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"
