iio: dac: mcp4725: Use of_property_present() for non-boolean properties

[PATCH] iio: dac: mcp4725: Use of_property_present() for non-boolean properties

Posted by Rob Herring (Arm) 2 weeks, 5 days ago

The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.

Applied to the testing branch of iio.git. I'll rebase that on 6.13-rc1
