In MT8195 Chrome project, YUV422 output format is used for 4K resolution. To support this, it is also needed to support color format transfer. Color format transfer is a new feature for both dpi and dpintf of MT8195. The input format could be RGB888 and output format for dp_intf should be YUV422. Therefore, we add a mtk_dpi_matrix_sel() helper to update the DPI_MATRIX_SET register depending on the color format.

charset="utf-8" From: Guillaume Ranquet Dpintf is the displayport interface hardware unit. This unit is similar to dpi and can reuse most of the code. This patch adds support for mt8195-dpintf to this dpi driver. Main differences are: - 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one iteration. Therefore, we add a new config "pixels_per_iter" to control quantity of transferred pixels per iteration. - Input of dp_intf is two pixels per iteration, so we add a new config "input_2pixel" to control this. - Some register contents differ slightly between the two components. To work around this I added register bits/masks with a DPINTF_ prefix and use them where different. Based on a separate driver for dpintf created by Jitao shi .
