[PATCH v3 00/11] drm/tilcdc: LCDC Revision 1 related fixes

[Jyri Sarha]

The git branch bellow is updated.

Changes since v2:
- Add: "drm/tilcdc: Fix load mode bit-field setting in tilcdc_crtc_enable()"
- Drop: "drm/tilcdc: Free palette dma memory in tilcdc_crtc_destroy()"
- Add: "drm/tilcdc: Add timeout wait for palette loading to complete"
- Add: "drm/tilcdc: Call reset() before loading the palette"
- Add: "drm/tilcdc: Use complete_all() to indicate completed palette loading"
- Add "drm/tilcdc: Enable frame done irq and functionality for LCDC rev 1"
  - Bartosz: Please test if this works! The symptom for not working is
    "timeout waiting for framedone" message when screen is blanked.

Changes since first version of the series:

- Move tilcdc_regs.h changes from "drm/tilcdc: Enable palette loading
  for revision 2 LCDC too" to "drm/tilcdc: Add tilcdc_write_mask() to
  tilcdc_regs.h"

These patches are inspired by this series form Bartosz Golaszewski:
https://www.spinics.net/lists/arm-kernel/msg539629.html

The patches are based on drm-next plus the earlier patches that I plan
to send in a pull request for 4.10. The base + these patches are
pushed here:
