From: Lubomir Rintel lkundrak@v3.sk Date: Thu, 14 Feb 2019 00:06:18 +0100 Subject: [PATCH] gpio: pxa: avoid attempting to set pin direction via pinctrl on MMP2
Similarly to PXA3xx, pinctrl-single can't set pin direction on MMP2 either. See also: commit 9dabfdd84bdfa ("gpio: pxa: disable pinctrl calls for PXA3xx")
