I start working on moving mxs gpio (arch/arm/mach-mxs/gpio.c) into driver/gpio, and I see the possibility to go a different approach from U300 one posted here.I've tried to figure out what relation the mail has to the U300 driver but cannot find any, more than that it's moving a driver... Please start a new mail thread.I will post mxs-gpio driver once I get it done. Then please review the code and see the difference between mxs-gpio and u300-gpio, though these hardwares have something in common.I'm pretty sure they have something in common and even more that *all* gpio drivers have something in common. I wonder if it really makes sense to move the gpio driver to drivers/gpio without creating a common mmio_gpio_chip beforehand. This can't be very hard.
Jamie Iles (cc'ed) posted some patches that extended the basic_mmio_gpio driver so that it could be used as a library by other gpio drivers. Jamie, could you re-post that series to the linux-arm-kernel list for review? Thanks, Hartley
