POWERPC: drivers: remove __dev* attributes.

2013-01-03T23:57:04+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.

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

2012-12-18T17:58:09+00:00

Pull powerpc update from Benjamin Herrenschmidt:
 "The main highlight is probably some base POWER8 support.  There's more
  to come such as transactional memory support but that will wait for
  the next one.

  Overall it's pretty quiet, or rather I've been pretty poor at picking
  things up from patchwork and reviewing them this time around and Kumar
  no better on the FSL side it seems..."

powerpc/fsl-pci: Add PCI controller ATMU PM support

2012-11-25T13:00:28+00:00

Power supply for PCI controller ATMU registers is off when system go to
deep-sleep state. So ATMU registers should be re-setup during PCI
controllers resume from sleep.

drivers/of: Constify device_node->name and ->path_component_name

2012-11-17T12:05:57+00:00

Neither of these should ever be changed once set. Make them const and
fix up the users that try to modify it in-place. In one case
kmalloc+memcpy is replaced with kstrdup() to avoid modifying the string.

Build tested with defconfigs on ARM, PowerPC, Sparc, MIPS, x86 among
others.

powerpc/fsl-pci: use 'Header Type' to identify PCIE mode

2012-09-27T12:31:58+00:00

The original code uses 'Programming Interface' field to judge if PCIE is
EP or RC mode, however, some latest silicons do not support this
functionality.  According to PCIE specification, 'Header Type' offset 0x0e
is used to indicate header type, so change code to use 'Header Type' field
to judge PCIE mode. Because FSL PCI controller does not support
'Header Type', patch still uses 'Programming Interface' to identify PCI
mode.

powerpc/fsl-pci: Unify pci/pcie initialization code

2012-09-12T19:57:12+00:00

We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.

Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

powerpc/pci: Use PCIe IP block revision register instead of compatible

2012-09-12T19:57:12+00:00

Freescale PCIe IP block revision bigger than rev2.2 will also need
redefine the sequence of inbound windows. So change to use IP block
revision instead of compatible for the judgment.

powerpc/swiotlb: Enable at early stage and disable if not necessary

2012-09-12T19:57:09+00:00

Remove the dependency on PCI initialization for SWIOTLB initialization.
So that PCI can be initialized at proper time.

SWIOTLB is partly determined by PCI inbound/outbound map which is assigned
in PCI initialization. But swiotlb_init() should be done at the stage of
mem_init() which is much earlier than PCI initialization. So we reserve the
memory for SWIOTLB first and free it if not necessary.

All boards are converted to fit this change.
