The trf7970a driver uses the voltage from the power/regulator subsystem to determine what the voltage on the VIN pin is. Normally, this is the right thing to do but sometimes the board that the trf7970a is on may change the voltage. This is the case for the trf7970atb board from Texas Instruments where it boosts the VIN voltage from 3.3V to 5V (see http://www.ti.com/tool/trf7970atb). To handle this, add support for the 'vin-voltage-override' device tree property which overrides the voltage value given by the regulator subsystem. When the DT property is not present, the value from the regulator subsystem is used. The value of 'vin-voltage-override' is in uVolts. Signed-off-by: Mark A.
