From aed13186898f348876c9fd705e910b823652e67b Mon Sep 17 00:00:00 2001 From: Anirudh Ghayal Date: Tue, 22 May 2018 19:10:14 +0530 Subject: [PATCH] pinctrl: qcom: spmi-gpio: Fix the GPIO strength mapping The SPMI based PMICs have the HIGH and LOW GPIO output strength mappings interchanged, fix them. Keep the mapping same for older SSBI based PMICs.
