You probably want to use the OMAP5_CORE_IOPAD and OMAP5_WKUP_IOPAD macros for new boards as then you can easily check them against the TRM based on the physical offset of the register.

Add support for CompuLab CM-T54 CoM and SBC-T54 board:

    http://compulab.co.il/products/computer-on-modules/cm-t54/
    http://compulab.co.il/products/sbcs/sbc-t54/

Changes from V1:

* Used OMAP5_CORE_IOPAD macros for pimnux settings
* Added CD and WP support for SD/MMC card on SB-T54
* Platform quirk for deasserting PDN and RST GPIOs of WiFi chip replaced by appropriate regulators in DT.
