Hi David,

These patches add support for SDIO cards to the omap_hsmmc driver.
Power management changes to prevent SDIO cards from being turned
off
and losing all state, and card interrupts.
I've been unable to test these exact patches as I only have an
N900
for
testing and the N900 support in mainline is incomplete.
Changes since v1:
- (hopefully) get all cards working again by removing a second
call
to
read MMCi_STAT in the interrupt handler.
- flush posted writes after enabling/disabling SDIO interrupts.
- tweak the FIXME commit on disabling FCLK to better match what
really
going on (at least I think so anyway).
David Vrabel (2):
mmc: omap_hsmmc: don't turn SDIO cards off when idle
mmc: omap_hsmmc: enable SDIO card interrupts
Looks like this patchset wasn't merged. Mike Rapoport replied with
a
fix
for libertas. Would you like to resubmit it?
I thought Madhu had picked this up and was going to submit it.
Regardless of whether that is the case, I think it needs to be
submitted
by someone who can run mainline kernels (I can't) and ideally
someone
who can test it with SDIO cards.
I'll try to update the patches in the next few days.
Any update on the status of these patches? I'm happy to help test!
Steve,
I have not been able to test SDIO card interrupts. If you could help
test
that it's great.
Where can I grab the most recent patches? The original set don't apply
cleanly.
Yes. They may not apply. I can rebase them and send it to you for testing.
Are you using the two patches posted by David Vrabel?
Yes, I've been using the original patches on 2.6.33 and 2.6.34. The
SDIO interrupt patch doesn't apply on 2.6.35 or 36.
If you send a revised patch for either I would be happy to test as
soon as I get it.
I've tried to update the patches on top of 2.6.36-rc3 and I've got stuck.
The changes Adrian has made to the interrupt synchronization affect the way the
SDIO irq should be implemented and I haven't found a way to resolve it :-(
Steve
