Subject: [RFC PATCH v2 02/10] firmware: arm_scmi: Document that max_msg is a per channel type limit
Date: Thu, 5 Nov 2020 22:21:08 +0100 [thread overview]
Message-ID: <20201105212116.411422-3-peter.hilber@opensynergy.com> (raw)
In-Reply-To: <20201105212116.411422-1-peter.hilber@opensynergy.com>
From: Igor Skalkin <igor.skalkin@opensynergy.com>
struct scmi_desc.max_msg specifies a limit for the pending messages.
This limit is a per SCMI channel type (tx, rx) limit. State that
explicitly in the inline documentation. The following patch will add an
op to override the limit per channel type.
