Allocate DSI host structure for each DSI port available on gen11 and register them with DSI fwk of DRM. Some of the DSI host operations are also registered as part of this. Retrieves DSI pkt (from DSI msg) to be sent over DSI link using DRM DSI exported functions. A wrapper function is also added as "DSI host transfer" for sending DSI data/cmd.

Imre Deak authored
The requirement for the DDI port clock gating for a port in DSI mode is the opposite wrt. the case when the port is in DDI mode: the clock should be gated when the port is active and ungated when the port is inactive. Note that we cannot simply keep the DDI clock gated when the port will be only used in DSI mode: it must be gated/ungated at a specific spot in the DSI enable/disable sequence. Ensure the above for all ports of a DSI encoder, also adding a sanity check that we haven't registered another encoder using the same port (VBT should never allow this to happen).

Unclutter the haswell_crtc_enable() and haswell_crtc_disable() functions a bit by moving the pll to port mapping and unmapping functions to the ddi encoder hooks. This allows removal of a bunch of boilerplate code from the functions. Additionally, the ICL DSI encoder needs to do the clock gating and ungating slightly differently, and this allows its own handling in a clean fashion.

As stated in struct drm_encoder, crtc field should only be used by non-atomic drivers. So here caching the pipe id in intel_psr_enable() what is way more simple and efficient than at every call to intel_psr_flush()/invalidate() get the drm.mode_config.connection_mutex lock to safely be able to get the pipe id by reading drm_connector_state.crtc. This should fix the null pointer dereference crash below as the previous way to get the pipe id was prone to race conditions.

Basic DSC parameters and DSC configuration data needs to be computed for each of the requested mode during atomic check. This is required since for certain modes, valid DSC parameters and config data might not be computed in which case compression cannot be enabled for that mode.
