2010-06-28of: kill struct of_deviceGrant Likely2-16/+2
Now that the device tree node pointer has been moved out of struct of_device and into the common struct device, there isn't anything unique about of_device anymore. In fact, there isn't much need for a separate of_bus when all busses have access to OF style probing. arch/powerpc and arch/microblaze are moving away from using the of_bus and using the regular platform bus instead for mmio devices. This patch makes of_device the same as platform_device as a stepping stone in migrating of_platform_drivers over to the platform bus.

2010-06-28sparc/of: Move of_device fields into struct pdev_archdataGrant Likely12-64/+56
This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: Grant Likely <[email protected]> Acked-by: David S.

2010-05-27asm-generic: remove ISA_DMA_THRESHOLD in scatterlist.hFUJITA Tomonori1-0/+2
This is the first half of the attempt to use asm-generic/scatterlist.h on every architecture. There are only two ways to define scatterlist structure. So it's easy to convert every architecture to use asm-generic/scatterlist.h. This patch: The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work for powerpc.

For some reason, the pte_none() calculation for srmmu sparc32 chips was masking out the top 4 bits. That doesn't make any sense, as those are just some of the physical bits of the PTE encoding. Furthermore, this mistake breaks things when the offset of of a swap entry has a large enough offset as reported by Тхай Кирилл.

2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund2-12/+0
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial.

2010-04-28driver-core: Add device node pointer to struct deviceGrant Likely3-0/+3
Currently, platforms using CONFIG_OF add a 'struct device_node *of_node' to dev->archdata. However, with CONFIG_OF becoming generic for all architectures, it makes sense for commonality to move it out of archdata and into struct device proper. This patch adds a struct device_node *of_node member to struct device and updates all locations which currently write the device_node pointer into archdata to also update dev->of_node. Subsequent patches will modify callers to use the archdata location and ultimately remove the archdata member entirely.
