[PATCH 0/8] Add low power hibernation support to cs35l41

[Charles Keepax]

This patch series adds support for the low power hibernation feature
on cs35l41. This allows the DSP memory to be retained whilst the
device enters a very low power state.

Patches 1-6 can happily be applied straight away and are mostly bug
fixes to set things up for the series specifically around getting the
cache handling corrected in the driver.

Patches 7,8 specifically will cause some very minor conflicts with
Lucas's currently outstanding work on the HDA version of cs35l41.
Whilst things will still build, this patch adds a test key function
his code will now have to call. If his patches are getting merged
first I will respin this series to update his code, he is currently on
holiday until the 12th of Jan, so if we want to wait for another spin
of those patches I can work with him to update them at that time. Or
alternatively we could just merge them all and I will do a quick fixup
patch at the end, since there is no build breakage.

Thanks,
Charles
