dt-bindings: fsi: Convert aspeed,ast2400-cf-fsi-master to DT schema

2025-08-11T13:10:40+00:00

Convert the ASpeed Coldfire offloaded GPIO FSI master. Drop the "fsi-master" compatible as it has not be used consistently and doesn't represent anything. Acked-by: Eddie James Link: https://lore.kernel.org/r/20250731-dt-fsi-cleanups-v1-6-e7b695a29fc3@kernel.org Signed-off-by: Rob Herring (Arm)

dt-bindings: fsi: Convert fsi-master-gpio to DT schema

2025-08-11T13:10:39+00:00

Convert the GPIO-based FSI master binding to DT schema format. Drop the "fsi-master" compatible as it has not be used consistently and doesn't represent anything.

dt-bindings: fsi: ibm,p9-scom: Add "ibm,fsi2pib" compatible

2025-03-12T01:02:13+00:00

The "ibm,fsi2pib" compatible was originally in the binding, but it changed to "ibm,p9-scom" in the end. However, both compatibles are in use, so just support both.

dt-bindings: fsi: Document the AST2700 FSI controller

2024-07-09T13:40:17+00:00

Add the appropriate compatible string, and document the new reg properties of the AST2700 FSI controller, which can directly access the FSI controller registers as well as the FSI link address space.

dt-bindings: fsi: ibm,i2cr-fsi-master: Reference common FSI controller

dt-bindings: fsi: Document the FSI controller common properties

2024-07-09T13:40:17+00:00

Since there are multiple FSI controllers documented, the common properties should be documented separately and then referenced from the specific controller documentation. Add bus-frequency for the FSI bus and CFAM local bus frequencies. Add interrupt controller properties.
