I need to use uart3 for my bluetooth module, by default, I can't find /dev/ttymxc2 when system boot up, after look into 3.5.7 kernel and modify device tree structure at ~/arch/arm/boot/dts/imx6qdl-sabreauto.dtsi and ~/arch/arm/boot/dts/imx6q.dtsi, now I have /dev/ttymxc2.
But unfortunately, it can't work.
I want to know if I still miss any modificatioin to enable this UART3, please help, thanks.
PS. my platform is i.MX6 base board with SABRE for automotive infotainment cpu board, uart3 interface is on i.MX6 base board
Thanks in advanced
