[PATCH v7 0/2] leds: Add IS32FL3207 controller support

[Ahmad Byagowi <ahmadexp@gmail.com>]

Add a binding and LED-class driver for the Lumissil IS32FL3207
18-channel constant-current LED controller. The driver supports individual
and multicolor LEDs, per-output current limits, an optional supply, and an
optional SDB GPIO.

This is the LED prerequisite split out of the Time Card series. The
dependent ptp_ocp board profiles will be resent to net-next after the LED
and I2C prerequisites land.

---

Changes since v6:
  - Restore the led-max-microamp schema minimum to 1 uA because the
    smallest representable nonzero current depends on the RISET value.
  - Document the RISET-dependent nonzero current-scaling requirement for
    individual and multicolor outputs.
  - Keep the driver patch unchanged.

Krzysztof's Reviewed-by from v3 is not carried because the binding changed
materially after that review. It now supports groups beginning at outputs
16 and 17 and documents the RISET/current-limit relationship.

Validation:
  - dt-doc-validate
  - dt-check-style --mode strict
  - yamllint
  - git diff --check
  - strict checkpatch
  - x86-64 Clang syntax check

v6: https://lore.kernel.org/r/cover.1787247467.git.ahmadexp@gmail.com/
