This patch reconfigures dat1 as a GPIO before going to suspend. SDIO interrupts are detected with the GPIO, the GPIO will only wake the module from suspend, SDIO irq detection will still happen through the IP block. Idea of remuxing the pins by Tony Lindgren.

Probably the reason for not merging the SDIO interrupt patches has been the lack of wake-up path for SDIO on some omaps that has also needed remuxing the SDIO DAT1 line to a GPIO making the patches complex. This patch adds the minimal SDIO IRQ support to hsmmc for omaps that do have the wake-up path. For those omaps, the DAT1 line need to have the wake-up enable bit set, and the wake-up interrupt is the same as for the MMC controller. This patch has been tested on am3730 es1.2 with mwifiex connected to MMC3 with mwifiex waking to Ethernet traffic from off-idle mode. Note that for omaps that do not have the SDIO wake-up path, this patch will not work for idle modes and further patches for remuxing DAT1 to GPIO are needed. Based on earlier patches [1][2] by David Vrabel <david.vrabel@csr.com>, Steve Sakoman <steve@sakoman.com> For now, only support SDIO interrupt if we are booted with a separate wake-irq configued via device tree. This is because omaps need the wake-irq for idle states, and some omaps need special quirks. And we don't want to add new legacy mux platform init code callbacks any longer as we are moving to DT based booting anyways. To use it, you need to specify the wake-irq using the interrupts-extended property.
