-Subject: [PATCH] overlays: Add MAX31856 support to maxtherm overlay
-
-Extend the maxtherm overlay with support for the MAX31856.
-The driver reads the thermocouple type from a property, which is much
-more civilised.
-
-See: https://github.com/raspberrypi/linux/issues/3915

-+Info:   Configure a MAX6675, MAX31855 or MAX31856 thermocouple as an IIO device.
-         For devices on spi1 or spi2, the interfaces should be enabled
-         with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
-         The overlay expects to disable the relevant spidev node, so also using
-         e.g. cs0_spidev=off is unnecessary.
--        Note:   with the 5.7 kernel (and later) there will also be
--                overlays for MAX31855E, MAX31855J, MAX31855K,
--                MAX31885N, MAX31855R, MAX31855S and MAX31855T.
