[PATCH v2 2/6] media: pxa_camera: Drop the v4l2-clk clock register

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that mach-based PXA platforms are registering proper
fixed-rate clocks through the CCF, the v4l2-clk clock
is no longer required.

Drop this clock, so the driver no longer depends on the
legacy v4l2-clk API.
