Robert's mailbox is bouncing, so let's add Daniel and Haojian. Could you guys review the PXA changes? Thanks, Ezequiel On Mon, 2021-01-04 at 13:57 -0300, Ezequiel Garcia wrote:
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).
