From 92b33c010e612cccc069d25a354dabc1380e5cb9 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Mon, 25 Nov 2019 13:22:55 +0100 Subject: ARM: dts: ux500: Add pin configs for UART1 CTS/RTS pins UART1 can optionally be used with additional CTS/RTS pins. The pinctrl driver has an extra "u1ctsrts_a_1" pin group for them. Add a new pin configuration to configure them correctly if needed.
