Hi,
This series changes the mode set sequence so that the clock and PLL
logic that was done in the *_crtc_mode_set() hooks is done before
disabling crtcs. This avoids having to restore the old configuration
in the case of failure, since the hardware was never touched.
The changes went through only light testing in a single platform. But I'd
like to get comments on the general approach sooner rather than later,
hence this RFC.
Thanks,
Ander
