Subject: [PATCH 1/2] bindings: ipmi: Add alert GPIO enhancement for SSIF BMC driver
Date: Sat, 19 Oct 2024 23:38:04 +0800 [thread overview]
Message-ID: <20241019-ssif-alert-gpios-v1-1-483eee5f99d3@gmail.com> (raw)
In-Reply-To: <20241019-ssif-alert-gpios-v1-0-483eee5f99d3@gmail.com>
Introduce the `alert-gpios` property to define an alert pin, enabling
the BMC to notify the host when a response is available.
