From: Andrew Jones Date: Fri, 24 Feb 2023 16:26:26 +0000 (+0100) Subject: dt-bindings: riscv: Document cboz-block-size X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ea20f117ab99d7c7653df656ddb795e51d9f7733;p=linux.git dt-bindings: riscv: Document cboz-block-size The Zicboz operation (cbo.zero) operates on a block-size defined for the cpu-core. While we already have the riscv,cbom-block-size property, it only provides the block size for Zicbom operations. Even though it's likely Zicboz and Zicbom will use the same size, that's not required by the specification. Create another property specifically for Zicboz.
