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/
