Subject: [PATCH v2] mfd: dt-bindings: Convert TPS65910 to DT schema
Convert the TI TPS65910 documentation to DT schema format.
Fix incorrect I2C address in example: should be 0x2d.
TPS65910 datasheet: https://www.ti.com/lit/gpn/tps65910
Signed-off-by: Shree Ramamoorthy <s-ramamoorthy@...com>
---
v1 -> v2:
- Remove references to old docs
- Change ti,vmbch-threshold & ti,vmbch2-threshold to uint32
- Remove constraints from description text
- Change all unevaluatedProperties instances to false
- additionalProperties set to false & moved to 'regulators' property
- Shorten regex to ^vcc(io|[1-7])-supply$
- Add blank line between vcc(io|[1-7])-supply description paragraphs
- Change DTS example indentation to use 4 spaces
- Drop unused labels (vrtc_reg node) from DTS example
