The input select configuration for the ECSPI2_MISO functionality being assigned to the UART5_RX_DATA pin is incorrectly configured for the i.MX6UL in the imx_3.14.52_1.1.0_ga and imx_3.14.38_6ul_ga kernels.  Specifically the Daisy Chain input register address and value is not present. Attached is a patch to the issue which was verified working on a custom i.MX6UL board.
