Krzysztof Kozlowski 8a1e6bb3f7 dt-bindings: update Krzysztof Kozlowski's email
Krzysztof Kozlowski's @canonical.com email stopped working, so switch to
generic @kernel.org account for all Devicetree bindings.

description: |
This is a part of device tree bindings for Maxim MAX77693 MicroUSB Integrated
Circuit (MUIC).
There are two LED outputs available - FLED1 and FLED2. Each of them can
control a separate LED or they can be connected together to double the
maximum current for a single connected LED. One LED is represented by one
child node.
See also Documentation/devicetree/bindings/mfd/maxim,max77693.yaml for
additional information and example.

maxim,boost-mode:
description:
In boost mode the device can produce up to 1.2A of total current on both
outputs. The maximum current on each output is reduced to 625mA then. If
not enabled explicitly, boost setting defaults to LEDS_BOOST_FIXED in
case both current sources are used.
See LEDS_BOOST_* in include/dt-bindings/leds/common.h.
