[PATCH v3 0/6] drm/msm/dsi regulator improvements

[Douglas Anderson]

The main goal of this series is to make a small dent in cleaning up
the way we deal with regulator loads for DSI drivers.

As of v3 of this series, the regulator API improvements needed for the
later patches in the series are merged into mainline. Thus this series
only contains the DSI changes now.

I'd expect:
* The first two patches are bugfixes found while converting the DSI
  driver over. Those could land any time.
* The third patch ("drm/msm/dsi: Don't set a load before disabling a
  regulator") is a patch a sent the other day verbatim, included in
  this series because it's highly related. It could land any
  time.
* The next two patches use the new APIs. Since those APIs are now in
  mainline those could also land any time.
* The last patch is just cleanup I noticed as I was touching the
  function. It's not really related to regulators but it applies atop
  these. In theory it could be rebased to land separately.

Changes in v3:
- ("Improve dsi_phy_driver_probe() probe error handling") new for v3.
- Do all the PHYs too.
- Fix typo in commit message.
- Get rid of error print after devm_regulator_bulk_get_const().
- Just directly call the bulk commands; get rid of the wrapper.
- Update commit message to point at the git hash of the regulator change.

Changes in v2:
- ("Fix number of regulators for SDM660") new for v2.
- ("Fix number of regulators for msm8996_dsi_cfg") new for v2.
- ("Take advantage of devm_regulator_bulk_get_const") new for v2.
- ("Use the new regulator bulk feature to specify the load") new for v2.
