[PATCH v2] mmc: sdhci-msm: Optionally wait for signal level changes

2017-11-20 Thread Bjorn Andersson
Not all instances of the SDCC core supports changing signal voltage and as such will not generate a power interrupt when the software attempts to change the voltage. This results in probing the eMMC on some devices to take over 2 minutes. Check that the SWITCHABLE_SIGNALING_VOLTAGE bit in MCI_GENE
