From 6431862acdf288c404200350c2d1f21c794ee38d Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Fri, 9 Aug 2019 13:59:45 +0530 Subject: [PATCH] arm64: dts: ti: k3-j721e-common-proc-board: Disable unused gpio modules There are 10 gpio instances inside SoC with 3 groups as below: - Group1: main_gpio0, main_gpio2, main_gpio4, main_gpio6 - Group2: main_gpio1, main_gpio3, main_gpio5, main_gpio7 - Group3: wkup_gpio0, wkup_gpio1 Only one instance can be used in each group at a time. So use main_gpio0, main_gpio1 and wkup_gpio0 for the current linux context and mark other gpio nodes as disabled.
