Subject: [PATCH 0/2] leds: pwm: Add default-brightness property

led-pwm driver supports default-state DT property and if that state is on then
the driver during initialization turns on the LED setting maximum brightness.
Sometimes it's desirable to use lower initial brightness.
This patch series adds support for DT property default-brightness.

Patch series is prepared for linux-next

Things to discuss:
If such a property is acceptable it could be moved to leds/common.yaml due to
several drivers support multiple brightness levels and could support the property
too.
