Subject: [PATCH v5 05/10] i2c: npcm: Add tx complete counter
Date: Tue, 17 May 2022 18:11:37 +0800 [thread overview]
Message-ID: <20220517101142.28421-6-warp5tw@gmail.com> (raw)
In-Reply-To: <20220517101142.28421-1-warp5tw@gmail.com>
From: Tali Perry <tali.perry1@gmail.com>
tx_complete counter is used to indicate successful transaction
count.
Similar counters for failed tx were previously added.
