Bhumika Goyal 0777066dce clk: make clk_init_data const
Make these const as they are only stored in the init field of a clk_hw
structure, which is const.

Stephen Boyd f5b3715ecf clk: twl6040: Migrate to clk_hw based registration APIs
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

Peter Ujfalusi 7e37deb7fa clk: twl6040: Rename the driver and use consistent names in the code
The driver is to provide the functional clock to OMAP4/5 McPDM. The clock
is named as pdmclk in the documentations so change the function names,
structure names and variables to align with this.
At the same time rename the driver from "twl6040-clk" to "twl6040-pdmclk".
This can be done w/o regression since the clock driver is not in use at
the moment, the MFD core driver is not even registering the device for it.

Peter Ujfalusi 994deaae37 clk: twl6040: Register the clock as of_clk_provider
In order ot be able to use the pdmclk clock via DT it need to be registered
as of_clk_provide.
Since the twl6040 clock driver does not have it's own DT node, use the
parent's node for registering.

Peter Ujfalusi 225ff4e87a clk: twl6040: Correct clk_ops
Since the drover only supports prepare callbacks, the use of is_enabled is
not correct, it should be handling is_prepared.

Stephen Boyd e873473cbc clk: twl6040: Remove clk.h include
Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver.

Kiran Padwal 59c0621d4d clk: Remove .owner field for driver
There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

Jingoo Han c0431037b4 clk: use platform_{get,set}_drvdata()
Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Greg Kroah-Hartman 0fe763c570 Drivers: misc: remove __dev* attributes.
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.

Wei Yongjun ddc07ef949 CLK: clk-twl6040: fix return value check in twl6040_clk_probe()
In case of error, the function clk_register() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

Peter Ujfalusi f9f8c0438d CLK: clk-twl6040: Initial clock driver for OMAP4+ McPDM fclk clock
On OMAP4+ platforms the functional clock for the McPDM IP is suplied by
the twl6040 codec (bit clock on the PDM bus).
This common clock driver for twl6040 will register the mcpdm_fclk clock to
be used by the McPDM driver to make sure that the needed clocks are
available when needed.
