2023-09-12drivers/mipi: sta_himax83102: Completely pull GPW to VGL before TP termRuihai Zhou
The sta_himax83102 panel sometimes shows abnormally flickering horizontal lines. The front gate output will precharge the X point of the next pole circuit before TP term starts, and wait until the end of the TP term to resume the CLK. For this reason, the X point must be maintained during the TP term. In abnormal case, we measured a slight leakage at point X. This is because during the TP term, the GPW does not fully pull the VGL low, causing the TFT to not be closed tightly. To fix this, we completely pull GPW to VGL before entering the TP term. This will ensure that the TFT is closed tightly and prevent the abnormal display.

2023-08-01drivers/mipi: sta_ili9882t: Change TReset-CMD from 1.1 ms to 20 msRuihai Zhou
In the datasheet of ILI9882T [1] section 3.11 Power On/Off Sequence, the TReset-CMD (Reset to First Command in Display Sleep In Mode) should be larger than 10ms, but it's 1.1ms now. This may cause abnormal display as some commands may be lost during power on. Fix this and leave some margins by increasing TReset-CMD to 20ms. Also, to align with the kernel driver structure starry_ili9882t_init_cmd, add 20ms delay at the end of command.

2023-07-20drivers/mipi: Modify INX_P110ZZD_DF0 panel initialization codeCong Yang
There is a problem of screen shake on the old panel[1]. So increase the panel GOP component pull-down circuit size in hardware, and update the initialization code at the same time. The new initialization code is mainly adjusted for GOP timing. When Display sleep in, raise all GOP signals to VGHO and then drop to GND. In order to be consistent with the current panel model, let's rename this file. [1]: INX old panel product number is HJ110IZ-01A-B1, and the new panel product number is HJ110IZ-01A-B2. We have recalled the shipment old panel.

2022-03-09commonlib/bsd: Remove cb_err_tJulius Werner
cb_err_t was meant to be used in place of `enum cb_err` in all situations, but the choice to use a typedef here seems to be controversial. We should not be arbitrarily using two different identifiers for the same thing across the codebase, so since there are no use cases for serializing enum cb_err at the moment (which would be the primary reason to typedef a fixed-width integer instead), remove cb_err_t again for now.

2021-09-11mipi: Make panel init callback work directly on DSI transaction typesJulius Werner
Our MIPI panel initialization framework differentiates between DCS and GENERIC commands, but the exact interpretation of those terms is left to the platform drivers. In practice, the MIPI DSI transaction codes for these are standardized and platforms always need to do the same operation of combining the command length and transfer type into a correct DSI protocol code. This patch factors out the various platform-specific DSI protocol definitions into a single global one and moves the transaction type calculation into the common panel framework. The Qualcomm SC7180 implementation which previously only supported DCS commands is enhanced to (hopefully? untested for now...) also support GENERIC commands. While we're rewriting that whole section also fix some other issues about how exactly long and short commands need to be passed to that hardware which we identified in the meantime.

2021-09-02drivers/mipi: Make orientation a property of the mainboard, not panelJulius Werner
It doesn't make sense to store the orientation field directly in the panel information structure, which is supposed to be reuseable between different boards. The thing that determines orientation is how that panel is built into the board in question, which only the board itself can know. The same portrait panel could be rotated left to be used as landscape in one board and rotated right to be used as landscape in another. This patch moves the orientation field out of the panel structure back into the mainboards to reflect this.
