Subject: [PATCH v4 3/8] dt-bindings: riscv: Document cboz-block-size
Date: Thu, 9 Feb 2023 16:26:23 +0100 [thread overview]
Message-ID: <20230209152628.129914-4-ajones@ventanamicro.com> (raw)
In-Reply-To: <20230209152628.129914-1-ajones@ventanamicro.com>
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.
