[PATCH v6 0/2] Add RT5033 Flash LED driver

[Ingi Kim <ingi2.kim@samsung.com>]

This is a sixth version of the patch set to support RT5033 Flash Led.
It is based on RFC [1] from Jacek's patch set.

Changes since v6:
 - Make functions to convert from LED config data to register value
 - Add variables to save LED config data in rt5033_led struct
 - Rename some functions suitably
 - Change to set register of flash brightness / timeout when it was changed.

Changes since v5:
 - Rebase on Jacek's devel branch
   git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds.git
 - Remove work queue from driver.
 - Change brightness_set_sync ops to brightness_set_blocking ops.
 - Remove "iout_torch_max" and "iout_flash_max" values in rt5033_led struct.
 - Add missed case for distinguishing between setting brightness.
   for iout_joint case and for individual LEDs.
 - Add missed mutex_lock.
 - Remove guard to check dev->of_node.
 - Change type of value to const __be32 to get return value of of_find_property.

Changes since v4:
 - Use of_node_put() when DT parse miss
 - Move struct(rt5033_led) from include/linux/mfd/rt5033.h
   to local driver/leds/leds-rt5033.c
 - Remove MODULE_DEVICE_TABLE
 - Add interface to handle two LEDs.

Changes since v3:
 - Use mutex and work queue
 - Split brightness set func (sync / async)
 - Add flash API (flash_brightness_set)
 - Move struct(rt5033_led_config_data) to local area
 - Code clean

Changes since v2:
 - Split MFC code from rt5033 flash led patch
 - Fix typo error
 - Change naming of mfd register back again
 - Fix compile error

Original cover letter:
 This patch supports flash led of RT5033 PMIC.
