I modified [1] your patch #2 to do what Alim suggested and only with
that patch on top of linux-next I have neither the the "Timeout
sending command" error nor the uSD not getting detected errors. Linux
mounts the rootfs from the uSD and the wifi SDIO device is enumerated
and listed in /sys/bus/sdio/devices/

it needs to check when clock value only update.
As Javier and Alim are mentioned, if check whether card is busy or not in setup_bus(),
should be processed unnecessary checking.
(According to TRM, before disabling clock, check whether card is busy or not.)
if my thinking is right, chekcing is located more exactly before mci_writel(host, CLKENA, 0).

And i recommend if CLK_GATE is enabled, clkgate_delay sets to the bigger value than 3.
I'm not sure Javier's issue is same thing..I will check more this.

Thanks for checking, do you have access to a Peach Pit or Pi
Chromebook to reproduce the issue I reported? Please let me know if
you need any help from me.

Best Regards,
Jaehoon Chung
