This should > complain in W=1 compile tests on !OF config. The Marvell family of SoC which this embedded SoC borrows HW blocks from can boot using ACPI. I doubt anybody would boot this particularly SoC using ACPI, but the drivers Chris copied probably do build !OF for when ACPI is in us. Andrew

What I wanted to say - current setting should cause warnings. Therefore choose: 1. For ACPI && !OF this should be still without of_match_ptr, to allow ACPI matching by OF (PRP0001). 2. For !OF with of_match_ptr() (weird setup... how to match then?) the ac5_pinctrl_of_match should be marked as maybe unused. Best regards, Krzysztof

This pinctrl driver supports the 98DX25xx and 98DX35xx family of chips from Marvell. It is based on the Marvell SDK with additions for various (non-gpio) pin configurations based on the datasheet.
