Subject: [PATCH v4 02/17] dt-bindings: fsi: fsi2spi: Document SPI controller child nodes
Date: Mon, 29 Apr 2024 16:01:16 -0500 [thread overview]
Message-ID: <20240429210131.373487-3-eajames@linux.ibm.com> (raw)
In-Reply-To: <20240429210131.373487-1-eajames@linux.ibm.com>
The FSI2SPI bridge has several SPI controllers behind it, which
should be documented. Also, therefore the node needs to specify
address and size cells.
