   4 Subject: [PATCH 095/117] dt-bindings: display: sun6i-dsi: Add the A100 variant
   5
   6 The "40nm" MIPI DSI controller found in the A100 and D1 SoCs has the
   7 same register layout as previous SoC integrations. However, its module
   8 clock now comes from the TCON, which means it no longer runs at a fixed
   9 rate, so this needs to be distinguished in the driver.
  10
  11 The controller also now uses pins on Port D instead of dedicated pins,
  12 so it drops the separate power domain.
  13
  14 Commit-notes:
  15 Removal of the vcc-dsi-supply is maybe a bit questionable. Since there
  16 is no "VCC-DSI" pin anymore, it's not obvious which pin actually does
  17 power the DSI controller/PHY. Possibly power comes from VCC-PD or VCC-IO
  18 or VCC-LVDS. So far, all boards have all of these as always-on supplies,
  19 so it is hard to test.
