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.
Ok, I was wondering why it didn't happen on other JZ4725B devices, it
turns out they all use NAND + mmc1, and mmc0 is unused.
Can you confirm that the MMC0 controller will work even with the bit 6
off?
Do you know if the MMC0 bit has been moved elsewhere, or the MMC0
controller is permanently enabled?
Cheers,
