Subject: [RESEND PATCH v16 mfd 3/8] pinctrl: ocelot: add ability to be used in a non-mmio configuration
Date: Mon, 5 Sep 2022 09:21:27 -0700 [thread overview]
Message-ID: <20220905162132.2943088-4-colin.foster@in-advantage.com> (raw)
In-Reply-To: <20220905162132.2943088-1-colin.foster@in-advantage.com>
There are a few Ocelot chips that contain pinctrl logic, but can be
controlled externally. Specifically the VSC7511, 7512, 7513 and 7514. In
the externally controlled configurations these registers are not
memory-mapped.
Add support for these non-memory-mapped configurations.
