Subject: [PATCH v2 4/5] dt-bindings: riscv: add vector sub-extension dependencies
From: Conor Dooley <conor.dooley@...rochip.com>
Section 33.18.2. Zve*: Vector Extensions for Embedded Processors
in [1] says:
| The Zve32f and Zve64x extensions depend on the Zve32x extension. The Zve64f extension depends
| on the Zve32f and Zve64x extensions. The Zve64d extension depends on the Zve64f extension
| The Zve32x extension depends on the Zicsr extension. The Zve32f and Zve64f extensions depend
| upon the F extension
| The Zve64d extension depends upon the D extension
Apply these rules to the bindings to help prevent invalid combinations.
