Mika,
I am also trying to add ACPI enablement to my pinctrl driver (not yet submitted), but I'm new to ACPI and pin control drivers, so I have a lot of catching up to do.
In reviewing this patchset, it appears to me that pinctrl-cherryview.c is a normal pinctrl driver that has an acpi_match_table entry, and nothing more.
Assuming that this driver is booting on an ACPI system, what is the mechanism that calls into the driver to configure the pins? Is there a definition for pin control in ASL that provides similar functionality as the pinctrl nodes in a device tree?
