Subject: [RFC PATCH] Add pin control driver for Wondermedia SoCS
Newsgroups: gmane.linux.kernel
Date: Friday 15th February 2013 02:48:53 UTC (over 3 years ago)
Before I get all carried away and start filling in all the data for
this driver, I was hoping someone (or a few people) could review the
basic design in case it requires changes to the data structures.

This driver is based on pinctrl-bcm2835.c as it seems to be similar in
design. The pin controller on Wondermedia SoC's only allows each pin to
either be a GPIO or to be its 'alternate' function. Functions cannot be
remapped to any other pin.

I have seperated out the data from the code as there are several SoC's
to support and each has it's own variation of registers / pin layout.
I borrowed this part of the design from the Tegra pinctrl driver.

Regards
Tony Prisk
