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