Subject: [PATCH 3/4] dt-bindings: mailbox: tegra186-hsp: allow doorbell+shared or shared-only
Date: Wed, 25 Mar 2026 21:26:27 +0000 [thread overview]
Message-ID: <20260325212628.1234082-4-chunn@nvidia.com> (raw)
In-Reply-To: <20260325212628.1234082-1-chunn@nvidia.com>
On Tegra238, hsp_top0 mailbox has doorbell plus shared0, while hsp_top1
and aon_hsp mailboxes expose only a single shared interrupt (shared0 and
shared1 respectively) with no doorbell.
Update the schema to support Tegra238 by adding an extra oneOf options for:
- doorbell with one shared interrupt (shared0..shared15)
- single shared interrupt only (no doorbell)
