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. - Input of dp_intf is two pixels per iteration. - Some register contents differ slightly between the two components.

The quantity of output for one iteration could be different for dpi and dp_intf. For dp_intf, it's 4 pixels for one iteration it's 1 pixel for one iteration for dpi. Therefore, we add a new config "pixels_per_iter" to control quantity of transferred pixels per iteration. Signed-off-by:

Dp_intf supports YUV422 as output format. 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. Signed-off-by:

The hardware design of dp_intf does not support input swap, so we add a bit of flexibility to support SoCs without swap_input support. We also add a warning message if the hardware is not supported and it needs to swap input. Signed-off-by:

Remove compatible “mediatek,mt8192-disp-rdma” from the driver and should use “mediatek,mt8183-disp-rdma” as fallback in 8192 DTS according to the mediatek,rdma.yaml. Signed-off-by:

In the dsi_enable function, mtk_dsi_rxtx_control is to pull up the MIPI signal operation. Before dsi_disable, MIPI should also be pulled down by writing a register instead of disabling dsi. If disable dsi without pulling the mipi signal low, the value of the register will still maintain the setting of the mipi signal being pulled high. After resume, even if the mipi signal is not pulled high, it will still be in the high state.

To comply with the panel sequence, hold the mipi signal to LP00 before the dcs cmds transmission, and pull the mipi signal high from LP00 to LP11 until the start of the dcs cmds transmission. The normal panel timing is : (1) pp1800 DC pull up (2) avdd & avee AC pull high (3) lcm_reset pull high -> pull low -> pull high (4) Pull MIPI signal high (LP11) -> initial code -> send video data (HS mode) The power-off sequence is reversed. If dsi is not in cmd mode, then dsi will pull the mipi signal high in the mtk_output_dsi_enable function. The delay in lane_ready func is the reaction time of dsi_rx after pulling up the mipi signal.

In order to match the changes of "Use the drm_panel_bridge API", the poweron/poweroff of dsi is extracted from enable/disable and defined as new funcs (atomic_pre_enable/atomic_post_disable). Since dsi_poweron is moved from dsi_enable to pre_enable function, in order to avoid poweron failure, the operation of dsi register fails to cause bus hang. Therefore, the protection mechanism is added to the dsi_enable function.
