2014-06-26ARM: at91: fix at91_sysirq_mask_rtc for sam9x5 SoCsBoris BREZILLON
commit 9dcc87fec8947308e0111c65dcd881e6aa5b1673 upstream. sam9x5 SoCs have the following errata: "RTC: Interrupt Mask Register cannot be used Interrupt Mask Register read always returns 0." Hence we should not rely on what IMR claims about already masked IRQs and just disable all IRQs.

2014-05-28ARM: 8063/1: bL_switcher: fix individual online status reporting of removed CPUsNicolas Pitre
The content of /sys/devices/system/cpu/cpu*/online is still 1 for those CPUs that the switcher has removed even though the global state in /sys/devices/system/cpu/online is updated correctly. It turns out that commit 0902a9044f ("Driver core: Use generic offline/online for CPU offline/online") has changed the way those files retrieve their content by relying on on the generic attribute handling code. The switcher, by calling cpu_down() directly, bypasses this handling and the attribute value doesn't get updated. Fix this by calling device_offline()/device_online() instead.

2014-05-25ARM: 8064/1: fix v7-M signal returnRabin Vincent
According to the ARM ARM, the behaviour is UNPREDICTABLE if the PC read from the exception return stack is not half word aligned. See the pseudo code for ExceptionReturn() and PopStack(). The signal handler's address has the bit 0 set, and setup_return() directly writes this to regs->ARM_pc. Current hardware happens to discard this bit, but QEMU's emulation doesn't and this makes processes crash. Mask out bit 0 before the exception return in order to get predictable behaviour.

2014-05-25ARM: 8052/1: unwind: Fix handling of "Pop r4-r[4+nnn],r14" opcodeNikolay Borisov
The arm EABI states that unwind opcode 10100nnn means pop register r4-4[4+nnn],aditionally there is a similar unwind opcode: 10101nnn which means the same thing plus popping r14. Those two cases are handled by the unwind_exec_pop_r4_to_rN function which checks whether the 4th bit is set and does r14 popping. However, up until now it has been checking whether the 8th bit was set (mask & 0x80) instead of the 4th (mask & 0x8), a simple to make typo but this meant that we were always popping r14 even if we had the former opcode. This patch changes the mask so that the 2 unwind opcodes are being handled correctly.

2014-05-19ARM: OMAP4: Fix the boot regression with CPU_IDLE enabledSantosh Shilimkar
On OMAP4 panda board, there have been several bug reports about boot hang and lock-ups with CPU_IDLE enabled. The root cause of the issue is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common code for right reasons but on OMAP4 which suffers from a nasty ROM code bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..}, we loose interrupts which leads to issues like lock-up, hangs etc. Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to avoid the issue. With this change, OMAP4 panda boards, the mentioned issues are getting fixed. We no longer loose interrupts which was the cause of the regression.

2014-05-16ARM: OMAP2+: Fix DMA hang after off-idleTony Lindgren
Commit 6ddeb6d84459 (dmaengine: omap-dma: move IRQ handling to omap-dma) added support for handling interrupts in the omap dmaengine driver instead of the legacy driver. Because of different handling for interrupts this however caused omap3 to hang eventually after hitting off-idle. Any of the virtual 32 DMA channels can be assigned to any of the four DMA interrupts. So commit 6ddeb6d84459 made the omap dmaengine driver to use the second DMA interrupt while keeping the legacy code still using the first DMA interrupt. This means we need to save and restore both IRQENABLE_L1 in addition to IRQENABLE_L0. As there is a chance that the DSP might be using IRQENABLE_L2 or IRQENABLE_L3 lines, let's not touch those until this has been confirmed. Let's just add a comment to the code for now.

