Sat Jan 8 10:07:52 PST 2022
Convert Qualcomm HDMI binding into HDMI TX and PHY yaml bindings.
Other changes:
- fixed reg-names numbering to match 0..3 instead 0,1,3,4
- phy part moved into phy/ directory
Signed-off-by: David Heidelberg <david at ixit.cz>
---
v2:
- move phy into phy/
- added maxItems for gpios
- simplified pinctrl-names
- dropped some inconsistent quotes
