Subject: [PATCH] ARM: dts: imx: imx6q uart2 pin mux correction
Date: Tue, 10 Mar 2015 09:45:42 -0400	[thread overview]
Message-ID: <CAPvN=VTSMxtjs6QQ=VFPCDgJ3LJ2xfC+Ryh-rXU4-xnqk+i67w@mail.gmail.com> (raw)

This patch contains a correction to the file imx6q-pinfunc.h for the
definition of the UART2 GPIO pin mux setting.

Issue found when testing UART2 configured as the console in Linux
GPIO_7 is a transmit pin not a transmit and receive pin
GPIO_8 is a receive pin not a transmit and receive pin

Verified the correction with Freescale in posting to the Freescale
forum https://community.freescale.com/thread/343349

commit c383bbb4d17037435305858f488db7ae17dc1c85
