Subject: [PATCH 1/3] arm64: dts: amlogic: t7: Add uart_c pinctrl pins group
Date: Wed, 15 Apr 2026 13:16:13 +0200 [thread overview]
Message-ID: <20260415-add-bluetooth-t7-vim4-v1-1-0ba0746cc1d6@aliel.fr> (raw)
In-Reply-To: <20260415-add-bluetooth-t7-vim4-v1-0-0ba0746cc1d6@aliel.fr>
Add the pin multiplexing configuration for UART C (TX, RX, CTS, RTS)
in the T7 SoC pinctrl node, required to route the UART C signals
through the correct pads before enabling the controller.
