git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc updates from Ben Herrenschmidt: "So here's my next branch for powerpc. A bit late as I was on vacation last week. It's mostly the same stuff that was in next already, I just added two patches today which are the wiring up of lockref for powerpc, which for some reason fell through the cracks last time and is trivial. The highlights are, in addition to a bunch of bug fixes: - Reworked Machine Check handling on kernels running without a hypervisor (or acting as a hypervisor). Provides hooks to handle some errors in real mode such as TLB errors, handle SLB errors, etc... - Support for retrieving memory error information from the service processor on IBM servers running without a hypervisor and routing them to the memory poison infrastructure. - _PAGE_NUMA support on server processors - 32-bit BookE relocatable kernel support - FSL e6500 hardware tablewalk support - A bunch of new/revived board support - FSL e6500 deeper idle states and altivec powerdown support You'll notice a generic mm change here, it has been acked by the relevant authorities and is a pre-req for our _PAGE_NUMA support" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (121 commits) powerpc: Implement arch_spin_is_locked() using arch_spin_value_unlocked() powerpc: Add support for the optimised lockref implementation powerpc/powernv: Call OPAL sync before kexec'ing powerpc/eeh: Escalate error on non-existing PE powerpc/eeh: Handle multiple EEH errors powerpc: Fix transactional FP/VMX/VSX unavailable handlers powerpc: Don't corrupt transactional state when using FP/VMX in kernel powerpc: Reclaim two unused thread_info flag bits powerpc: Fix races with irq_work Move precessing of MCE queued event out from syscall exit path. pseries/cpuidle: Remove redundant call to ppc64_runlatch_off() in cpu idle routines powerpc: Make add_system_ram_resources() __init powerpc: add SATA_MV to ppc64_defconfig powerpc/powernv: Increase candidate fw image size powerpc: Add debug checks to catch invalid cpu-to-node mappings powerpc: Fix the setup of CPU-to-Node mappings during CPU online powerpc/iommu: Don't detach device without IOMMU group powerpc/eeh: Hotplug improvement powerpc/eeh: Call opal_pci_reinit() on powernv for restoring config space powerpc/eeh: Add restore_config operation ...
2014-01-16dt/bindings: Remove device_type "serial" from marvell,mv64360-mpscGrant Likely2-4/+0
device_type is deprecated. There is no need to check for it in device driver code and no need to specify it in the device tree. Remove the property from stock .dts files and remove the check for it from device drivers. This change should be 100% backwards compatible with old device trees.

2014-01-16dt/bindings: remove users of device_type "mdio"Grant Likely6-6/+0
device_type is a deprecated property, but some MDIO bus nodes still have it. Except for a couple of old binding (compatible="gianfar" and compatible="ucc_geth_phy") the kernel doesn't look for device_type="mdio" at all. This patch removes all instances of device_type="mdio" from the binding documentation and the .dts files.

2014-01-16dt/bindings: Remove all references to device_type "ethernet-phy"Grant Likely59-145/+0
The device_type property is deprecated for the flattened device tree and the value "ethernet-phy" has never been defined as having a useful meaning. Neither the kernel nor u-boot depend on it. It should never have appeared in PHY bindings. This patch removes all references to "ethernet-phy" as a device_type value from the documentation and the .dts files. This patch was generated mechanically with the following command and then verified by looking at the diff. sed -i '/"ethernet-phy"/d' `git grep -l '"ethernet-phy"'` Signed-off-by: Grant Likely <grant.likely@linaro.org> Acked-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: Kumar Gala <galak@codeaurora.org> Cc: Florian Fainelli <f.fainelli@gmail.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org>

