[PATCH 04/20] drm/amd/display: drop display_pipe_clocks.c.

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

 



From: Dave Airlie <airlied@xxxxxxxxxx>

This code isn't used at all in the kernel tree, perhaps it can wait to
be imported when it is. It also does a lot of floating point calcs,
so probably good to drop it until it's needed and we can ensure
proper fpu accessors.
