Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] The schema does not enforce `flash-max-microamp`, `flash-max-timeout-us`, and `led-max-microamp` as required properties for the LED child node.

dt-bindings: leds: Document TI LM3643 dual LED flash driver

This commit documents the devicetree bindings for the Texas Instruments LM3643
dual LED flash driver, which uses a synchronous boost converter to power up to
two current sources up to 1.5A.

[Severity: High]
Should flash-max-microamp, flash-max-timeout-us, and led-max-microamp be
included here as required properties for the LED child node?

Without these properties enforced by the schema, a device tree could omit them
and still pass validation. If omitted, will driver fallback to the controller's
absolute maximums (1.5A and 400ms) risk physically damaging connected LEDs that
have lower electrical limits?
