Subject: [PATCH v3 0/4] drm/dsi/tegra: continuous clock support

This small series adds a flag that allows to specify that a DSI device supports
non-continuous clock mode, and uses it in the Tegra DSI driver to only enable
this mode on panels that support it. Until now, the Tegra DSI driver
unconditionally enabled non-continuous mode, which prevented continous-mode-only
panels from working with it.

This allows us to enable the panel embedded in NVIDIA SHIELD and which only
supports continuous mode.

Changes since v2:
- Changed the flag to enable non-continuous behavior instead of the contrary,
  to match the DSI spec more closely and highlight the fact continuous behavior
  is the default

Changes since v1:
- Removed unneeded regulator-always-on property for vdd_lcd regulator

Alexandre Courbot (4):
  drm/dsi: Flag for non-continuous clock behavior
  drm/panel: Set non-continuous clock flag on supporting panels
  drm/tegra: dsi - Handle non-continuous clock flag
  ARM: tegra: roth: add display DT node
