Hi, This adds backlight support for TI LMU devices. It was tested with an lm3532 on Motorola Droid 4, which uses one channel for display backlight and one channel for keyboard backlight. Changes since PATCHv3: * Complete overhaul to satisfy Rob's remarks regarding to the binding * Implement LED subsystem support for keyboard backlights * Add lots of cleanup patches for the TI LMU MFD driver Changes since PATCHv2: * Drop all binding parts, that were NAK'd by Rob. Changes since PATCHv1: * split dt-binding documentation in its own patch * move include/linux/mfd/ti-lmu-backlight.h to drivers/video/backlight/ti-lmu-backlight-data.h * replace LMU_BL_REG() with a normal struct * add "const" keyword to lots of internal structures * improve error handling * use atomic pwm api -- Sebastian Sebastian Reichel (10): mfd: ti-lmu: constify mfd_cell tables mfd: ti-lmu: switch to gpiod mfd: ti-lmu: use managed resource for everything mfd: ti-lmu: drop of_compatible for backlight driver mfd: ti-lmu: use of_device_get_match_data() helper mfd: ti-lmu: add PWM support mfd: ti-lmu: register one backlight device per channel backlight: add TI LMU backlight driver dt-bindings: mfd: ti-lmu: update for backlight ARM: dts: omap4-droid4: update backlight led-controller Documentation/devicetree/bindings/mfd/ti-lmu.txt | 119 ++-- arch/arm/boot/dts/omap4-droid4-xt894.dts | 20 +- drivers/mfd/ti-lmu.c | 170 +++--- drivers/video/backlight/Kconfig | 7 + drivers/video/backlight/Makefile | 3 + drivers/video/backlight/ti-lmu-backlight-core.c | 666 +++++++++++++++++++++++ drivers/video/backlight/ti-lmu-backlight-data.c | 304 +++++++++++ drivers/video/backlight/ti-lmu-backlight-data.h | 95 ++++ include/linux/mfd/ti-lmu.h | 10 +- 9 files changed, 1257 insertions(+), 137 deletions(-) create mode 100644 drivers/video/backlight/ti-lmu-backlight-core.c create mode 100644 drivers/video/backlight/ti-lmu-backlight-data.c create mode 100644 drivers/video/backlight/ti-lmu-backlight-data.h -- 2.16.2 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
