I am working on a customised i.MX6 Dual board. The board supports 4 UART's but all are used. So, I need to use software UART. I am having 2 GPIO's that I need to configure as UART's Rx and Tx.

OS - Linux

Kernel - 3.10

BSP - Yocto


Can anybody suggest me how to configure GPIO's as a UART or refer some code example ?
