Subject: [PATCH 4/5] ARM: dts: ux500: Add pin configs for UART1 CTS/RTS pins
Date: Mon, 25 Nov 2019 13:22:55 +0100	[thread overview]
Message-ID: <20191125122256.53482-4-stephan@gerhold.net> (raw)
In-Reply-To: <20191125122256.53482-1-stephan@gerhold.net>

UART1 an be optionally 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.
