This patch adds the device tree bindings for ktd2692 flash LEDs. Add optional properties 'flash-timeout-us' to control flash timeout and 'vin-supply' for flash-led regulator Signed-off-by: Ingi Kim <ingi2.kim@samsung.com> --- .../devicetree/bindings/leds/leds-ktd2692.txt | 37 ++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 Documentation/devicetree/bindings/leds/leds-ktd2692.txt
