From: Anand Gadiyar <gadiyar@xxxxxx> The OMAP HSMMC driver uses an ocr_mask to determine the list of voltages supported by the card. It populates this mask based on the list of voltages supported by the regulator that supplies the voltage. Commit 64be97822b (omap4 hsmmc: Update ocr mask for MMC2 for regulator to use) passed a fixed ocr_mask from the OMAP4 SDP board file to limit the voltage to 2.9-3.0 Volts, and updated the driver to use this mask if provided, instead of using the regulator's supported voltages. However the commit is buggy - the ocr_mask is overridden by the regulator's capabilities anyway. Fix this. (The bug shows up when a system-wide suspend is attempted on the OMAP4 SDP/Blaze platforms. The eMMC card comes up at 3V, but drops to 1.65V after the system resumes).
