Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
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..." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (73 commits) powerpc+of: Rename and fix OF reconfig notifier error inject module powerpc: mpc5200: Add a3m071 board support powerpc/512x: don't compile any platform DIU code if the DIU is not enabled powerpc/mpc52xx: use module_platform_driver macro powerpc+of: Export of_reconfig_notifier_[register,unregister] powerpc/dma/raidengine: add raidengine device powerpc/iommu/fsl: Add PAMU bypass enable register to ccsr_guts struct powerpc/mpc85xx: Change spin table to cached memory powerpc/fsl-pci: Add PCI controller ATMU PM support powerpc/86xx: fsl_pcibios_fixup_bus requires CONFIG_PCI drivers/virt: the Freescale hypervisor driver doesn't need to check MSR[GS] powerpc/85xx: p1022ds: Use NULL instead of 0 for pointers powerpc: Disable relocation on exceptions when kexecing powerpc: Enable relocation on during exceptions at boot powerpc: Move get_longbusy_msecs into hvcall.h and remove duplicate function powerpc: Add wrappers to enable/disable relocation on exceptions powerpc: Add set_mode hcall powerpc: Setup relocation on exceptions for bare metal systems powerpc: Move initial mfspr LPCR out of __init_LPCR powerpc: Add relocation on exception vector handlers ...

1* Freescale 85xx RAID Engine nodes
2
3RAID Engine nodes are defined to describe on-chip RAID accelerators. Each RAID
4Engine should have a separate node.
5
6Supported chips:
7P5020, P5040
8
9Required properties:
10
11- compatible: Should contain "fsl,raideng-v1.0" as the value
12 This identifies RAID Engine block. 1 in 1.0 represents
13 major number whereas 0 represents minor number. The
14 version matches the hardware IP version.
15- reg: offset and length of the register set for the device
16- ranges: standard ranges property specifying the translation
17 between child address space and parent address space
18
19Example:
20 /* P5020 */
21 raideng: raideng@320000 {
22 compatible = "fsl,raideng-v1.0";
23 #address-cells = <1>;
24 #size-cells = <1>;
25 reg = <0x320000 0x10000>;
26 ranges = <0 0x320000 0x10000>;
27 };
28
29
30There must be a sub-node for each job queue present in RAID Engine
31This node must be a sub-node of the main RAID Engine node
32
33- compatible: Should contain "fsl,raideng-v1.0-job-queue" as the value
34 This identifies the job queue interface
35- reg: offset and length of the register set for job queue
36- ranges: standard ranges property specifying the translation
37 between child address space and parent address space
38
39Example:
40 /* P5020 */
41 raideng_jq0@1000 {
42 compatible = "fsl,raideng-v1.0-job-queue";
43 reg = <0x1000 0x1000>;
44 ranges = <0x0 0x1000 0x1000>;
45 };
46
47
48There must be a sub-node for each job ring present in RAID Engine
49This node must be a sub-node of job queue node
50
51- compatible: Must contain "fsl,raideng-v1.0-job-ring" as the value
52 This identifies job ring. Should contain either
53 "fsl,raideng-v1.0-hp-ring" or "fsl,raideng-v1.0-lp-ring"
54 depending upon whether ring has high or low priority
55- reg: offset and length of the register set for job ring
56- interrupts: interrupt mapping for job ring IRQ
57
58Optional property:
59
60- fsl,liodn: Specifies the LIODN to be used for Job Ring. This
61 property is normally set by firmware. Value
62 is of 12-bits which is the LIODN number for this JR.
63 This property is used by the IOMMU (PAMU) to distinquish
64 transactions from this JR and than be able to do address
65 translation & protection accordingly.
66
67Example:
68 /* P5020 */
69 raideng_jq0@1000 {
70 compatible = "fsl,raideng-v1.0-job-queue";
71 reg = <0x1000 0x1000>;
72 ranges = <0x0 0x1000 0x1000>;
73
74 raideng_jr0: jr@0 {
75 compatible = "fsl,raideng-v1.0-job-ring", "fsl,raideng-v1.0-hp-ring";
76 reg = <0x0 0x400>;
77 interrupts = <139 2 0 0>;
78 interrupt-parent = <&mpic>;
79 fsl,liodn = <0x41>;
80 };
81 };
