sparc: Explicitly include correct DT includes

2023-08-28T18:30:57+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

sparc: Use of_property_present() for testing DT property presence

2023-04-18T16:23:21+00:00

It is preferred to use typed property access functions (i.e.
of_property_read_ functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

sparc32: use per-device dma_ops

2020-04-03T01:11:55+00:00

sparc32 is the last platform making dynamic decisions in
get_arch_dma_ops based on the bus passed in.  Instead set the
iommu dma_ops at iommu probing and propagate them in
of_propagate_archdata, falling back to the NULL ops for the
direct mapping in the Leon or PCI case.

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have EXPORT_.*_SYMBOL_GPL inside which was used in the
   initial scan/conversion to ignore the file

These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

  GPL-2.0-only

sparc: Use of_node_name_eq for node name comparisons

2018-11-18T21:35:21+00:00

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

sparc: fix sparse warnings in of_device_common.c

2014-04-29T05:12:27+00:00

Fix following warnings (both sparc32 and sparc64):
of_device_common.c:13:14: warning: symbol 'irq_of_parse_and_map' was not declared. Should it be static?
of_device_common.c:24:5: warning: symbol 'of_address_to_resource' was not declared. Should it be static?
of_device_common.c:37:14: warning: symbol 'of_iomap' was not declared. Should it be static?

Add missing includes.

sparc: delete non-required instances of include

2014-01-29T07:38:23+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

sparc: move symbol exporters to use export.h not module.h

2011-10-31T23:30:53+00:00

Many of the core sparc kernel files are not modules, but just
including module.h for exporting symbols.  Now these files can
use the lighter footprint export.h for this role.

sparc: Implement of_address_to_resource().

Similarly to irq_of_parse_and_map(), find the platform_device
object and return the pre-computed resource.
