Subject: [PATCH 1/2] bindings: ipmi: ssif-bmc: Add property to adjust response timeout
Date: Mon, 03 Feb 2025 21:09:13 +0800 [thread overview]
Message-ID: <20250203-ssif-response-timeout-ms-v1-1-6fe279740181@gmail.com> (raw)
In-Reply-To: <20250203-ssif-response-timeout-ms-v1-0-6fe279740181@gmail.com>
The SSIF response is handled by a userspace application, which may exceed
the default 500 ms timeout when the BMC or application is under heavy load.
Add a new device tree property, `timeout-ms`, allowing platforms to adjust
the response timeout based on their specific requirements. This helps
prevent timeouts in scenarios where longer processing times are expected.
