Hello! I was debugging WiFi performance problems that I started to notice on Acer A500 and found couple problems. One discovered problem lays in a wrong SDIO PINCTRL configuration of A500 device-tree, others are found in MMC core and brcmfmac driver. This series fixes the PINCTRL configuration and improves MMC clock setup of Acer A500 and Nexus 7 WiFi. Big thanks to Wright Feng of Cypress who indirectly helped me to notice the PINCTRL bug by showing MMC IOS info of the BCM4329 setup that Wright uses, it lead me to re-check to the PINCTRL configuration!
