Subject: [PATCH v3 08/14] dt-bindings: mfd: atmel,sama5d2-flexcom: Add USART child node ref binding
Date: Tue, 13 Sep 2022 17:22:00 +0300	[thread overview]
Message-ID: <20220913142205.162399-9-sergiu.moga@microchip.com> (raw)
In-Reply-To: <20220913142205.162399-1-sergiu.moga@microchip.com>

FLEXCOM, among other functionalities, has the ability to offer the USART
serial communication protocol. To have the FLEXCOM binding properly
validate its USART children nodes, we must reference the correct binding.
To differentiate between the SPI of FLEXCOM and the SPI of USART in SPI
mode, use the compatible string.

Signed-off-by: Sergiu Moga <sergiu.moga@microchip.com>

v1 -> v2:
- Nothing


v2 -> v3:
- Previously [PATCH 7]
- Compare devices based on the compatible instead of the clock
