into device-specific code.
This series starts with some of the device-specific hacks currently in
the idle path, and also moves GPIO handling out of the core idle loop.
Eventually, all device-specific idle management should be done using
the runtime PM hooks of the driver for that device. Until then,
temporary hacks belong in the new omap3_device_[idle|resume] functions.
Note that for debug purposes, UART is still managed inside the
interrupt-disabled idle path. This is for debug purposes only so that
any panic/BUG code that gets triggered before the device resume code
is run will not crash the system. As soon as the new omap-serial
driver is converted to runtime PM, the UART management can be removed
from the idle path as well.
Patch 1 will be queued in my pm-next branch for .37 and patch 2 should
be incorporated into baseline for the GPIO hwmod conversion.
