Subject: [PATCH v3 0/5] drm/fsl-dcu: initialization fixes

Hi All,

This is an assortment of fixes which solve issues seen using an
external RGB converter and makes sure that pixel clock is only
on when really required.

Meng, could you test that on a LS1021a?

- add patch to no not transfer registers in mode_set_nofb
- add patch which only init fbdev if required
- remove disable unprepare pixel clock on module remove (already disabled
  in CRTC disable callback).
- remove unused label
