Signed-off-by: Thierry Reding <[email protected]>
---
Changes in v4:
- add reset and reset-names properties
Changes in v3:
- add #address-cells and #size-cells properties for DSI bus
- update for revised MIPI calibration bindings
- add low-power clocks
Changes in v2:
- use a comment to describe which pads need calibration
