This framework presents clustered colored LEDs into an array and allows the user space to adjust the brightness of the cluster using a single file write. The individual colored LEDs intensities are controlled via a single file that is an array of LEDs A design alternative to having files that have multiple values written to a single file is here: https://lore.kernel.org/patchwork/patch/1186194/* Dan Murphy (17): dt: bindings: Add multicolor class dt bindings documention leds: Add multicolor ID to the color ID list leds: multicolor: Introduce a multicolor class definition dt: bindings: lp50xx: Introduce the lp50xx family of RGB drivers leds: lp50xx: Add the LP50XX family of the RGB LED driver dt: bindings: lp55xx: Be consistent in the document with LED acronym dt: bindings: lp55xx: Update binding for Multicolor Framework ARM: dts: n900: Add reg property to the LP5523 channel node ARM: dts: imx6dl-yapp4: Add reg property to the lp5562 channel node ARM: dts: ste-href: Add reg property to the LP5521 channel nodes leds: lp55xx: Convert LED class registration to devm_* leds: lp55xx: Add multicolor framework support to lp55xx leds: lp5523: Update the lp5523 code to add multicolor brightness function leds: lp5521: Add multicolor framework multicolor brightness support leds: lp55xx: Fix checkpatch file permissions issues leds: lp5523: Fix checkpatch issues in the code dt: bindings: Update lp55xx binding to recommended LED naming .../ABI/testing/sysfs-class-led-multicolor | 42 + .../bindings/leds/leds-class-multicolor.txt | 98 +++ .../devicetree/bindings/leds/leds-lp50xx.txt | 148 ++++ .../devicetree/bindings/leds/leds-lp55xx.txt | 163 +++- Documentation/leds/index.rst | 1 + Documentation/leds/leds-class-multicolor.rst | 92 +++ arch/arm/boot/dts/imx6dl-yapp4-common.dtsi | 14 +- arch/arm/boot/dts/omap3-n900.dts | 29 +- arch/arm/boot/dts/ste-href.dtsi | 22 +- drivers/leds/Kconfig | 22 + drivers/leds/Makefile | 2 + drivers/leds/led-class-multicolor.c | 206 +++++ drivers/leds/led-core.c | 1 + drivers/leds/leds-lp50xx.c | 778 ++++++++++++++++++ drivers/leds/leds-lp5521.c | 43 +- drivers/leds/leds-lp5523.c | 62 +- drivers/leds/leds-lp5562.c | 22 +- drivers/leds/leds-lp55xx-common.c | 213 +++-- drivers/leds/leds-lp55xx-common.h | 13 +- drivers/leds/leds-lp8501.c | 23 +- include/dt-bindings/leds/common.h | 3 +- include/linux/led-class-multicolor.h | 121 +++ include/linux/platform_data/leds-lp55xx.h | 8 + 23 files changed, 1968 insertions(+), 158 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-class-led-multicolor create mode 100644 Documentation/devicetree/bindings/leds/leds-class-multicolor.txt create mode 100644 Documentation/devicetree/bindings/leds/leds-lp50xx.txt create mode 100644 Documentation/leds/leds-class-multicolor.rst create mode 100644 drivers/leds/led-class-multicolor.c create mode 100644 drivers/leds/leds-lp50xx.c create mode 100644 include/linux/led-class-multicolor.h
