Subject: [PATCH RFC 03/10] dt-bindings: arm: cpus: Add Cortina Systems CS7542 enable method
Date: Wed, 30 Sep 2026 10:00:02 +0300 [thread overview]
Message-ID: <20260930-b4-cs75xx-v1-3-4617c4463529@gmail.com> (raw)
In-Reply-To: <20260930-b4-cs75xx-v1-0-4617c4463529@gmail.com>
From: Fil Dunsky <filipp.dunsky@gmail.com>
On the CS7542 the bootloader parks the secondary Cortex-A9 core in a loop
that waits for an event and then jumps to the address found in a global
software register. Add the "cortina,cs7542-smp" enable method for it and,
as with the other release-address based methods, require cpu-release-addr
to point at that register.
