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. These patches will cause some very minor conflicts with Lucas's currently outstanding work on the HDA version of cs35l41. Whilst things will still build (well now I fixed my silly mistake), this patch adds a test key function his code will now have to call. It looks like Lucas's patch might get a respin based on the comments from Andy, in which case I guess we can pull the small change into the next version of it. But either way these patches are not urgent so I am happy if they sit around until Lucas's stuff is merged too.
