[PATCH v5 0/4] Add DT support for netxbig LEDs

[Simon Guinot]

Hello,

This patch series adds DT support for the LEDs found on the Kirkwood-based
LaCie boards 2Big and 5Big Network v2.

Changes for v2:
- Check timer mode value retrieved from DT.
- In netxbig_leds_get_of_pdata, don't use unsigned long variables to get
  timer delay values from DT with function of_property_read_u32_index.
  Instead, use a temporary u32 variable. This allows to silence a static
  checker warning.
- Make timer property optional in the binding documentation. It is now
  aligned with the driver code.

Changes for v3:
- Fix pointer usage with the temporary u32 variable while calling
  of_property_read_u32_index.

Changes for v4:
- In DT binding document netxbig-gpio-ext.txt, detail byte order for
  registers and latch mechanism for "enable-gpio".
- In leds-netxbig.c, add some error messages.
- In leds-netxbig.c, fix some "sizeof" style issues.
- In leds-netxbig.c, in netxbig_leds_get_of_pdata(), move the
  of_property_read_string() calls after the error-prone checks.
- Add some Acked-by.

Changes for v5:
- Rename DT property "bright-max" into the more common "max-brightness".
- Make use of the "max-brightness" DT property. Instead of counting the
  data pins of the GPIO extension bus, use "max-brightness" to get the
  maximum brightness level.
- Add a patch to convert the leds-netxbig driver to the devm_ functions.

Thanks,

Simon
