From 70942db4dd1c5f177ea750df301d5b80c1fc15dc Mon Sep 17 00:00:00 2001 From: Andreas Dannenberg Date: Tue, 4 Jun 2019 17:55:44 -0500 Subject: [PATCH] mmc: am654_sdhci: Allow driver to probe without PDs specified We would like to use the driver even without power domains being specified for cases such as during early boot when the required power domains have already gotten enabled by the SoC's boot ROM and such explicit initialization is not needed and possible.
