Subject: [PATCH v3 3/3] dt-bindings: serial: Add binding for software flow control in STM32 UART
Date: Wed, 15 Apr 2020 00:11:47 +0530	[thread overview]
Message-ID: <20200414184147.4857-4-mani@kernel.org> (raw)
In-Reply-To: <20200414184147.4857-1-mani@kernel.org>

From: Manivannan Sadhasivam <mani@kernel.org>

Add devicetree binding for software flow control in STM32 UART
controller. While at it, let's also fix one schema error reported by
`make dtbs_check`.
