Hi,

This series adds support for the Raspberry Pis OTP registers. The
Raspberry Pi has one or more OTP regions. These registers are accessible
through the firmware. Add a driver for it and add the corresponding
devicetree scheme.

I also added the devicetree nodes for the Raspberry Pi as I tested the
series on it.
