Since commit a483dcbfa21f919c ("ARM: shmobile: lager: Remove legacy
board support"), R-Car Gen2 SoCs are only supported in generic DT-only
ARM multi-platform builds.  The driver doesn't need to match platform
devices by name anymore, hence remove the corresponding
platform_device_id entry.

In order to make it possible to restore from hibernation not only in Linux but
also in e.g. U-Boot, we have to extend  sata_rcar_{suspend|resume}() to {freeze|
thaw}() PM  methods and implement  the  restore() PM method.

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

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

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.

R-Car Gen2 SoCs have a different PHY which is not compatible
with the older R-Car H1 (R8A7779) version.
This adds OF/platform device id tables and PHY initialization
callbacks for the following Gen2 SoCs:
  * R-Car H2: R8A7790;
  * R-Car M2: R8A7791.

PHY initialization method is chosen based on the device id.
Default PHY settings are applied for Gen2 SoCs, which should
suit the Gen2 boards available.

While at it, this also adds "sata-r8a7779" compatibility string
for R8A7779 SATA, while keeping the old one for compatibility.

clk_disable_unprepare() to get ready for the migration to the common

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;

- res = platform_get_resource(pdev, IORESOURCE_MEM, n);

  ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