this addresses the clock driver aka provider's side of clocks - introduce a 'clocks' subtree with an 'osc' node for the crystal or oscillator SoC input (fixed frequency) - the 'clock@f00' clock-control-module node references the 'osc' for its input, and is another provider for all the clocks which the CCM component manages - prepare for future references to clocks from peripheral nodes by means of the <&clks ID> syntax and symbolic ID names which a header file provides - provide default values with 33MHz oscillator frequency in the common include (the 66MHz IPS bus already was there), and add override values for the ifm AC14xx board which deviates from the reference design (25MHz xtal, 80MHz IPS bus) Cc: Rob Herring <rob.herring@calxeda.com> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Stephen Warren <swarren@wwwdotorg.org> Cc: Ian Campbell <ian.campbell@citrix.com> Cc: linux-arm-kernel@lists.infradead.org Cc: devicetree@vger.kernel.org Reviewed-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>
2014-01-10powerpc/85xx/dts: add third elo3 dma componentShengzhou Liu1-0/+82
Add elo3-dma-2.dtsi to support the third DMA controller. This is used on T2080, T4240, B4860, etc. FSL MPIC v4.3 adds a new discontiguous address range for internal interrupts, e.g. internal interrupt 0 is at offset 0x200 and thus interrupt number is: 0x200 >> 5 = 16 in the device tree. DMA controller 3 channel 0 internal interrupt 240 is at offset 0x3a00, and thus the corresponding interrupt number is: 0x3a00 >> 5 = 464, it's similar for other 7 interrupt numbers of DMA 3 channels.

Add support for the Motorola/Emerson MVME5100 Single Board Computer. The MVME5100 is a 6U form factor VME64 computer with: - A single MPC7410 or MPC750 CPU - A HAWK Processor Host Bridge (CPU to PCI) and MultiProcessor Interrupt Controller (MPIC) - Up to 500Mb of onboard memory - A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip - Two 16550 compatible UARTS - Two Intel E100 Fast Ethernets - Two PCI Mezzanine Card (PMC) Slots - PPCBug Firmware The HAWK PHB/MPIC is compatible with the MPC10x devices. There is no onboard disk support. This is usually provided by installing a PMC in first PMC slot. This patch revives the board support, it was present in early 2.6 series kernels. The board support in those days was by Matt Porter of MontaVista Software. CSC Australia has around 31 of these boards in service. The kernel in use for the boards is based on 2.6.31. The boards are operated without disks from a file server. This patch is based on linux-3.13-rc2 and has been boot tested. Only boards with 512 Mb of memory are known to work.

2013-11-05powerpc/boot: Properly handle the base "of" boot wrapperBenjamin Herrenschmidt1-0/+4
The wrapper script needs an explicit rule for the "of" boot wrapper (generic wrapper, similar to pseries). Before 0c9fa29149d3726e14262aeb0c8461a948cc9d56 it was hanlded implicitly by the statement: platformo=$object/"$platform".o But now that epapr.o needs to be added, that doesn't work and an explicit rule must be added.

2013-10-30powerpc/boot: Don't change link address for OF-based platformsPaul Mackerras1-0/+4
Commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the wrapper to fit the kernel") adjusts the wrapper address unnecessarily for platforms that use arch/powerpc/boot/of.c, since the code there allocates space for the kernel wherever it can find it and doesn't necessarily load the kernel at address 0. Changing the link address is actually harmful since it can cause the zImage to overlap with Open Firmware and thus fail to boot. To fix this, we set make_space to n for all of the platforms that use of.o. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2013-08-20powerpc: Convert some mftb/mftbu into mfsprScott Wood2-5/+8
Some CPUs (such as e500v1/v2) don't implement mftb and will take a trap. mfspr should work on everything that has a timebase, and is the preferred instruction according to ISA v2.06. Currently we get away with mftb on 85xx because the assembler converts it to mfspr due to -Wa,-me500. However, that flag has other effects that are undesireable for certain targets (e.g. lwsync is converted to sync), and is hostile to multiplatform kernels. Thus we would like to stop setting it for all e500-family builds. mftb/mftbu instances which are in 85xx code or common code are converted. Instances which will never run on 85xx are left alone.
