[PATCH v2 0/6] leds: lm3692x: Allow to set ovp and brigthness mode

[Guido GÃnther]

Overvoltage protection and brightness mode are currently hardcoded
as 29V and disabled in the driver. Make these configurable via DT.

Besides addressing review comments v2 also allows to limit the maximum led
current.

Changes from v1
- As per review comments by Dan Murphy
  https://lore.kernel.org/linux-leds/3d66b07d-b4c5-43e6-4378-d63cc84b8d43@xxxxxx/
  - Split commits per propoerty
  - Add new properties to DT example too
  - Drop dev_dbg() statements
  - ovp: fix 21V value parsing
  - ovp: Set correct default value if DT parsing fails
- As per review comments by Pavel Machek
  https://lore.kernel.org/linux-leds/20191221191515.GF32732@amd/
  - Fix defaults (which is 29V)
  - Use uV as Unit for ovp property
- Change property name to 'ti,ovp-microvolt' to make it shorter
- Honor led-max-microamp to not exceed the maximum led current
