[v2,0/6] Remove last users of v4l2-clk and remove v4l2-clk

Message

The V4L2 temporary clock helper API is used by just one last capture
driver, pxa-camera, which registers a dummy clock; and then by just
a few sensor drivers, consuming clocks through the v4l2-clk API.

It's possible to convert these few last users, and so remove
the v4l2-clk API, which hasn't been used for a few years.

The sensor drivers are already using the CCF API,
which v4l2-clk API uses as fallback.

To convert the pxa-camera driver, a fixed-rate clock
is registered for the mach-based platforms that still exist,
for mt9m111 to work (the only sensor that PXA currently
registers).


Ezequiel Garcia (6):
  media: mach-pxa: Register the camera sensor fixed-rate clock
  media: pxa_camera: Drop the v4l2-clk clock register
  media: ov9640: Use the generic clock framework
  media: mt9m111: Use the generic clock framework
  media: ov6650: Use the generic clock framework
  media: Remove the legacy v4l2-clk API
