drivers: hwinfo: add driver support for Atmel SAM0 device ID Add driver support for Atmel SAM0 device ID, which is 16-bytes long. The device ID can simply be read from memory at a known location, but the location is only described in the data sheet, not in ASF. For SAMD2x it's 0x0080A00C, 0x0080A040, 0x0080A044 & 0x0080A048. For SAMD5x it's 0x008061FC, 0x00806010, 0x00806014 & 0x00806018. This adds a new property to the device tree to define the device ID registers for this SoC family.

title: Atmel Device ID (Serial Number) binding
version: 0.1
description: >
Binding for locating the Device ID (serial number) on Atmel SAM0 devices.
dts/bindings: Move common properties into a base.yaml Move common properties like 'compatible', 'reg', 'reg-names', 'interrupts', 'interrupt-names', and 'label' into one common base.yaml that all the other yaml's can inherit from. This removes both duplication and inconsistent definition. The device specific yamls just need to say if a property is 'required' or not. NOTE: due to some generation conflicts we did not covert 'soc-nv-flash.yaml' to use base.yaml. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
