Subject: [PATCH 2/2] dt-bindings: riscv: fix single letter canonical order
Date: Thu, 24 Nov 2022 13:04:41 +0000	[thread overview]
Message-ID: <20221124130440.306771-3-conor.dooley@microchip.com> (raw)
In-Reply-To: <20221124130440.306771-1-conor.dooley@microchip.com>

I used the wikipedia table for ordering extensions when updating the
pattern here in foo.
Unfortunately that table did not match canonical order, as defined by
the RISC-V ISA Manual, which defines extension ordering in (what is
currently) Table 41, "Standard ISA extension names". Fix things up by
re-sorting v (vector) and adding p (packed-simd) & j (dynamic
languages). The e (reduced integer) and g (general) extensions are still
intentionally left out.
