Subject: [PATCH v2 0/9] Support TI LMU devices
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.
