[PATCH 00/57] media: atomisp: Big power-management changes + lots of fixes

[Hans de Goede <hdegoede@redhat.com>]

Hi All,

Here is another set of patches resulting from my continued work
on cleaning up / improving the atomisp driver.

The main changes here are power-management related, divided
into 2 sets:

1. Move the pm of the core atomisp device to its own custom PM
   domain. We turn the ISP on/off through the P-Unit and when
   off the PCI subsystem resume method complains about the PCI
   config space not being reachable. Changing to a custom PM
   domain fixes the logs getting filled with PCI subsys errors
   on every open of a /dev/video# node

2. Except for devices shipped with Android as factory image,
   all the DSDTs I have seen have proper ACPI pm code for
   the sensors. So we really should be using ACPI pm for this.

   This series contains a lot of ov2680 patches, including
   reworking the controls (so that control changes can be
   delayed to stream on time instead of directly trying to do
   i2c writes to the turned off sensor). Basically modernizing
   the ov2680 driver a lot (there are still some atomisp-isms left).

   And then finally after all the ov2680 cleanups it moves
   the ov2680 code over to using runtime-pm + ACPI pm,
   dropping all the direct PMIC + clk poking done by the
   atomisp_gmin_platform code.

Besides that this also contains quite a few other fixes / cleanups
for things which I encountered during the way and it contains the
start of making the ov2722 driver work. With the changes present
in that driver I get a working (but very dark) stream. I expect
that once I add a proper exposure control this will start working
better.

Regards,

Hans
