Subject: [PATCH v4 01/17] spi: dt-bindings: Document the IBM FSI-attached SPI controller
Date: Mon, 29 Apr 2024 16:01:15 -0500 [thread overview]
Message-ID: <20240429210131.373487-2-eajames@linux.ibm.com> (raw)
In-Reply-To: <20240429210131.373487-1-eajames@linux.ibm.com>
IBM Power processors have a SPI controller that can be accessed
over FSI from a service processor. Document it.
Signed-off-by: Eddie James <eajames@linux.ibm.com>

Changes since v2:
- Change name from ibm,p10-spi to ibm,spi-fsi for two reasons. One, this
matches the I2C controller binding (ibm,i2c-fsi), and two, this binding
is specifically for the FSI-attached SPI controllers on the P10 but
accessed from the service processor. P10 SPI controllers accessed from
the P10 would have different bindings.
- Fix warnings by using generic FSI parent node
- Fix prefix
