2015-02-05xen/arm/arm64: introduce xen_arch_need_swiotlbStefano Stabellini
commit a4dba130891271084344c12537731542ec77cb85 upstream. Introduce an arch specific function to find out whether a particular dma mapping operation needs to bounce on the swiotlb buffer. On ARM and ARM64, if the page involved is a foreign page and the device is not coherent, we need to bounce because at unmap time we cannot execute any required cache maintenance operations (we don't know how to find the pfn from the mfn). No change of behaviour for x86.

2015-02-05ARM: mvebu: don't set the PL310 in I/O coherency mode when I/O coherency is ↵Thomas Petazzoni
disabled commit dcad68876c21bac709b01eda24e39d4410dc36a8 upstream. Since commit f2c3c67f00 (merge commit that adds commit "ARM: mvebu: completely disable hardware I/O coherency"), we disable I/O coherency on Armada EBU platforms. However, we continue to initialize the coherency fabric, because this coherency fabric is needed on Armada XP for inter-CPU coherency. Unfortunately, due to this, we also continued to execute the coherency fabric initialization code for Armada 375/38x, which switched the PL310 into I/O coherent mode. This has the effect of disabling the outer cache sync operation: this is needed when I/O coherency is enabled to work around a PCIe/L2 deadlock. But obviously, when I/O coherency is disabled, having the outer cache sync operation is crucial. Therefore, this commit fixes the armada_375_380_coherency_init() so that the PL310 is switched to I/O coherent mode only if I/O coherency is enabled. Without this fix, all devices using DMA are broken on Armada 375/38x.

2015-01-29ARM: mvebu: completely disable hardware I/O coherencyThomas Petazzoni
commit 8f1e8ee28660018a935c7576b9af8ffe1feab54c upstream. The current hardware I/O coherency is known to cause problems with DMA coherent buffers, as it still requires explicit I/O synchronization barriers, which is not compatible with the semantics expected by the Linux DMA coherent buffers API. So, in order to have enough time to validate a new solution based on automatic I/O synchronization barriers, this commit disables hardware I/O coherency entirely. Future patches will re-enable it.

commit 7ecd0bde5bfea524a843ad8fa8cb66ccbce68779 upstream. Currently PWM functionality is broken on mx25 due to the wrong assignment of the PWM "per" clock. According to Documentation/devicetree/bindings/clock/imx25-clock.txt: pwm_ipg_per 52 ,so update the pwm "per" to use 'pwm_ipg_per' instead of 'per10' clock.

2015-01-27ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instancesGeert Uytterhoeven
commit b0ddb319db3d7a1943445f0de0a45c07a7f3457a upstream. The sh73a0 INTC can't mask interrupts properly most likely due to a hardware bug. Set the .control_parent flag to delegate masking to the parent interrupt controller, like was already done for irqpin1. Without this, accessing the three-axis digital accelerometer ADXL345 on kzm9g through /dev/input/event1 causes an interrupt storm, which requires a power-cycle to recover from.

2015-01-27ARM: omap5/dra7xx: Enable booting secondary CPU in HYP modeLennart Sorensen
commit 999f934de195a1506089b52c77429fdba25da688 upstream. If the boot loader enables HYP mode on the boot CPU, the secondary CPU also needs to call into the ROM to switch to HYP mode before booting. The firmwares on the omap5 and dra7xx unfortunately do not take care of this, so it has to be handled by the kernel. This patch is based on "[PATCH 2/2] ARM: OMAP5: Add HYP mode entry support for secondary CPUs" by Santosh Shilimkar <santosh.shilimkar@ti.com>, except this version does not require a compile time CONFIG to control if it should enable HYP mode or not, it simply does it based on the mode of the boot CPU, so it works whether the CPU boots in SVC or HYP mode, and should even work as a guest kernel inside kvm if qemu decides to support emulating the omap5 or dra7xx.

2015-01-27ARM: dts: imx51-babbage: Fix ULPI PHY reset modellingFabio Estevam
commit 7a9f0604bd56936b2b18f49824e0e392dc7878c3 upstream. GPIO2_5 is the reset GPIO for the USB3317 ULPI PHY. Instead of modelling it as a regulator, the correct approach is to use the 'reset_gpios' property of the "usb-nop-xceiv" node. GPIO1_7 is the reset GPIO for the USB2517 USB hub. As we currently don't have dt bindings to describe a HUB reset, let's keep using the regulator approach. Rename the regulator to 'reg_hub_reset' to better describe its function and bind it with the USB host1 port instead. USB host support has been introduced by commit 9bf206a9d13be3 ("ARM: dts: imx51-babbage: Add USB Host1 support"), which landed in 3.16 and it seems that USB has only been functional due to previous bootloader initialization. With this patch applied we can get USB host to work without relying on the bootloader.

