mmc: core: Fixup broken suspend and eMMC4.5 power off notify

2012-10-07T21:41:45+00:00

This patch fixes up the broken suspend sequence for eMMC with sleep
support. Additionally it reworks the eMMC4.5 Power Off Notification
feature so it fits together with the existing sleep feature.

The CMD0 based re-initialization of the eMMC at resume is re-introduced
to maintain compatiblity for devices using sleep.

A host shall use MMC_CAP2_POWEROFF_NOTIFY to enable the Power Off
Notification feature. We might be able to remove this cap later on,
if we think that Power Off Notification always is preferred over
sleep, even if the host is not able to cut the eMMC VCCQ power.

mmc: sd: Fix sd current limit setting

2012-07-22T19:25:52+00:00

Host has different current capabilities at different voltages, we need
to record these settings seperately. The defined voltages are 1.8/3.0/3.3.
For other voltages, we do not touch current limit setting.

Before we set the current limit for the sd card, find out the host's
operating voltage first and then find out the current capabilities of
the host at that voltage to set the current limit.

mmc: add two capability flags for CD and WP signal polarity

2012-07-21T04:02:16+00:00

To handle CD and WP SD/MMC slot pins we need generic flags to specify their
polarity.

mmc: core: use a more generic name for slot function types and fields

2012-07-21T04:02:16+00:00

struct mmc_host::hotplug is becoming a generic hook for slot functions.
Rename it accordingly.

mmc: add a function to get regulators, supplying card's power

2012-07-21T04:02:08+00:00

Add a function to get regulators, supplying card's Vdd and Vccq on a
specific host. If a Vdd supplying regulator is found, the function checks,
whether a valid OCR mask can be obtained from it. The Vccq regulator is
optional. A failure to get it is not fatal.

mmc: sdio: avoid spurious calls to interrupt handlers

2012-04-22T15:17:28+00:00

Commit 06e8935feb ("optimized SDIO IRQ handling for single irq")
introduced some spurious calls to SDIO function interrupt handlers,
such as when the SDIO IRQ thread is started, or the safety check
performed upon a system resume.  Let's add a flag to perform the
optimization only when a real interrupt is signaled by the host
driver and we know there is no point confirming it.

Merge tag 'mmc-merge-for-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

2012-03-29T03:59:45+00:00

Pull MMC updates from Chris Ball:

Core:
* Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices
that support Data Tag will provide increased throughput for metadata.
* Faster detection of card removal on I/O errors.

Drivers:
* dw_mmc now supports eMMC Power Off Notify, has PCI support, and
implements pre_req and post_req for asynchronous requests.
* omap_hsmmc now supports device tree.
* esdhc now has power management support.
* sdhci-tegra now supports Tegra30 devices.
* sdhci-spear now supports hibernation.
* tmio_mmc now supports using a GPIO for card detection.
* Intel PCH now supports 8-bit bus transfers.
