Subject: [PATCH v5 1/3] dt-bindings: mfd: lp87565: convert to yaml
Also apply a few smaller improvements:
- document that the only possible I2C slave address is 0x60 as per the
datasheet and fix the second example accordingly
- The definition of "xxx-in-supply" was generic, thus define in detail the
possible cases for each chip variant
- remove "MFD driver" from the title as it is implementation specific
- replace "PMIC" with "buck converter" in title as it is more informative
Signed-off-by: Luca Ceresoli <luca@...aceresoli.net>
---
Changes in v5:
- describe the "regulators" node too (Rob)
- add 'additionalProperties: false' (Rob)
- simplify supply description
- update commit message
Changes in v4:
- split in two different bindings (Rob)
- remove "MFD driver" from title as it is implementation specific; also
replace "PMIC" with "buck converter" which is more informative
Changes in v3:
- fix yaml errors
Changes in v2:
- this patch replaces patch "regulator: lp87565: dt: remove duplicated
section" in RFC,v1 (Rob Herring)
- use capital letters consistently (Lee Jones)
- replace "regulator" -> "mfd" in subject line (Lee Jones)
- replace "dt:" suffix with "dt-bindings:" prefix in subject line