2014-05-13ARM: mvebu: mvebu-soc-id: keep clock enabled if PCIe unit is enabledThomas Petazzoni
Since the mvebu-soc-id code in mach-mvebu/ was introduced, several users have noticed a regression: the PCIe card connected in the first PCIe interface is not detected properly. This is due to the fact that the mvebu-soc-id code enables the PCIe clock of the first PCIe interface, reads the SoC device ID and revision number (yes this information is made available as part of PCIe registers), and then disables the clock. However, by doing this, we gate the clock and therefore loose the complex PCIe configuration that was done by the bootloader. Unfortunately, as of today, the kernel is not capable of doing this complex configuration by itself, so we really need to keep the PCIe clock enabled. However, we don't want to keep it enabled unconditionally: if the PCIe interface is not enabled or PCI support is not compiled into the kernel, there is no reason to keep the PCIe clock running. This issue was discussed with Kevin Hilman, and the suggested solution was to make the mvebu-soc-id code keep the clock enabled in case it will be needed for PCIe. This is therefore the solution implemented in this patch. Long term, we hope to make the kernel more capable in terms of PCIe configuration for this platform, which will anyway be needed to support the compilation of the PCIe host controller driver as a module. In the mean time however, we don't have much other choice than to implement the currently proposed solution.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "Seems like we've had more fixes than usual this release cycle, but there's nothing in particular that we're doing differently. Perhaps it's just one of those cycles where more people are finding more regressions (and/or that the latency of when people actually test what's been in the tree for a while is catching up so that we get the bug reports now). The bigger changes here are are for TI and Marvell platforms: * Timing changes for GPMC (generic localbus) on OMAP causing some largeish DTS deltas. * Fixes to window allocation on PCI for mvebu touching drivers/ stuff. Patches have acks from subsystem maintainers where needed. * A fix from Thomas for a botched DT conversion in drivers/edma. There's a handful of other fixes for the above platforms as well as sunxi, at91, i.MX. I also included a MAINTAINER update for Broadcom, and a trivial move of a binding doc.

2014-05-05ARM: dts: kirkwood: fix mislocated pcie-controller nodesSebastian Hesselbarth
Commit 54397d85349f ("ARM: kirkwood: Relocate PCIe device tree nodes") moved the pcie-controller nodes for the Kirkwood SoCs to the mbus bus node. For some reason, two boards were not properly converted and have their pci-controller nodes still in the ocp bus node. As the corresponding SoC pcie-controller does not exist anymore, it is likely that pcie is broken on those boards since above commit. Fix it by moving the pcie related nodes to the correct location.

2014-04-29ARM: common: edma: Fix xbar mappingThomas Gleixner
This is another great example of trainwreck engineering: commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support) added support for using EDMA on peripherals which have no direct EDMA event mapping. The code compiles and does not explode in your face, but that's it. 1) Reading an u16 array from an u32 device tree array simply does not work. Even if the function is named "edma_of_read_u32_to_s16_array". It merily calls of_property_read_u16_array. So the resulting 16bit array will have every other entry = 0. 2) The DT entry for the xbar registers related to xbar has length 0x10 instead of the real length: 0xfd0 - 0xf90 = 0x40. Not a real problem as it does not cross a page boundary, but wrong nevertheless. 3) But none of this matters as the mapping never happens: After reading nonsense edma_of_read_u32_to_s16_array() invalidates the first array entry pair, so nobody can ever notice the braindamage by immediate explosion. Seems the QA criteria for this code was solely not to explode when someone adds edma-xbar-event-map entries to the DT. Goal achieved, congratulations! Not really helpful if someone wants to use edma on a device which requires a xbar mapping. Fix the issues by: - annotating the device tree entry with "/bits/ 16" as documented in the of_property_read_u16_array kernel doc - make the size of the xbar register mapping correct - invalidating the end of the array and not the start This convoluted mess wants to be completely rewritten as there is no point to keep the xbar_chan array memory and the iomapping of the xbar regs around forever. Marking the xbar mapped channels as used should be done right there. But that's a different issue and this patch is small enough to make it work and allows a simple backport for stable.
