Subject: [PATCH 0/4] backlight: ktz8866: improve it and support slave

Sending this patchset to support coming devices which are using dual
ktz8866, original driver would only handle half backlight region on
these devices, registering it twice is unreasonable,  and two devices
share the same resources(pinctrl) which is required for every single
node under recent dt-bindings, so adding new support. and improve
original driver. Details in every commit log.

Pengyu Luo (4):
  dt-bindings: backlight: kinetic,ktz8866: add ktz8866 slave compatible
  backlight: ktz8866: add slave handler
  backlight: ktz8866: improve current sinks setting
  backlight: ktz8866: add definitions to make it more readable
