Subject: [PATCH 10/13 v2] ARM: ixp4xx: Remove feature bit accessors
Date: Fri, 11 Feb 2022 23:32:35 +0100	[thread overview]
Message-ID: <20220211223238.648934-11-linus.walleij@linaro.org> (raw)
In-Reply-To: <20220211223238.648934-1-linus.walleij@linaro.org>

We switched users of the accessors over to using syscon to inspect
the bits, or removed the need for checking them. Delete these
accessors.
