Subject: [PATCH v4 2/3] dt-bindings: mfd: add LP87524-Q1
Add the LP87524-Q1 to the bindings along with an example. This is a variant
of the LP87565-Q1 and LP87561-Q1 chips which already have bindings.
Signed-off-by: Luca Ceresoli <luca@...aceresoli.net>

Changes in v4:
- reformat as a standalone file
Changes in v3:
- fix yaml errors
Changes in v2:
- RFC,v1 was based on the txt file, rewrite for yaml
- use uppercase consistently in model names (Lee Jones)
- replace "regulator" -> "mfd" in subject line (Lee Jones)
- replace "dt:" suffix with "dt-bindings:" prefix in subject line
