From: Nicolas Ferre <nicolas.ferre@microchip.com>
TDES doesn't probe because of lack of DMA channels left on this controller. As we don't need TDES HW engine, we prefer to keep DMA channels for other usage. Disable TDES for this board.
Signed-off-by: Nicolas Ferre <nicolas.ferre@microchip.com> --- Hi,
Tell me what you think about this move. I think it makes sense but tell me if application could suffer from this lack of TDES engine.
Regards, Nicolas
