Subject: [RFC v1 net-next 5/7] net: dsa: felix: attempt to initialize internal hsio plls
Date: Wed, 15 Feb 2023 23:53:19 -0800 [thread overview]
Message-ID: <20230216075321.2898003-6-colin.foster@in-advantage.com> (raw)
In-Reply-To: <20230216075321.2898003-1-colin.foster@in-advantage.com>
The VSC7512 and VSC7514 have internal PLLs that can be used to control
different peripherals. Initialize these high speed I/O (HSIO) PLLs when
they exist, so that dependent peripherals like QSGMII can function.
