Subject: [PATCH 19/20] ARM: dts: stm32: Add alternate pinmux for MP13 UART7 pins
Date: Mon, 22 Apr 2024 02:19:33 +0200	[thread overview]
Message-ID: <20240422002006.243687-19-marex@denx.de> (raw)
In-Reply-To: <20240422002006.243687-1-marex@denx.de>

Add another mux option for UART7 pins, this is used on
DH electronics STM32MP13xx DHCOR DHSBC board.
