These LEDs are used both as lantern and camera flash on phones based on the MSM8974 SoC, like the Nexus 5. Signed-off-by: Nícolas F. R. A. Prado Reviewed-by: Rob Herring --- Changes in v3: - Removed clamp-curr, headroom, startup-dly and safety-timer properties since they didn't impact the behavior. They're now hardcoded in the driver (patch 2) - Added valid ranges for led-max-microamp, flash-max-microamp and flash-max-timeout-us - Removed dt-bindings header file that held some constants (moved to inside the driver in patch 2) Added in v2 .../bindings/leds/leds-qcom-spmi-flash.yaml | 93 +++++++++++++++++++ 1 file changed, 93 insertions(+) create mode 100644 Documentation/devicetree/bindings/leds/leds-qcom-spmi-flash.yaml diff --git a/Documentation/devicetree/bindings/leds/leds-qcom-spmi-flash.yaml b/Documentation/devicetree/bindings/leds/leds-qcom-spmi-flash.yaml new file mode 100644 index 000000000000..da674d73c033 --- /dev/null +++ b/Documentation/devicetree/bindings/leds/leds-qcom-spmi-flash.yaml @@ -0,0 +1,93 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/leds/leds-qcom-spmi-flash.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm SPMI Flash LEDs + +maintainers: + - Nícolas F.
