2019-05-31drm/bridge: tc358767: clean-up link trainingTomi Valkeinen
The current link training code does unnecessary retry-loops, and does extra writes to the registers. It is easier to follow the flow and ensure it's similar to Toshiba's documentation if we deal with LT inside tc_main_link_enable() function. This patch adds tc_wait_link_training() which handles waiting for the LT phase to finish, and does the necessary LT register setups in tc_main_link_enable, without extra loops.

2019-05-31drm/bridge: tc358767: use more reliable seq when finishing LTTomi Valkeinen
At the end of the link training, two steps have to be taken: 1) tc358767's LT mode is disabled by a write to DP0_SRCCTRL, and 2) Remove LT flag in DPCD 0x102. Toshiba's documentation tells to first write the DPCD, then modify DP0_SRCCTRL. In my testing this often causes issues, and the link disconnects right after those steps. If I reverse the steps, it works every time. There's a chance that this is DP sink specific, though, but as my testing shows this sequence to be much more reliable, let's change it.

2019-05-31drm/bridge: tc358767: ensure DP is disabled before LTTomi Valkeinen
Link training will sometimes fail if the DP link is enabled when tc_main_link_enable() is called. The driver makes sure the DP link is disabled when the DP output is disabled, and we never enable the DP without first disabling it, so this should never happen. However, as the HW behavior seems to be somewhat random if DP link has erroneously been left enabled, let's add a WARN_ON() for the case and set DP0CTL to 0.
