Subject: [PATCH V2 2/6] pinctrl: sprd: Fix the incorrect mask and shift definition
Date: Fri, 8 Sep 2023 13:51:42 +0800	[thread overview]
Message-ID: <20230908055146.18347-3-Linhua.xu@unisoc.com> (raw)
In-Reply-To: <20230908055146.18347-1-Linhua.xu@unisoc.com>

From: Linhua Xu <Linhua.Xu@unisoc.com>

Pull-up and pull-down are mutually exclusive. When setting one of them,
the bit of the other needs to be clear. Now, there are cases where pull-up
and pull-down are set at the same time in the code, thus fix them.
