Subject: [dpdk-dev] [PATCH v2 01/32] common/cnxk: add bphy cgx/rpm initialization and cleanup
Date: Tue, 15 Jun 2021 13:03:14 +0200
Message-ID: <20210615110345.11057-2-tduszynski@marvell.com> (raw)
In-Reply-To: <20210615110345.11057-1-tduszynski@marvell.com>

Add support for low level initialization and cleanup of baseband
phy cgx/rpm blocks.

Initialization and cleanup are related hence are in the same patch.
