mmc: tmio: prevent endless loop in tmio_mmc_set_clock()

I spent a couple of days with the driver just hanging due to me forgetting to
specify the external crystal frequency,  so that clk_get_rate() returned 0 and
thus the loop in tmio_mmc_set_clock() never ended. I don't think that's an

mmc: tmio_mmc: Fixup system PM suspend lock-up

At system PM suspend, the tmio core accessed the internal registers of
the controller without first moving the device into active state. This
caused a lock-up in system PM suspend phase.

The reason for the register access were masking of IRQs. Since that is
managed via the runtime PM suspend path, let's just re-use that path
for system PM suspend.

In other words force the device into runtime PM suspend state at system
PM suspend and restore it to active state at system PM resume.

mmc: sdhi: Fixup system PM suspend lock-up

At system PM suspend, the tmio core accessed the internal registers of
the controller without first moving the device into active state. This
caused a lock-up in system PM suspend phase.

The reason for the register access were masking of IRQs. Since that is
managed via the runtime PM suspend path, let's just re-use that path
for system PM suspend.

In other words force the device into runtime PM suspend state at system
PM suspend and restore it to active state at system PM resume.

mmc: tmio: Restructure ->set_ios() and adapt ->probe() to it

An internal power state machine were beeing used to keep ->probe() and
->set_ios() in sync. Especially for handling specific scenarios while
using CONFIG_MMC_CLKGATE. Moreover dependency to CONFIG_MMC_CLKGATE
existed to handle runtime PM properly, which we moves away from here.

By removing the state machine and instead make ->set_ios() rely on the
information provided through the function's in-parameters, the code
becomes significantly simplier.

Additonally as a part of this rework we prepares for making the runtime

PM: Add pm_runtime_suspend|resume_force functions

This patch provides two new runtime PM helper functions which intend to
be used from system suspend/resume callbacks, to make sure devices are
put into low power state during system suspend and brought back to full
power at system resume.

The prerequisite is to have all levels of a device's runtime PM
callbacks to be defined through the SET_PM_RUNTIME_PM_OPS macro, which
means these are available for CONFIG_PM.

By using the new runtime PM helper functions especially the two
scenarios below will be addressed.

1) The PM core prevents .runtime_suspend callbacks from being invoked
during system suspend. That means even for a runtime PM centric
subsystem and driver, the device needs to be put into low power state
from a system suspend callback. Otherwise it may very well be left in
full power state (runtime resumed) while the system is suspended. By
using the new helper functions, we make sure to walk the hierarchy of
a device's power domain, subsystem and driver.

2) Subsystems and drivers need to cope with all the combinations of
CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. The two new helper functions
smothly addresses this.

mmc: Add .multi_io_quirk callback for multi I/O HW bug

Historically, we have been using MMC_CAP* to handle host HW issues and
currently the block layer uses MMC_CAP2_NO_MULTI_READ flag for a multi
I/O HW bug workaround.

There are a few tweaks needed to make MMC_CAP2_NO_MULTI_READ suite all
situations. Therefore let's add an optional host ops callback to enable
host drivers to return the number of blocks it allows per request.

In a future patch and when host drivers have converted to the new
callback, MMC_CAP2_NO_MULTI_READ shall be removed.

ASoC: rsnd: delete unneeded test before of_node_put

Of_node_put supports NULL as its argument, so the initial test is not
necessary.

Suggested by Uwe Kleine-König.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

expression e;

-if (e)

[media] of: move common endpoint parsing to drivers/of

This patch adds a new struct of_endpoint which is then embedded in struct
v4l2_of_endpoint and contains the endpoint properties that are not V4L2
(or even media) specific: the port number, endpoint id, local device tree
node and remote endpoint phandle. of_graph_parse_endpoint parses those
properties and is used by v4l2_of_parse_endpoint, which just adds the
V4L2 MBUS information to the containing v4l2_of_endpoint structure.
