Conor Dooley <conor@kernel.org> says: From: Conor Dooley <conor.dooley@microchip.com> Yo, This series is partly leveraging Clement's work adding a validate callback in the extension detection code so that things like checking for whether a vector crypto extension is usable can be done like: has_extension(<vector crypto>) rather than has_vector() && has_extension(<vector crypto>) which Eric pointed out was a poor design some months ago. The rest of this is adding some requirements to the bindings that prevent combinations of extensions disallowed by the ISA. There's a bunch of over-long lines in here, but I thought that the over-long lines were clearer than breaking them up. Cheers, Conor. * patches from https://lore.kernel.org/r/20250312-abide-pancreas-3576b8c44d2c@spud: dt-bindings: riscv: document vector crypto requirements dt-bindings: riscv: add vector sub-extension dependencies dt-bindings: riscv: d requires f RISC-V: add f & d extension validation checks RISC-V: add vector crypto extension validation checks RISC-V: add vector extension validation checks Link: https://lore.kernel.org/r/20250312-abide-pancreas-3576b8c44d2c@spud Signed-off-by: Alexandre Ghiti <alexghiti@rivosinc.com>
