WM8904 interface enable method now returns the previous interrupt state.  Correct ordering of some WM8904: Need to provide MCLK before initializing the WM8904, not after

WM8904:  Ad the MCLK frequency to the interface definition.  The WM8904 driver needs to know this frequency in order to configure the FLL to generate the correct bitrate

dd support for a USB keyboard as the NxConsole and text widget input.  Not fully functional as of this initial check-in.  Basic functionality is there, but there are conditions were the keyboard gets lost.

SAMA5 HSMCI: e-enable TX DMA and verify that DMA writes to the SD card are functional.  They are so now TX DMA is re-enabled in the driver.  This might affect the SAMA5D3 platforms where the TX DMA problem was found.  The SAMA4D3 and 4 use the same HSMCI driver.  Much has change since then and it is not surprising that DMA is now functional.  However, the has not be re-verified on the SAMA5D3 which has a different DMA controller.

The SAMA5D4-EK NSH and NxWM configurations now have the auto-mounter configured to automatically mount the FAT file system on HSMCI0 at /mnt/sdcard

SAMA5D4-EK: Add logic to disable the faulty PMIC.  This must be done with JP23 open.  It is perfomed only from the DRAMBOOT loader

Change naming from cp_XYZ_cache() to arch_XYP_cache() so that all cache operations will pick up L2 support if it is enabled

NxWM: Beginning integration of NxPlayer into Nxwm::MediaPlayer. Gets handle, sets device, and releases handle.  Lots more to be done

SAMA5D4-EK NSH:  Enable the command line media player in the NSH configuration as well (still does not work, however).
