[PATCH v5 0/5] leds: trigger: Add pattern initialization from Device Tree

[Krzysztof Kozlowski]

Hi,

Changes since v4:
1. Move helper to get default pattern from led-class.c to led-core.c and
   rename it (build issue pointed by kbuild robot).

Changes since v3:
1. Add missing EXPORT_SYMBOL_GPL.
2. Put pattern trigger format into common file - shared between
   dt-bindings and sysfs.
3. Use array of integers as led-pattern property (since it is bigger change
   I did not add Pavel's ack to patch 2/5).
4. Mention ms units for led-pattern bindings.

Changes since v2:
1. Drop Jacek's patches and my "led: triggers: Initialize
   LED_INIT_DEFAULT_TRIGGER if trigger is brought after class".
2. Follow Rob's advices about bindings - use "led-pattern" property
   and generalize usage of it into to three triggers.
3. New patches (2/5, 4/5 and 5/5).

Changes since v1:
1. Rebase on Jacek's patches.
2. Add patch 3/5 for fixup of Jacek's solution.
3. Drop first two patches from the series (applied).
4. Patch 5/5: Use LED_INIT_DEFAULT_TRIGGER (suggested by Jacek Anaszewski).
5. Patch 5/5: Return-on-error and log warning (suggested by Pavel Machek).


Best regards,
Krzysztof