2015-01-08ARM: mvebu: remove conflicting muxing on Armada 370 DBThomas Petazzoni
commit b4607572ef86b288a856b9df410ea593c5371dec upstream. Back when audio was enabled, the muxing of some MPP pins was causing problems. However, since commit fea038ed55ae ("ARM: mvebu: Add proper pin muxing on the Armada 370 DB board"), those problematic MPP pins have been assigned a proper muxing for the Ethernet interfaces. This proper muxing is now conflicting with the hog pins muxing that had been added as part of 249f3822509b ("ARM: mvebu: add audio support to Armada 370 DB"). Therefore, this commit simply removes the hog pins muxing, which solves a warning a boot time due to the conflicting muxing requirements.

2015-01-08ARM: mvebu: disable I/O coherency on non-SMP situations on Armada 370/375/38x/XPThomas Petazzoni
commit e55355453600a33bb5ca4f71f2d7214875f3b061 upstream. Enabling the hardware I/O coherency on Armada 370, Armada 375, Armada 38x and Armada XP requires a certain number of conditions: - On Armada 370, the cache policy must be set to write-allocate. - On Armada 375, 38x and XP, the cache policy must be set to write-allocate, the pages must be mapped with the shareable attribute, and the SMP bit must be set Currently, on Armada XP, when CONFIG_SMP is enabled, those conditions are met. However, when Armada XP is used in a !CONFIG_SMP kernel, none of these conditions are met. With Armada 370, the situation is worse: since the processor is single core, regardless of whether CONFIG_SMP or !CONFIG_SMP is used, the cache policy will be set to write-back by the kernel and not write-allocate. Since solving this problem turns out to be quite complicated, and we don't want to let users with a mainline kernel known to have infrequent but existing data corruptions, this commit proposes to simply disable hardware I/O coherency in situations where it is known not to work. And basically, the is_smp() function of the kernel tells us whether it is OK to enable hardware I/O coherency or not, so this commit slightly refactors the coherency_type() function to return COHERENCY_FABRIC_TYPE_NONE when is_smp() is false, or the appropriate type of the coherency fabric in the other case. Thanks to this, the I/O coherency fabric will no longer be used at all in !CONFIG_SMP configurations. It will continue to be used in CONFIG_SMP configurations on Armada XP, Armada 375 and Armada 38x (which are multiple cores processors), but will no longer be used on Armada 370 (which is a single core processor). In the process, it simplifies the implementation of the coherency_type() function, and adds a missing call to of_node_put().

2015-01-08ARM: mvebu: make the coherency_ll.S functions work with no coherency fabricThomas Petazzoni
commit 30cdef97107370a7f63ab5d80fd2de30540750c8 upstream. The ll_add_cpu_to_smp_group(), ll_enable_coherency() and ll_disable_coherency() are used on Armada XP to control the coherency fabric. However, they make the assumption that the coherency fabric is always available, which is currently a correct assumption but will no longer be true with a followup commit that disables the usage of the coherency fabric when the conditions are not met to use it. Therefore, this commit modifies those functions so that they check the return value of ll_get_coherency_base(), and if the return value is 0, they simply return without configuring anything in the coherency fabric. The ll_get_coherency_base() function is also modified to properly return 0 when the function is called with the MMU disabled. In this case, it normally returns the physical address of the coherency fabric, but we now check if the virtual address is 0, and if that's case, return a physical address of 0 to indicate that the coherency fabric is not enabled.

2015-01-08ARM: tegra: Re-add removed SoC id macro to tegra_resume()Dmitry Osipenko
commit e4a680099a6e97ecdbb81081cff9e4a489a4dc44 upstream. Commit d127e9c ("ARM: tegra: make tegra_resume can work with current and later chips") removed tegra_get_soc_id macro leaving used cpu register corrupted after branching to v7_invalidate_l1() and as result causing execution of unintended code on tegra20. Possibly it was expected that r6 would be SoC id func argument since common cpu reset handler is setting r6 before branching to tegra_resume(), but neither tegra20_lp1_reset() nor tegra30_lp1_reset() aren't setting r6 register before jumping to resume function. Fix it by re-adding macro.

2015-01-08clocksource: arch_timer: Fix code to use physical timers when requestedSonny Rao
commit 0b46b8a718c6e90910a1b1b0fe797be3c167e186 upstream. This is a bug fix for using physical arch timers when the arch_timer_use_virtual boolean is false. It restores the arch_counter_get_cntpct() function after removal in 0d651e4e "clocksource: arch_timer: use virtual counters" We need this on certain ARMv7 systems which are architected like this: * The firmware doesn't know and doesn't care about hypervisor mode and we don't want to add the complexity of hypervisor there. * The firmware isn't involved in SMP bringup or resume. * The ARCH timer come up with an uninitialized offset between the virtual and physical counters. Each core gets a different random offset. * The device boots in "Secure SVC" mode. * Nothing has touched the reset value of CNTHCTL.PL1PCEN or CNTHCTL.PL1PCTEN (both default to 1 at reset) One example of such as system is RK3288 where it is much simpler to use the physical counter since there's nobody managing the offset and each time a core goes down and comes back up it will get reinitialized to some other random value.

