TI Lighting Management Unit drivers support lighting devices below. Enable pin Backlight HW fault monitoring LEDs Regulators ---------- --------- ------------------- ---- ------------ LM3532 o o x x x LM3631 o o x x 5 regulators LM3632 o o x x 3 regulators LM3633 o o o o x LM3695 o o x x x LM3697 o o o x x This patch-set consists of several parts below. DT bindings : Binding information for each module LMU MFD : Device registration and HW enable pin control LMU fault monitor : HW fault monitoring for open and short circuit LMU backlight : Consolidated LMU backlight driver LM3633 LED : LED subsystem and dimming pattern generation supported LM363X regulator : LM3631 and LM3632 regulator driver for the display bias Updates from v1 --------------- * DT bindings mfd : Describe complete DT properties. backlight : Move backlight properties into leds/backlight/. Use common LED properties like 'led-sources' and 'label'. hwmon : LMU fault monitoring driver is not HWMON any more. So related properties are moved into 'ti-lmu' binding. leds : Use LED common properties like 'led-sources' and 'label'. * MFD Remove LMU helpers for I2C register access. Each driver uses regmap helpers instead. * LMU fault monitoring driver In v1, it was HWMON driver but HWMON subsystem maintainer suggested moving it into MFD because it has no sensor data like temperature or voltage. Device attributes were replaced with debugfs files because monitoring should be processed for debug purpose only. * Backlight Six separate driver code was consolidated. Driver control code is implemented in 'ti-lmu-backlight-core.c'. Device specific data is defined in 'ti-lmu-backlight-data.c'. 194 lines are saved in v2. The text segment is decreased by removing duplicate instructions. Lines of code: v1: 1420 (8 files) v2: 1226 (3 files) Size: v1: text data bss filename 12202 720 40 drivers/video/backlight/built-in.o v2: text data bss filename 6883 712 41 drivers/video/backlight/built-in.o * LED Use single device attribute for LED dimming operation. Max brightness is determined by DT property, 'led-max-microamp'. Remove brightness workqueue. * Regulator Use 'of_match' in regulator_desc instead of calling of_regulator_match. Remove unnecessary OF device ID because MFD core registers a platform device based on the compatible string.
