[v6,0/4] Qualcomm Light Pulse Generator

Message

This series introduces a generic pattern interface in the LED class and
a driver for the Qualcomm Light Pulse Generator.

It seems like it's been almost 3 years since I posted v3, which was hung
up on the lack of conclusion on the hw_pattern and multicolor support.
Now that those are concluded I hope we can make some progress on the LPG
support again.

The dts patches are included in the series as "examples", ultimately my
expectation is that the dt binding and driver patches are picked up
through the leds tree, while Andy or myself take the dts patches.

Bjorn Andersson (4):
  dt-bindings: leds: Add Qualcomm Light Pulse Generator binding
  leds: Add driver for Qualcomm LPG
  arm64: dts: qcom: pm(i)8994: Add mpp and lpg blocks
  arm64: dts: qcom: Add user LEDs on db820c
