This patchset is a driver for the TI tlc59116 16 Channel i2c LED
driver and tlc59108 8 Channel i2c LED driver. This driver is used on
the Belkin WRT1900AC access point and the C code is derived from code
Belkin contributed to OpenWRT.  However it has been extensively
re-written, and a device tree binding added to replace platform data.

Since v5:
      Hard code number of LEDs, rather than #define
      Moved common fields from led into priv
      Moved reg_ledout into priv, removed helper functions
      Cache brightness to avoid race conditions
      tlc591xx_led_set -> tlc591xx_set_brightness
      Be paranoid with of_match_device() and client->dev.of_node

Since v4:
      Fix Oops on module unload reported by Vignesh R

Since v3:
      Generalized and added support for tlc59108
      brightness == 0 and brightness == LED_FULL disable PWM and used
        fixed OFF/ON mode

Since v2:
      Remove incorrect /* Mode register ? */ comment
      Parenthesis around the macro arguments
      Converted many signed variables into unsigned
      Saved an initialization


Since v1:
      s/uint8_t/u8/g
      Remove empty line
      Removed #gpio-cells
      Added select REGMAP_I2C
      Sorted #includes into alphabetic order
      Added missing MODULE_DEVICE_TABLE(of, ...)
      Check return value of regmap_write()
      Simplified tlc59116_set_mode()
