Subject: [PATCH v2 3/5] dt-bindings: riscv: d requires f
Date: Thu, 24 Oct 2024 13:34:31 +0100 [thread overview]
Message-ID: <20241024-petted-oasis-426993b07f75@spud> (raw)
In-Reply-To: <20241024-fanning-enrage-bcc39f8ed47d@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-precision floating
point. Add that requirement to the bindings. This differs from the
Linux implementation, where single-precious only is not supported.
