hwmon: (jc42) Add support for Microchip MCP9808 temperature sensor
MCP9808 is not officially compliant to JC-42, similar to MCP9804, but its registers are compatible to JC-42. Signed-off-by: Alison Schofield <amsfield22@gmail.com> Cc: Daniel Baluta <daniel.baluta@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
