From 894ad61b85d6ba8efd4274aa8719d9ff1c89ea54 Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Fri, 23 Feb 2024 20:14:39 +0200 Subject: mmc: omap: restore original power up/down steps Commit e519f0bb64ef ("ARM/mmc: Convert old mmci-omap to GPIO descriptors") moved Nokia N810 MMC power up/down from the board file into the MMC driver. The change removed some delays, and ordering without a valid reason. Restore power up/down to match the original code. This matters only on N810 where the 2nd GPIO is in use. Other boards will see an additional delay but that should be a lesser concern than omitting delays altogether.
