I have ran checkpatch on all 6 patches. I did not think this warning
needed a fix. Can I have your Ack-by if I fix the warning?

Commit bb691ae464b77d30e74c66480e98d74e88d6b194 breaks boot on OLPC XO-4,
it hangs somewhere inside sdhci_add_host.
When pm_runtime_set_autosuspend_delay() was being called, the device's usage
counter was 0, causing the PM layer to runtime-suspend the device. We then
went on to call sdhci_add_host
Hi,
Testing the latest linus kernel on OLPC XO-4 (sdhci-pxav3), boot

This patch adds support of recognizing non-removable cards
to Freescale's SDHC host driver. This is done by detecting the
attribute "non-removable" in the probe function
This patch depends on patch[2/3] from 6-jun-2013:

This patch is instead of patch[3/
Hi All,
Just noticed that 3.4.47/8 doesn't have the mmc_of_parse (compared to
3.9.4).
Therefore, I will not use it and just fix the code to recognize the
property "non-removable"
Best regards,

In suspend mode it is important to save power. If the host is able to
cut buth vcc and vccq, the MMC_CAP2_POWEROFF_NOTIFY shall be set. It
will mean the card will be completely powered down at suspend and the
power off notification cmd will be sent prior power down.
It seems co
From: Ulf Hansson
Depending on the context of the operation while powering down the card,
either POWER_OFF_NOTIFY_SHORT or POWER_OFF_NOTIFY_LONG will be used. In
suspend context a short timeout is preferred while a long timeout would
be acceptable in a shutdown/hibernation context.

Considering shutdown of the card, the responsibility to initate this
sequence shall be driven from the mmc_bus.
This patch enables the mmc_bus to handle this sequence properly. A new
.shutdown callback is added in the mmc_driver struct which is used to
shutdown the blk device.
From: Ulf Hansson
For every bus_ops type the .remove callback always exist, thus there
are no need to check the existence of it, before we decide to call it.

The host should be responsible to suspend|resume the host and not the

The MMC/SD/SDIO cards are registered on the mmc_bus and should from a power

Hi Dirk,
You are absolutely right.
I will revise my patch series to reflect the change.
Basically, I will call the generic mmc_of_parse from the probe function
of Freescale's driver.
That will handle all the additional capabilities.
