we don't need to do the check again in the platform device driver.
And the check in the current code is useless even if we really
run into a disabled device. In this case, it just doesn't parse
the dtb for the infos such as quirks or clock, but it will continue
to try to init the disabled device after that check. So just remove it.

Mobile phones (some) have no card detect pin, but can detect if the
cover is removed. The purpose is the same; detect if card is being
added/removed, but the details differ.
When the cover is removed, it does not mean the card is gone. But it
might, since it is accessible now. It's like a warning. All the driver
does is to limit write access to the card, see protect_card flag.
In contrast, card detect notifies us after the fact, e.g.
card is gone, card is inserted. We can't take precautions, but we can
rely on those events, -- the card is really gone, or do scan the card.
To summarize there is not much code sharing between cover and card
detect, it only increases confusion. By splitting, both will be
simplified in a followup patch.

For the original tuning code, delay value is set to SD Bus Clock Delay

which means CLK_DELAY_IN1, CLK_DELAY_IN2 and CLK_DELAY_OUT are the

We really don't want to get a card detect interrupt during probe time
since it can confuse things. Let's disable the card detect interrupt
until we're in a really good place: the end of probe. Let's also
simply avoid enabling the card detect interrupt if it's not used.
It appears that (at least on rk3288) when vqmmc is turned on it can
cause a bogus "card detect" interrupt. That meant that we were
getting a predictable card detect interrupt while we were in
mmc_add_host(). On the version of the kernel I'm working with at
least (3.14), this is not a great time to get a card detect interrupt
since I think that we don't grab all the needed locks in
mmc_add_host() and children. I put stack dumps in dw_mci_setup_bus()
and found that I could see two distinct stack crawls that looked like:
Caller one:
* dw_mci_setup_bus
* dw_mci_set_ios
* mmc_power_up
* mmc_start_host
* mmc_add_host
Caller two:
* dw_mci_setup_bus
* dw_mci_set_ios
* mmc_set_chip_select
* mmc_go_idle
* mmc_rescan
* process_one_work
* worker_thread

We've seen problems on some WiFi modules where we seem to send a CMD53
(which requires the data lines) while the module is asserting busy.
We shouldn't do that.
The Designware Databook says that before issuing a new data transfer
command we should check for busy, so that's what we'll do.
We'll leverage the existing dw_mmc knowledge about whether it should
wait for the previous command to finish to know whether we should
check for busy before sending the command. This means we won't end up
incorrectly waiting for things like CMD52 (SDIO) or CMD13 (SD) which
don't use the data line.
Note that this also has the advantage of making sure that we don't
change the clock while the card is busy, too.

To support HS200 and UHS mode, mmc core will call init_card() to
execute tuning:
- sdio: init_card can be executed at runtime resume.
- sd and mmc: init_card can be executed at resume or runtime resume,
which depends on MMC_CAP_RUNTIME_RESUME capability.
On rk3288 SoC, host will get DRTO interrupt when host send command
to read tuning data. This will spend more than 111ms:
drto_ms = drto_clks * 1000 / bus_hz = 111ms.
And the total tuning time will be more than 400ms.
So we should add MMC_CAP_RUNTIME_RESUME capability to execute tuning
at runtime resume. Only if we do so, can we pass resume test.

- Revert a recent PCI commit related to IRQ resources management
that introduced a regression for drivers attempting to bind to
devices whose previous drivers did not balance pci_enable_device()
and pci_disable_device() as expected (Rafael J Wysocki).
- Fix a deadlock in at91_rtc_interrupt() introduced by a typo in a
recent commit related to wakeup interrupt handling (Dan Carpenter).
- Allow the power capping RAPL (Running-Average Power Limit) driver
to use different energy units for domains within one CPU package
which is necessary to handle Intel Haswell EP processors correctly
(Jacob Pan).
- Improve the cpuidle mvebu driver's handling of Armada XP SoCs by
updating the target residency and exit latency numbers for those
chips (Sebastien Rannou).
- Prevent the cpuidle mvebu driver from calling cpu_pm_enter() twice
in a row before cpu_pm_exit() is called on the same CPU which
breaks the core's assumptions regarding the usage of those
functions (Gregory Clement).

Pull power management and ACPI fixes from Rafael Wysocki:
"These are fixes for recent regressions (PCI/ACPI resources and at91
RTC locking), a stable-candidate powercap RAPL driver fix and two ARM
cpuidle fixes (one stable-candidate too).

introduced a regression for drivers attempting to bind to devices
whose previous drivers did not balance pci_enable_device() and
pci_disable_device() as expected (Rafael J Wysocki).
