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
