[PATCH 0/1] dt-bindings: mfd: add ti,lm8502 LED + haptic controller

[Herman van Hazendonk]

Add a YAML binding for the TI LM8502, an I2C combo LED + haptic
controller used in the HP TouchPad (MSM8x60 / APQ8060) tablet.

The LM8502 exposes ten constant-current LED outputs (D1..D10) and an
internal H-bridge for driving a vibrator motor. Pin D10 is shared
between the tenth LED channel and the haptic output; the haptic child
driver mux's D10 to the H-bridge path at each FF_RUMBLE event.

The device is modelled as an MFD with two child sub-nodes:

  ti,lm8502-leds   - LED-class outputs D1..D10 (per-LED reg +
                     led-max-microamp properties)
  ti,lm8502-haptic - EV_FF / FF_RUMBLE input device for the
                     internal H-bridge, with optional
                     ti,invert-direction property

The MFD core driver was already sent separately:
  "[PATCH v2 0/1] mfd: lm8502: add core MFD driver for TI LM8502"
  Message-ID: <20260603040026.398009-1-github.com@xxxxxxxxxx>

Child drivers (leds-lm8502, input-lm8502-haptic) will follow as
separate series once the binding and core are accepted.
