[PATCH 2/6] pinctrl: sprd: Fix the incorrect mask and shift definition
Posted by Linhua Xu 2 years, 5 months ago
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.
