| Subject | [PATCH v2 5/5] Documentation/devicetree/bindings: Add FSI device documentation |
| Message-ID | <u00bE-3nZ-15@gated-at.bofh.it> |
From: "Edward A. James" <eajames@us.ibm.com>
Document the bindings for the SBE and OCC devices. SBE devices are
located on a CFAM on an FSI bus, and OCC devices are accessed through
the SBEFIFO.
