Subject: [PATCH v2 1/2] dt-bindings: soc: renesas: mfis: add R-Car V4H/V4M support
Date: Tue, 19 May 2026 09:56:18 +0200 [thread overview]
Message-ID: <20260519075620.4128-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20260519075620.4128-1-wsa+renesas@sang-engineering.com>
The above SoCs have only 12 mailboxes and do not have an extra register
space for mailboxes. Everything is contained in the common register set.
In addition to adding these SoCs, the other entries get updated to
enforce 2 register spaces and their specific number of interrupts.
