+Subject: [PATCH] fix-glamo-mci-ensure-more-than-74-clocks-after-power.patch
+
+We are meant to run SD_CLK a little while after power-on for the SD
+Card, but with the no idle clock changes we didn't take care about it.
+
+This makes us sleep a little bit before disabling clock if we just
+powered up the SD Card.
