ata: constify of_device_id structures

2017-03-06T20:18:01+00:00

Declare of_device_id structures as const as they are either passed to
the macro MODULE_DEVICE_TABLE or stored in the of_match_table field of a
device_driver structure. This field is of type const, so of_device_id
structures having this property can be made const too.

Cross compiled the files drivers/ata/pata_macio.c and
drivers/ata/pata_mpc52xx.c for powerpc architecture.

ata: drop owner assignment from platform_drivers

2014-10-20T14:20:17+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

2014-05-10T02:37:49+00:00

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM
where applicable.  Benefits of this change:

* unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n
  and CONFIG_PM_RUNTIME=y configurations

* easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in
  the future

* more consistent code (there are host drivers which are using the correct
  CONFIG_PM_SLEEP checks already)

The patch leaves the core libata code and ->port_[suspend,resume] support
in sata_[inic162x,nv,sil24].c alone for now.

ata: use platform_{get,set}_drvdata()

2013-05-24T01:26:13+00:00

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.

Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

Merge remote-tracking branch 'agust/next' into next

2013-02-20T00:39:05+00:00

<<
Please pull mpc5xxx patches for v3.9. The bestcomm driver is
moved to drivers/dma (so it will be usable for ColdFire).
mpc5121 now provides common dtsi file and existing mpc5121 device
trees use it. There are some minor clock init and sparse fixes
and updates for various 5200 device tree files from Grant. Some
fixes for bugs in the mpc5121 DIU driver are also included here
(Andrew Morton suggested to push them via my mpc5xxx tree).

Drivers: ata: remove __dev* attributes.

2013-01-03T23:57:03+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,
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.

powerpc, dma: move bestcomm driver from arch/powerpc/sysdev to drivers/dma

2013-01-03T14:41:20+00:00

The bestcomm dma hardware, and some of its users like the FEC ethernet
component, is used in different FreeScale parts, including non-powerpc
parts like the ColdFire MCF547x & MCF548x families.  Don't keep the
driver hidden in arch/powerpc where it is inaccessible for other arches.
.c files are moved to drivers/dma/bestcomm, while .h files are moved to
include/linux/fsl/bestcomm.  Makefiles, Kconfigs and #include directives
are updated for the new file locations.

Tested by recompiling for MPC5200 with all bestcomm users enabled.

drivers/ata/pata_mpc52xx.c: clean up error handling code

2012-03-13T20:41:08+00:00

This patch makes a number of changes with respect to the error-handling
code:

* Remove cleanup calls for the devm functions in both the error handling
  code and the remove function.  This cleanup is done automatically.

* The previous change simplifies the cleanup code at the end of the
  function such that there is nothing to do on the failure of the call to
  devm_ioremap.  So it is changed to just return directly.

* There is no need for the ifs in the cleanup code at the end of the
  function, because in each case the cleanup needed is statically
  known.  Drop the ifs, add new err labels, and drop the initializations of
  the tested variables to NULL.

* Change the call to request_irq to a call to devm_request_irq, so that it
  is cleaned up on exit.

* Cause the return value of devm_request_irq to go into the returned
  variable rv rather than the unused variable ret.  Drop ret.
