This series is separated from [1] which is original from Guillaume. The display port driver is [2]. Changes for v16: 1. Separate input_2pixel and pixels_per_iter to other patches. 2. Remove function "mtk_dpi_matrix_sel" and color_fmt_trans_support in patch "Add YUV422 output support". 3. Drop patches which are accepted. Changes for v15: 1. Add a patch to remove support for output yuv422 for previous socs. 2. Only remain output format of reg888/yuv422 support for mt8195. 3. Adjust the order of patches. Changes for v14: 1. Separate a new binding patch to modify mediatek string format. 2. Use GENMASK(4, 0) for INT_MATRIX_SEL_MASK in patch "Add YUV422 output support" 3. Change kernel doc description of support_direct_pin. 4. Change to use pixels_per_iter to control quantity of transferred pixels per iterration. Changes for v13: 1. Change mediatek,mt8195-dp_intf to mediatek,mt8195-dp-intf. 2. Add kernel doc for mtk_dpi_conf. 3. Drop patch of tvd_pll enable. 4. Squash some color format transfer related patches. 5. Add new patch to support setting of direct connection to pins. 6. Change fix tag of "drm/mediatek: dpi: Only enable dpi after the bridge is enabled". Changes for v12: 1. Remove pll_gate. 2. Add more detailed commit message. 3. Separate tvd_clk patch and yuv422 output support from add dpintf support patch 4. Remove limit patch and use common driver codes to determine this. Changes for v11: 1. Rename ck_cg to pll_gate. 2. Add some commit message to clarify the modification reason. 3. Fix some driver order and modify for reviewers' comments.
