Subject: [PATCH v16 0/5] drm/mediatek: Add MT8195 dp_intf driver

The dpi/dpintf driver and the added helper functions are required for
the DisplayPort driver to work.

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.
