AR9374 v1.3 (Ath6kl - 6004) in sdio mode

AR9374 v1.3 (Ath6kl - 6004) in sdio mode

[drwho]

Can anyone confirm if they have had an AR9374 v1.3 (=AR6004) working in
sdio mode in compat v3.8?  I have three AR9374s working just fine in USB
mode with compat v3.8.  I have an AR6103 (=AR6003), sdio, working on the
same host as I'm trying the AR9374 on.  The AR9374 only gets as far as
registering as mmc1.  The vendor and device IDs are correct.  When I try
to load ath6kl_sdio, I get....

ath6kl: 8f69fe04
ath6kl: 8f69fe34
ath6kl: 8f69fe7c
ath6kl_sdio: probe of mmc1:0001:1 failed with error -110

loading ath6kl_core.ko debug_mask=0xffffffff doesn't give much more. 
compat is build with
export CONFIG_ATH_DEBUG=y
export CONFIG_ATH6KL_DEBUG=y
and I'm getting tones on debug when booting the AR6103.

My hardware settings for usb or sdio mode on the AR9374....

USB mode
sdio_cmd = 10k pull down

SDIO mode
sdio_cmd = 10k pull up to 3.3v
sdio_D1 = 10k pull up to 3.3v

I've tried dropping my sdio clock from 50Mhz to 10Mhz,  no go either.

Sounds like a hardware problem but difficult to say for sure. From
ath6kl point of view ar6003 and ar6004/ar9374 are not that different, at
least not that early on hardware initialisation.
