[why] MST topology print was missing fec logging and pdt printed as an int wasn't clear. vcpi and payload info was printed as an arbitrary series of ints which requires user to know the ordering of the prints, making the logs difficult to use. [how] -add fec logging -add pdt parsing into strings -format vcpi and payload info into tables with headings -clean up topology prints Reviewed-by:

An old patch added a 'return' statement after each BUG() in this driver, which was necessary at the time, but has become redundant after the BUG() definition was updated to handle this properly. gcc-11 now warns about one such instance, where the 'return' statement was incorrectly indented: drivers/gpu/drm/omapdrm/dss/dispc.c: In function ‘pixinc’: drivers/gpu/drm/omapdrm/dss/dispc.c:2093:9: error: this ‘else’ clause does not guard... [-Werror=misleading-indentation] 2093 | else | ^~~~ drivers/gpu/drm/omapdrm/dss/dispc.c:2095:17: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘else’ 2095 | return 0; | ^~~~~~ Address this by removing the return again and changing the BUG() to be unconditional to make this more intuitive.

The tilcdc_pclk_diff() compares the requested pixel clock rate to the real one, so passing it clk_rate instead of clk_rate / clkdiv caused it to fail even if the clk_rate was properly set. Adding the real_pclk_rate variable makes the code more readable. Signed-off-by:

Just another issue I noticed while correcting usages of drm_dp_aux_init()/drm_dp_aux_register() around the tree. If any of the steps in anx78xx_bridge_attach() fail, we end up leaking resources. So, let's fix that (and fix leaking a DP AUX adapter in the process) by unrolling on errors. Signed-off-by:

Since encoder mappings for connectors are exposed to userspace, we should be attaching the encoder before exposing the connector to userspace. Just a drive-by fix for an issue I noticed while fixing up usages of drm_dp_aux_init()/drm_dp_aux_register() across the tree. Signed-off-by:

Surprisingly, this bridge actually registers it's AUX adapter at the correct time already. Nice job! However, it does forget to actually unregister the AUX adapter, so let's add a bridge function to handle that. Signed-off-by:

Lyude Paul authored
Since we're about to add a back-pointer to drm_dev in drm_dp_aux, let's move the AUX adapter registration to the first point where we know which DRM device we'll be working with - when the drm_bridge is attached. Likewise, we unregister the AUX adapter on bridge detachment by adding a ti_sn_bridge_detach() callback. Signed-off-by:
-
Lyude Paul authored
Since this is a bridge, we don't start out with a respective DRM device. Likewise this means we don't have a connector, which also means that we should be following drm_dp_aux_register()'s documentation advice and not call drm_dp_aux_register() until we have a matching connector. Instead, call drm_dp_aux_init() in tc_probe() and wait until tc_bridge_attach() to register our AUX channel. We also add tc_bridge_detach() to handle unregistering the AUX adapter once the bridge has been disconnected. Signed-off-by:
