Subject: [PATCH v2 00/14] drm/sun4i: Allwinner D1 Display Engine 2.0 Support

This series adds binding and driver support for Display Engine 2.0
variant found in the Allwinner D1.

So far it has only been tested with HDMI. I will be sending the HDMI
support series separately, because the hardware comes with a brand new
custom HDMI PHY, which requires some refactoring to support cleanly.

This series was tested on A33, D1 and H3.

Changes in v2:
 - New patch: I/O helper portability
 - Use Jernej's patches for mixer mode setting.
 - Use an enumeration for the ccsc value.

Jernej Skrabec (3):
  sun4i/drm: engine: Add mode_set callback
  sun4i/drm: backend: use mode_set engine callback
  sun4i/drm: sun8i: use mode_set engine callback

Samuel Holland (11):
  dt-bindings: display: Separate clock item lists by compatible
  dt-bindings: display: Add D1 display engine compatibles
  drm/sun4i: Remove obsolete references to PHYS_OFFSET
  drm/sun4i: hdmi: Use more portable I/O helpers
  drm/sun4i: Allow building the driver on RISC-V
  drm/sun4i: Allow VI layers to be primary planes
  drm/sun4i: csc: Add support for the new MMIO layout
  drm/sun4i: Add support for D1 mixers
  drm/sun4i: Add support for D1 TCON TOP
  drm/sun4i: Add support for D1 TCONs
  drm/sun4i: Add compatible for D1 display engine
