Setting a dev_pm_ops suspend/resume pair but not a set of
hibernation functions means those pm functions will not be
called upon hibernation.
Fix this by using SET_SYSTEM_SLEEP_PM_OPS, which appropriately
assigns the suspend and hibernation handlers and move
omap_hsmmc_x callbacks under CONFIG_PM_SLEEP to avoid build warnings.

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.

The reset control for the sunxi mmc controller is optional. Some

(sun4i, sun5i, sun7i) don't.

Use the properly stubbed _optional version so the driver does not
fail to compile when RESET_CONTROLLER=n.

This patch also adds a check for deferred probing on the reset
control.

For the original tuning code, delay value is set to SD Bus Clock Delay
Register (SD_CLK_DELAY_SETTING) as (val | (Val << 7) | (val << 16)),
which means CLK_DELAY_IN1, CLK_DELAY_IN2 and CLK_DELAY_OUT are the
same and with 128 steps. This is doubtful. In CSR design specification
documents CS-304575-DR-3H, this issue is clarified, the delay[13:0] in
SD_CLK_DELAY_SETTING is simplied to the concatenation of {CLK_DELAY_IN2,
CLK_DELAY_IN1}.
Besides, for CMD19 tuning, no need to set CLK_DELAY_OUT([22,16]

It's unlikely that this is really needed on any single-slot systems
where we disable card detects until the end of probe, but it still
seems safer to check to make sure that a slot has been initted before
we try to dereference it to find the SDIO interrupt mask.

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
* kthread

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.
