The PHY initialisation parameters are not based on the pixel clock but the TMDS clock rate which can be the pixel clock in the standard case, but could be adjusted based on some parameters like the bits per color.

drm_atomic_helper_connector_reset uses kmalloc which, from an API standpoint, can fail, and thus setting connector->state to NULL. However, our reset hook then calls drm_atomic_helper_connector_tv_reset that will access connector->state without checking if it's a valid pointer or not.

Commit 63495f6b ("drm/vc4: hdmi: Make sure our clock rate is within limits") was intended to compute the pixel rate to make sure we remain within the boundaries of what the hardware can provide.

Panel drivers can send DSI commands in panel's prepare(), which happens before the bridge's enable() is called. The OMAP DSI driver currently only sets up the DSI interface at bridge's enable(), so prepare() cannot be used to send DSI commands. This patch fixes the issue by making it possible to enable the DSI interface any time a command is about to be sent. Disabling the interface is be done via delayed work. Clarifications for the delayed disable work and the panel doing DSI transactions: bridge_enable: If the disable callback is called just before bridge_enable takes the dsi_bus_lock, no problem, bridge_enable just enables the interface again. If the callback is ran just after bridge_enable's dsi_bus_unlock, no problem, dsi->video_enabled == true so the callback does nothing. bridge_disable: similar to bridge-enable, the callback won't do anything if video_enabled == true, and after bridge-disable has turned the video and the interface off, there's nothing to do for the callback. omap_dsi_host_detach: this is called when the panel does mipi_dsi_detach(), and we expect the panel to _not_ do any DSI transactions after (or during) mipi_dsi_detatch(), so there are no race conditions.

ULPS is a niche power-saving feature which only really affects command mode panels showing a static picture. I know the ULPS code used to work very long time ago, but I could not get it working with the current driver. As the ULPS code is not trivial and includes delayed work (so lots of chances for race issues), and just keeping DSI video and command mode panels working has been challenging enough even without ULPS, lets remove ULPS support. When the DSI driver works reliably for command and video mode displays, someone interested can work on ULPS and add it back if the power saving is substantial enough.
