With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices. Signed-off-by: Magnus Damm --- Applies to next-20090610. Changes since V2: - updated commit message, thanks to Rafael for feedback Changes since V1: - post to lkml, keep linux-pm cc:ed - add struct pdev_archdata to asm-generic - add struct pdev_archdata to non-generic architectures - drop Kconfig bits arch/arm/include/asm/device.h | 3 +++ arch/ia64/include/asm/device.h | 3 +++ arch/microblaze/include/asm/device.h | 3 +++ arch/powerpc/include/asm/device.h | 3 +++ arch/sparc/include/asm/device.h | 3 +++ arch/x86/include/asm/device.h | 3 +++ include/asm-generic/device.h | 3 +++ include/linux/platform_device.h | 3 +++ 8 files changed, 24 insertions(+) --- 0001/arch/arm/include/asm/device.h +++ work/arch/arm/include/asm/device.h 2009-06-01 12:19:51.000000000 +0900 @@ -12,4 +12,7 @@ struct dev_archdata { #endif }; +struct pdev_archdata { +}; + #endif --- 0001/arch/ia64/include/asm/device.h +++ work/arch/ia64/include/asm/device.h 2009-06-01 12:18:11.000000000 +0900 @@ -15,4 +15,7 @@ struct dev_archdata { #endif }; +struct pdev_archdata { +}; + #endif /* _ASM_IA64_DEVICE_H */ --- 0001/arch/microblaze/include/asm/device.h +++ work/arch/microblaze/include/asm/device.h 2009-06-01 12:19:32.000000000 +0900 @@ -16,6 +16,9 @@ struct dev_archdata { struct device_node *of_node; }; +struct pdev_archdata { +}; + #endif /* _ASM_MICROBLAZE_DEVICE_H */ --- 0001/arch/powerpc/include/asm/device.h +++ work/arch/powerpc/include/asm/device.h 2009-06-01 12:16:28.000000000 +0900 @@ -30,4 +30,7 @@ dev_archdata_get_node(const struct dev_a return ad->of_node; } +struct pdev_archdata { +}; + #endif /* _ASM_POWERPC_DEVICE_H */ --- 0001/arch/sparc/include/asm/device.h +++ work/arch/sparc/include/asm/device.h 2009-06-01 12:18:57.000000000 +0900 @@ -32,4 +32,7 @@ dev_archdata_get_node(const struct dev_a return ad->prom_node; } +struct pdev_archdata { +}; + #endif /* _ASM_SPARC_DEVICE_H */ --- 0001/arch/x86/include/asm/device.h +++ work/arch/x86/include/asm/device.h 2009-06-01 12:17:28.000000000 +0900 @@ -13,4 +13,7 @@ struct dma_map_ops *dma_ops; #endif }; +struct pdev_archdata { +}; + #endif /* _ASM_X86_DEVICE_H */ --- 0001/include/asm-generic/device.h +++ work/include/asm-generic/device.h 2009-06-01 12:16:20.000000000 +0900 @@ -9,4 +9,7 @@ struct dev_archdata { }; +struct pdev_archdata { +}; + #endif /* _ASM_GENERIC_DEVICE_H */ --- 0001/include/linux/platform_device.h +++ work/include/linux/platform_device.h 2009-06-01 12:14:43.000000000 +0900 @@ -22,6 +22,9 @@ struct platform_device { struct resource * resource; struct platform_device_id *id_entry; + + /* arch specific additions */ + struct pdev_archdata archdata; }; #define platform_get_device_id(pdev) ((pdev)->id_entry) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
