Module Name:    src
Committed By:   thorpej

Modified Files:
        src/sys/dev/spi [thorpej-i2c-spi-conf]: mcp3k.c

Log Message:
If we were directly configured using the platform device tree, consult
the device tree for our reference voltage and make the vref sysctl read-only
in that case.  Implement this for the Device Tree bindings for this device
(the "vref-supply" property points to the regulator providing the reference
voltage).
