[PATCH 00/17] amba: PM fixups for amba bus and some amba drivers

From: Ulf Hansson
Date: Tue Feb 04 2014 - 10:59:29 EST


This patchset fixes the PM problems you yet when combining CONFIG_PM_SLEEP and
CONFIG_PM_RUNTIME. In principle these drivers did not manage to put it's devices
into low power state at system suspend, which then this patchset intend to fix.

Both the drivers and the amba bus converts to the new SET_PM_RUNTIME_PM_OPS
macro while setting up the runtime PM callbacks, which is intended to be used
for solving these kind of issues.

The fixes for the amba bus needs to be merged prior to the other, thus I think
it could make sense to merge this complete patchset through Russell's tree,
if he and the other maintainers think this is okay.

Ulf Hansson (17):
amba: Let runtime PM callbacks be available for CONFIG_PM
amba: Add late and early PM callbacks
mmc: mmci: Mask IRQs for all variants during runtime suspend

mmc: mmci: Put the device into low power state at system suspend
spi: pl022: Let runtime PM callbacks be available for CONFIG_PM
spi: pl022: Don't ignore power domain and amba bus at system suspend
spi: pl022: Fully gate clocks at request inactivity
spi: pl022: Simplify clock handling

i2c: nomadik: Convert to devm functions
i2c: nomadik: Remove redundant call to pm_runtime_disable
i2c: nomadik: Leave probe with the device in active state
i2c: nomadik: Fixup deployment of runtime PM
i2c: nomadik: Convert to late and early system PM callbacks
