This patch series implements support for the Si-En SN3218
18 Channel LED Driver connected through I2C. The SN3218
doesn't support reading so the LED states are cached in a
regmap.

The driver has been tested on a Raspberry Pi B.

Changes since V1:
  * add shutdown handler
  * use defines for modes
  * remove empty line at the end of binding doc
  * make sn3218_led_init static
  * skip setting default max brightness
  * fix fail sn3218_init

Changes since RFC:
  * using regmap instead of direct I2C
  * add new function to init single LED
  * add module name to Kconfig help
  * replace of_get_property() with of_property_read_string()
  * remove lock, leds_state and name from priv structure
  * drop sn3218 LED name prefix
  * don't use led_info and led_platform_data
  * abort probing if no SN3218 is connected or DT invalid
  * fix some style and text issues
  * fix license
  * move i2c_device_id and of_device_id at the end of file
  * use devm_* calls
  * use device function as node name in DT binding

  of: Add vendor prefix for Si-En Technology
  DT: add binding for SN3218 LED driver
  leds: add SN3218 LED driver
