Subject: [PATCH 0/3] mfd: da9062: Make the use of IRQ optional

For the core functionality of the MFD DA9061/62 IRQ isn't needed. This
series removes the requirement for an IRQ. This is done by modifing the
MFD driver and regulator driver to setup the device without IRQ. This
makes the DA9061/62 chip useable for designs which haven't connected
the IRQ pin.

I tested it with a DHCOM i.MX6ULL, which is powered by a DA9061.

In this series, the DT binding file is also adapted.

  mfd: da9062: Remove IRQ requirement
  regulator: da9062: Make the use of IRQ optional
