From 534d813a06202c565b4a7e75a3e710db7155e6d3 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Wed, 12 Mar 2025 13:11:47 +0000 Subject: [PATCH] dt-bindings: riscv: d requires f MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
