[v4,08/10] drm/arm: malidp: Use crtc->mode_valid() callback

Message ID 7d0011d2b6a3b9ff892373e59e20efa1990500e1.1495091280.git.joabreu@synopsys.com (mailing list archive)

Now that we have a callback to check if crtc supports a given mode
we can use it in malidp so that we restrict the number of probbed
modes to the ones we can actually display.

Also, remove the mode_fixup() callback as this is no longer needed
because mode_valid() will be called before.

NOTE: Not even compiled tested
