Subject: [net-next PATCH v4 4/4] octeontx2-pf: Move shared APIs to header file
Date: Wed, 23 Oct 2024 21:48:43 +0530 [thread overview]
Message-ID: <20241023161843.15543-5-gakula@marvell.com> (raw)
In-Reply-To: <20241023161843.15543-1-gakula@marvell.com>
Move mbox, hw resources and interrupt configuration functions to common
header file. So, that they can be used later by the RVU representor driver.
Signed-off-by: Geetha sowjanya <gakula@marvell.com>
