commit 2f0754f27a230fee6e6d753f07585cee03bedfe3 upstream.
The mmc0 clock gate bit was mistakenly assigned to "i2s" clock. You can find that the same bit is assigned to "mmc0" too. It leads to mmc0 hang for a long time after any sound activity also it prevented PM_SLEEP to work properly. I guess it was introduced by copy-paste from jz4740 driver where it is really controls I2S clock gate.
