Subject: [PATCH] arm64: dts: st: Move Bluetooth to USART2 on STM32MP23xx DHCOS SoM
Date: Mon, 26 Oct 2026 13:51:38 +0100 [thread overview]
Message-ID: <20261026125201.76716-1-marex@nabladev.com> (raw)
The Bluetooth chip is connected to USART2 on STM32MP23xx DHCOS SoM,
adjust the DT to match the schematic.
Fixes: 6642d6a47901 ("arm64: dts: st: Add support for DH electronics STM32MP23xx/STM32MP25xx DHCOS SoM and Breakout Board and DHSBC")
