Bug Description
[Impact]
On Advantech UNO-420 development platform, we need a generic way to set the pin mode.
Upstream would like us to leverage ACPI override method to change the modes, but in Ubuntu core, we can't generate a new initramfs and boot up with the generated initramfs.
[Fix]
Add a module parameter to assign pin modes while loading ad5593r driver.
[Test]
Verified on Advantech UNO-420 platform.
[Regression Potential]
It checks the length of the passed parameter, and checks every bytes
in it to make sure it's a valid argument. There should be no index out
of range issue, and no wrong pin mode would be set.
