Subject: [PATCH] dtoverlays: Add the iio_hwmon driver to correct ADC
|
|
issues
|
|
|
|
The Linux kernel maintainers removed the hwmon driver for the
|
|
ads1015 used on this board. They deprecated it in favor of using
|
|
the IIO version of the driver with the iio_hwmon bridge. This
|
|
patch updates the DRAWS dtoverlay to support that usage.
