7ea7728387 drm/core: Change declaration for gamma_set. 
Change return value to int to propagate errors from gamma_set,
and remove start parameter. Updates always use the full size,
and some drivers even ignore the start parameter altogether.

This is needed for atomic drivers, where an atomic commit can
fail with -EINTR or -ENOMEM and should be restarted. This is already
and issue for drm_atomic_helper_legacy_set_gamma, which this patch
fixes up.

Changes since v1:
- Fix compiler warning. (Emil)
- Fix commit message (Daniel)

28a8194c12 drm/gma500/cdv: Add and hook up chip op for watermarks 
Add a callback hook to the chip ops struct to allow chips to have their
specific fifo watermark update function. Currently only cdv actually
tries to set wms based on crtc configuration but if/when the other chips
needs it we can attach a callback for them as well.

5ea75e0f05 drm/gma500: Add generic code for clock calculation 
This patch aims to unify the bits and pieces that are common (or similar
enough) for pll clock calculations. Nothing makes use of this code yet
That will come in later patches.
