Subject[PATCH 01/12] dt-bindings: riscv: sifive-ccache: Add compatible for StarFive JH7100 SoC
Date
Document the compatible for the SiFive Composable Cache Controller found
on the StarFive JH7100 SoC.

This also requires extending the 'reg' property to handle distinct
ranges, as specified via 'reg-names'.
