Subject: [PATCH 1/4] lib: utils/mailbox: Update DT register name of A2P doorbell
Date: Mon, 12 May 2025 14:08:24 +0530	[thread overview]
Message-ID: <20250512083827.804151-2-apatel@ventanamicro.com> (raw)
In-Reply-To: <20250512083827.804151-1-apatel@ventanamicro.com>

The latest device tree bindings define A2P doorbell register name as
"a2p-doorbell" so update rpmi_shmem_transport_init() accordingly.
