Hi Ingi,
Thanks for the update. Please find my comments below.
On 11/10/2015 03:17 AM, Ingi Kim wrote:
This patch adds device driver of Richtek RT5033 PMIC.
The driver supports a current regulated output to drive white LEDs.
I would add here also the part from leds-rt5033.txt header.

How are you distinguishing between setting brightness for iout_joint
case and for individual LEDs? Have you tested this use case?
Even if you don't have a board with two separate LEDs,
you should be able to test two LED class devices with a single

Please rebase your code on top of LED tree devel branch:
git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds.git
Those LED core changes will be applied to the for-next branch
in the beginning of the next week, and they'll allow to get rid of
work queues and brightness_set_sync ops from drivers. Please refer
to the patches that remove related code from leds-max77693.c to
find out how to adapt your driver to benefit from LED core
optimizations.
