From: Hari Nagalla <hnagalla@xxxxxx> The wilink module is a combo wireless connectivity sdio card based on Texas Instrument's wl18xx solution. It is a 4-wire, 1.8V, embedded sdio wlan device with an external irq line and is power-controlled by a gpio-based fixed regulator. Add pinmux configuration and IODelay values for MMC4. On dra7-evm, MMC4 is used for connecting to wilink module.
