From 70a2b4220e55105aa6c970589a6a96d2714751f4 Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Fri, 5 Mar 2021 10:22:26 +0800 Subject: pinctrl: mediatek: do not probe gpio driver if not enabled The mtk pinctrl driver is a combination driver with support for both pinctrl and gpio. When this driver is used in SPL, gpio support may not be enabled, and this will result in a compilation error. To fix this, macros are added to make sure gpio related code will only be compiled when gpio support is enabled.
