gallium: add lima driver
v2: - use renamed util_dynarray_grow_cap - use DEBUG_GET_ONCE_FLAGS_OPTION for debug flags - remove DRM_FORMAT_MOD_ARM_AGTB_MODE0 usage - compute min/max index in driver v3: - fix plbu framebuffer state calculation - fix color_16pc assemble - use nir_lower_all_source_mods for lowering neg/abs/sat - use float arrary for static GPU data - add disassemble comment for static shader code - use drm_find_modifier v4: - use lima_nir_lower_uniform_to_scalar v5: - remove nir_opt_global_to_local when rebase Cc: Rob Clark <[email protected]> Cc: Alyssa Rosenzweig <[email protected]> Acked-by: Eric Anholt <[email protected]> Signed-off-by: Andreas Baierl <[email protected]> Signed-off-by: Arno Messiaen <[email protected]> Signed-off-by: Connor Abbott <[email protected]> Signed-off-by: Erico Nunes <[email protected]> Signed-off-by: Heiko Stuebner <[email protected]> Signed-off-by: Koen Kooi <[email protected]> Signed-off-by: Marek Vasut <[email protected]> Signed-off-by: marmeladema <[email protected]> Signed-off-by: PaweÅ‚ Chmiel <[email protected]> Signed-off-by: Rob Herring <[email protected]> Signed-off-by: Rohan Garg <[email protected]> Signed-off-by: Vasily Khoruzhick <[email protected]> Signed-off-by: Qiang Yu <[email protected]>
