Pad config registers exist in APB_MISC_GP space, and control slew rate, drive strengh, schmidt, high-speed, and low-power modes for all of the pingroups in Tegra30. This builds off of the pinmux way of constructing init tables to configure select pads (SDIOCFG, for instance) during pinmux_init(). Currently, no padcfg entries exist. SDIO3CFG will be added when the MMC driver is added as per the TRM to work with the SD-card slot on Dalmore E1611.
