- Refactoring of DMA and IOMMU code
. This patch series simplifies DMA mapping creation by avoiding looping all components to get dma device object, reduces code size by merging IOMMU and DMA code. - Enhance plane alpha and blend mode support . This patch series adds configurable plane and pixel blend mode support for Exynos5433 DECON device. - Fix color format setting of Mixer driver . This patch series fixes color format and range setting by splitting range and format. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJcB5QcAAoJEFc4NIkMQxK4SREP/RLc4pPHDYg5KsWC952BKYuQ iDCTygSkrT8hsp1k3/3xV6aN0DpaPSYUOkaLyBJ51xzNAOnxyqYvYWI9x+CXQ3ej dU/1gDqQHpbGbXr+qdKE081T9EgKkaayVucJ9pSs3W7dniZ/t6GJK8yG4XlydXxe nk3l2X/FFMT0e7PMeD06trnLHFOerp95dDC63QNyNcojTTV2lq2qYG//9MNy8x39 Mz20HwF+Rus46stYimScMFtJozxdeBxky/GneXdRTeiaJrO7wNBF1FcyZ7BmA8fr NSTyg4VKNdPm3RPSmZxHOVikScKo/m2SGhCTA+4SeAmSdUk0Xk1/xRG5PGHNHMIE MWXAvk3P8BcYCOYau8KlCR0Ist97DU3f62kAKY1IO9w3vT3tJ7ihEX8pUKWVQuyl m7RXwKz9iMUl3T6JKj3XGalN24Oe4GY5M6kCjebq6iFQ9Vic2m+tiRHajcH07tMK svZChqIv0OiBkNIBRIUiobhqLWo4vPJrO8hf5ZWB50oHF/JWgMMd9/g/4NdL0oAq xUdkAFGFrX8H+JJztnsgMAM46dVSg1hJSe01mjckk5R0mz5TWZact2QhsVhcYCXM gP8la9RL59FCIk7RLa8c+TnH544r27I/XXuqTaiuRPcWqs68CBBax7dtB025hq1d ClKw6SZDsbodjEEj9I7m =NeIE -----END PGP SIGNATURE----- Merge tag 'exynos-drm-next-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next - Refactoring of DMA and IOMMU code .
