[PATCH v2 0/4] drm/dp: Rework LTTPR transparent mode handling and add support to msm driver
Looking at both i915 and nouveau DP drivers, both are setting the first
LTTPR (if found) in transparent mode first and then in non-transparent
mode, just like the DP v2.0 specification mentions in section 3.6.6.1.
Being part of the standard, setting the LTTPR in a specific operation mode
can be easily moved in the generic framework. So do that by adding a new
helper.
Then, the msm DP driver is