We cannot restart cacheflush safely if a process provides user-defined signal handler and signal is pending. In this case -EINTR is returned and it is expected that process re-invokes syscall. However, there are a few problems with that: * looks like nobody bothers checking return value from cacheflush * but if it did, we don't provide the restart address for that, so the process has to use the same range again * ...and again, what might lead to looping forever So, remove cacheflush restarting code and terminate cache flushing as early as fatal signal is pending.

2014-11-27ARM: 8222/1: mvebu: enable strex backoff delayThomas Petazzoni
Under extremely rare conditions, in an MPCore node consisting of at least 3 CPUs, two CPUs trying to perform a STREX to data on the same shared cache line can enter a livelock situation. This patch enables the HW mechanism that overcomes the bug. This fixes the incorrect setup of the STREX backoff delay bit due to a wrong description in the specification. Note that enabling the STREX backoff delay mechanism is done by leaving the bit *cleared*, while the bit was currently being set by the proc-v7.S code.

2014-11-27ARM: tegra: irq: fix buggy usage of irq_data irq fieldMarc Zyngier
The crazy gic_arch_extn thing that Tegra uses contains multiple references to the irq field in struct irq_data, and uses this to directly poke hardware register. But irq is the *virtual* irq number, something that has nothing to do with the actual HW irq (stored in the hwirq field). And once we put the stacked domain code in action, the whole thing explodes, as these two values are *very* different: root@bacon-fat:~# cat /proc/interrupts CPU0 CPU1 16: 25801 2075 GIC 29 twd 17: 0 0 GIC 73 timer0 112: 0 0 GPIO 58 c8000600.sdhci cd 123: 0 0 GPIO 69 c8000200.sdhci cd 279: 1126 0 GIC 122 serial 281: 0 0 GIC 70 7000c000.i2c 282: 0 0 GIC 116 7000c400.i2c 283: 0 0 GIC 124 7000c500.i2c 284: 300 0 GIC 85 7000d000.i2c [...] Just replacing all instances of irq with hwirq fixes the issue.

2014-11-26arm64: KVM: fix unmapping with 48-bit VAsMark Rutland
Currently if using a 48-bit VA, tearing down the hyp page tables (which can happen in the absence of a GICH or GICV resource) results in the rather nasty splat below, evidently becasue we access a table that doesn't actually exist. Commit 38f791a4e499792e (arm64: KVM: Implement 48 VA support for KVM EL2 and Stage-2) added a pgd_none check to __create_hyp_mappings to account for the additional level of tables, but didn't add a corresponding check to unmap_range, and this seems to be the source of the problem. This patch adds the missing pgd_none check, ensuring we don't try to access tables that don't exist.

2014-11-21ARM: 8216/1: xscale: correct auxiliary register in suspend/resumeDmitry Eremin-Solenikov
According to the manuals I have, XScale auxiliary register should be reached with opc_2 = 1 instead of crn = 1. cpu_xscale_proc_init correctly uses c1, c0, 1 arguments, but cpu_xscale_do_suspend and cpu_xscale_do_resume use c1, c1, 0. Correct suspend/resume functions to also use c1, c0, 1. The issue was primarily noticed thanks to qemu reporing "unsupported instruction" on the pxa suspend path. Confirmed in PXA210/250 and PXA255 XScale Core manuals and in PXA270 and PXA320 Developers Guides. Harware tested by me on tosa (pxa255). Robert confirmed on pxa270 board.

Commit 6e80e3d87549 ("ARM: exynos_defconfig: Enable MAX77802") enabled support for the max77802 regulators but the PMIC also has a Real-Time-Clock (RTC) and 2-channel 32kHz clock outputs. Enable the kernel config options to have the drivers for these devices built-in since they are present in many Exynos boards.

2014-11-19ARM: multi_v7_defconfig: fix failure setting CPU voltage by enabling ↵Tyler Baker
dependent I2C controller This patch fixes a long standing issue introduced during the 3.16 merge window. Shortly after the merge, exynos5250-based arndale boards began to produce the following errors: kern.err kernel: exynos-cpufreq exynos-cpufreq: failed to set cpu voltage kern.err kernel: cpufreq: __target_index: Failed to change cpu frequency: -22 Further analysis revealed that the S5M8767 voltage regulator used on the exynos5250-based arndale board utilizes the S3C2410 I2C controller. If the S3C2410 I2C controller driver is not enabled, the S5M8767 voltage regulator fails to probe. Therefore a dependency exists between these two drivers. In the exynos_defconfig both CONFIG_REGULATOR_S5M8767 and CONFIG_I2C_S3C2410 options are enabled, and no errors are produced. However, in the multi_v7_defconfig only the CONFIG_REGULATOR_S5M8767 option is enabled and the errors are present. So let's enable the CONFIG_I2C_S3C2410 option in the multi_v7_defconfig to allow the S5M8767 voltage regulator to probe.
