Subject: [RFC v1 3/5] dt-bindings: riscv: d requires f
Date: Wed, 2 Oct 2024 17:10:56 +0100 [thread overview]
Message-ID: <20241002-deliverer-recite-2c5a05f50721@spud> (raw)
In-Reply-To: <20241002-defeat-pavestone-73d712895f0b@spud>
From: Conor Dooley <conor.dooley@microchip.com>
Per the specifications, the d extension for double-precision floating
point operations depends on the f extension for single-precious floating
point. Add that requirement to the bindings. This differs from the
Linux implementation, where single-precious only is not supported.
