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.

2021-08-26device/mipi: Move to drivers/mipiJulius Werner
Sounds like we prefer to have this under drivers/ instead of device/. Also move all MIPI-related headers out from device/ into their own directory.
