Message

Hi,

This series adds support for Microchip OTP controller available on
SAMA7G5. The driver gives access to a non-volatile memory which
keeps (at the moment) information like booting media and temperature
calibration data used for thermal measurements.

Thank you,
Claudiu Beznea

Changes in v2:
- updated the bindings (patch 1/2) as follows:
	- included the device name in files names and updated binding
	  content accordingly
	- updated the description
	- removed address-cells, size-cells
	- removed clock include
	- use GPL-2.0 OR BSD-2-Clause license
	- removed OTP_PKT_SAMA7G5_TEMP_CALIB_LEN and keep hardcoded
	  value in examples
	  
- updated MAINTAINERS file with new naming of bindings
