clocksource: sh_mtu2: Set initcall level to subsys

2013-03-12T17:24:37+00:00

The reason for this is to ensure that MTU2 is probed earlier
than with its previous initcall level, module init.

This came up as a problem with using CMT as a clock source kzm9g-reference
which does not make use of early timers or devices. In that scenario
initialisation of SDHI and MMCIF both stall on msleep() calls due to the
absence of a initialised clock source.

The purpose of this change is to keep the MTU2 code in sync with the CMT code
which has been modified in a similar manner..

Compile tested only using se7206_defconfig.
I do not believe I have any boards that support the MTU2.

Drivers: clocksource: remove __dev* attributes.

2013-01-03T23:57:15+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

sh: MTU2: Basic runtime PM support

2012-09-03T23:36:05+00:00

Modify the SH MTU2 clock event device driver to support runtime PM at
a basic level (i.e. device clocks can be disabled and enabled, but
domain power must be on, because the device has to be marked as
"irq safe").

PM / Domains: Move syscore flag from subsys data to struct device

2012-09-03T23:36:04+00:00

The syscore device PM flag is used to mark the devices (belonging to
a PM domain) that should never be turned off, except for the system
core (syscore) suspend/hibernation and resume stages.  That flag is
stored in the device's struct pm_subsys_data object whose address is
available from struct device.  However, in some situations it may be
convenient to set that flag before the device is added to a PM
domain, so it is better to move it directly to the "power" member of
struct device.  Then, it can be checked by the routines in
drivers/base/power/runtime.c and drivers/base/power/main.c, which is
more straightforward.

This also reduces the number of dev_gpd_data() invocations in the
generic PM domains framework, so the overhead related to the syscore
flag is slightly smaller.

PM / Domains: Rename the always_on device flag to syscore

2012-09-03T23:36:03+00:00

The always_on device flag is used to mark the devices (belonging to
a PM domain) that should never be turned off, except for the system
core (syscore) suspend/hibernation and resume stages.  Change name
of that flag to "syscore" to better reflect its purpose.

sh: MTU2: Introduce clock events suspend/resume routines

2012-09-03T23:36:02+00:00

Introduce suspend/resume routines for SH MTU2 clock event devices
such that if those devices belong to a PM domain, the generic PM
domains framework will be notified that the given domain may be
turned off (during system suspend) or that it has to be turned on
(during system resume).

PM / shmobile: Make MTU2 driver use pm_genpd_dev_always_on()

2012-03-16T20:45:26+00:00

Make the MTU2 clocksource driver mark its device as "always on"
using pm_genpd_dev_always_on() to protect it from surprise power
removals.

drivers/clocksource: Add module.h to those who were using it implicitly

2011-10-31T23:31:42+00:00

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in clocksource
are actually calling out for  explicitly in advance.

ARM: shmobile: remove sh_timer_config clk member

2010-10-31T14:40:39+00:00

Now when the SH-Mobile ARM platforms have been converted
to use device name it is possible to remove "clk" from
struct sh_timer_config.
