  backlight: pwm_bl: Set scale type for brightness curves specified in the DT (2019-09-02 15:55:15 +0100)

----------------------------------------------------------------
 - Core Frameworks
   - Obtain scale type through sysfs

 - New Functionality
   - Provide Device Tree functionality; rave-sp-backlight
   - Calculate if scale type is (non-)linear; pwm_bl

 - Fix-ups
   - Simplify code; lm3630a_bl
   - Trivial rename/whitespace/typo fixes; lms283gf05
   - Remove superfluous NULL check; tosa_lcd
   - Fix power state initialisation; gpio_backlight
   - List supported file; MAINTAINERS

 - Bug Fixes
   - Kconfig - default to not building unless requested; {LED,BACKLIGHT}_CLASS_DEVICE
