From: Andrew Jones Date: Mon, 30 Jan 2023 13:01:24 +0100 Subject: [PATCH v3 2/6] dt-bindings: riscv: Document cboz-block-size In-Reply-To: <20230130120128.1349464-1-ajones@ventanamicro.com> References: <20230130120128.1349464-1-ajones@ventanamicro.com> Message-ID: <20230130120128.1349464-3-ajones@ventanamicro.com> List-Id: To: kvm-riscv@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit 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 specified. Create another property specifically for Zicboz.
