From d2c05f50e12f87128597a28146de7092aaa847c3 Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Fri, 5 Apr 2019 14:18:46 +0530 Subject: [PATCH] mmc: omap_hsmmc: Set 3.3V for IO voltage Pbias voltage should match the IO voltage set for the SD card. With the latest pbias change to 3.3V, update the capabilities and IO voltages settings to 3.3V.
