[PATCH v3 0/3] drm/omapdrm: gamma table support

[Jyri Sarha]

Implements gamma tables for OMAP4, OMAP5, and dra7xx SoCs and adds a
work-a-round for errata that may break LCD1 channel if gamma tables
are in use.

Changes from v2 to v3
- "drm/omapdrm: Add gamma table support to DSS dispc"
  - fix dispc_init_gamma_tables() to always return an int
  - omap54xx_dispc_feats initializes .has_gamma_table not .has_gamma_tables
- "drm/omapdrm: Work-a-round for errata i734 (LCD1 Gamma) in DSS dispc"
  - work-a-round -> workaround
  - Do not mention LOADMODE in description
  - dma_alloc_writecombine returns NULL on error
  - fix last wrong instrance of LCD output gating register
  - improve comment for framedone busy wait
  - add {} around busy loop's while statement

Changes from v1 to v2
- Drop "drm/omapdrm: omap_modeset_init: Separate crtc id and plane id indexing"
- "drm/omapdrm: Add gamma table support to DSS dispc"
 - Address Tomi's comments here: https://patchwork.kernel.org/patch/9128629/
- "drm/omapdrm: Work-a-round for errata i734 (LCD1 Gamma) in DSS dispc"
 - Address Tomi's comments here: https://patchwork.kernel.org/patch/9128633/
