Subject: [PATCH v1 1/3] dt-bindings: serial: snps-dw-apb-uart: Add one more reset signal for StarFive JH7110 SoC
Date: Fri, 17 May 2024 14:17:11 +0800	[thread overview]
Message-ID: <20240517061713.95803-2-hal.feng@starfivetech.com> (raw)
In-Reply-To: <20240517061713.95803-1-hal.feng@starfivetech.com>

The UART of StarFive JH7110 has two reset signals.
Both of them are necessary for JH7110 to initialize UART.
