[PATCH 0/2] VRR Register Read/Write Updates

[Ankit Nautiyal]

Now that we have switched to VRR Timing generator from PTL onwards, we
no longer need to program VTOTAL.Vtotal bits, which were used by Legacy
Timing Generator.
This patch series is a continuation from discussion of another patch for
avoid reading/writing VTOTAL.Vtotal bits [1].
First patch introduces a macro to exclude DSI transcoded from VRR
programming in a consistent manner. The next patch actually modifies
reading/writing VTOTAL register.

Rev2: Address comments from Ville.
Rev3: Fix the BAT issues due to incorrect check.
Keep the readout for vtotal intact, and just overwrite for cases where
we dont want to read vtotal. (Ville)

Ankit Nautiyal (2):
  drm/i915/display: Introduce transcoder_has_vrr() helper
  drm/i915/display: Avoid use of VTOTAL.Vtotal bits
