+===================================================================================================
+ The dts file contains pinctrl to set the pull-up and pull-down features using the at91 pinctrl
+ driver. Because pins seemed to be assigned random values if not set, it is probably good
+ to set any pin used by mts-io here, and it wouldn't be a bad idea to set unused pins as well,
+ since they can be both pull-up and pull-down at the same time.
+ For future hardware revisions, it should be possible to overwrite the pinctrl with an overlay
+ prior to loading the mts-io driver.
+
+ To use the pinctrl, one must call platform_device_register() in the driver.
