2016-10-24usb: musb: Call pm_runtime from musb_gadget_queueTony Lindgren
If we're booting pandaboard using NFSroot over built-in g_ether, we can get the following after booting once and doing a warm reset: g_ether gadget: ecm_open g_ether gadget: notify connect true ... WARNING: CPU: 0 PID: 1 at drivers/bus/omap_l3_noc.c:147 l3_interrupt_handler+0x220/0x34c 44000000.ocp:L3 Custom Error: MASTER MPU TARGET L4CFG (Read): Data Access in User mode du ring Functional access ... Fix the issue by calling pm_runtime functions from musb_gadget_queue. Note that in the long run we should be able to queue the pending transfers if pm_runtime is not active, and flush the queue from pm_runtime_resume.

2016-10-24usb: musb: Fix hardirq-safe hardirq-unsafe lock order errorTony Lindgren
If we configure musb with 2430 glue as a peripheral, and then rmmod omap2430 module, we'll get the following error: [ INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected ] ... rmmod/413 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire: (&phy->mutex){+.+.+.}, at: [<c04b9fd0>] phy_power_off+0x1c/0xb8 [ 204.678710] and this task is already holding: (&(&musb->lock)->rlock){-.-...}, at: [<bf3a482c>] musb_gadget_stop+0x24/0xec [musb_hdrc] which would create a new lock dependency: (&(&musb->lock)->rlock){-.-...} -> (&phy->mutex){+.+.+.} ... This is because some glue layers expect musb_platform_enable/disable to be called with spinlock held, and 2430 glue layer has USB PHY on the I2C bus using a mutex. We could fix the glue layers to take the spinlock, but we still have a problem of musb_plaform_enable/disable being called in an unbalanced manner. So that would still lead into USB PHY enable/disable related problems for omap2430 glue layer. While it makes sense to only enable USB PHY when needed from PM point of view, in this case we just can't do it yet without breaking things. So let's just revert phy_enable/disable related changes instead and reconsider this after we have fixed musb_platform_enable/disable to be balanced.

2016-10-24ACPI/PCI: pci_link: Include PIRQ_PENALTY_PCI_USING for ISA IRQsSinan Kaya
Commit 103544d86976 ("ACPI,PCI,IRQ: reduce resource requirements") replaced the addition of PIRQ_PENALTY_PCI_USING in acpi_pci_link_allocate() with an addition in acpi_irq_pci_sharing_penalty(), but f7eca374f000 ("ACPI,PCI,IRQ: separate ISA penalty calculation") removed the use of acpi_irq_pci_sharing_penalty() for ISA IRQs. Therefore, PIRQ_PENALTY_PCI_USING is missing from ISA IRQs used by interrupt links. Include that penalty by adding it in the acpi_pci_link_allocate() path.

2016-10-24ACPI/PCI: pci_link: penalize SCI correctlySinan Kaya
Ondrej reported that IRQs stopped working in v4.7 on several platforms. A typical scenario, from Ondrej's VT82C694X/694X, is: ACPI: Using PIC for interrupt routing ACPI: PCI Interrupt Link [LNKA] (IRQs 1 3 4 5 6 7 10 *11 12 14 15) ACPI: No IRQ available for PCI Interrupt Link [LNKA] 8139too 0000:00:0f.0: PCI INT A: no GSI We're using PIC routing, so acpi_irq_balance == 0, and LNKA is already active at IRQ 11. In that case, acpi_pci_link_allocate() only tries to use the active IRQ (IRQ 11) which also happens to be the SCI. We should penalize the SCI by PIRQ_PENALTY_PCI_USING, but irq_get_trigger_type(11) returns something other than IRQ_TYPE_LEVEL_LOW, so we penalize it by PIRQ_PENALTY_ISA_ALWAYS instead, which makes acpi_pci_link_allocate() assume the IRQ isn't available and give up. Add acpi_penalize_sci_irq() so platforms can tell us the SCI IRQ, trigger, and polarity directly and we don't have to depend on irq_get_trigger_type().

2016-10-24ACPI/PCI/IRQ: assign ISA IRQ directly during early boot stagesSinan Kaya
We do not want to store the SCI penalty in the acpi_isa_irq_penalty[] table because acpi_isa_irq_penalty[] only holds ISA IRQ penalties and there's no guarantee that the SCI is an ISA IRQ. We add in the SCI penalty as a special case in acpi_irq_get_penalty(). But if we called acpi_penalize_isa_irq() or acpi_irq_penalty_update() for an SCI that happened to be an ISA IRQ, they stored the SCI penalty (part of the acpi_irq_get_penalty() return value) in acpi_isa_irq_penalty[]. Subsequent calls to acpi_irq_get_penalty() returned a penalty that included *two* SCI penalties.

2016-10-24gpio: mpc8xxx: Correct irq handler functionLiu Gang
From the beginning of the gpio-mpc8xxx.c, the "handle_level_irq" has being used to handle GPIO interrupts in the PowerPC/Layerscape platforms. But actually, almost all PowerPC/Layerscape platforms assert an interrupt request upon either a high-to-low change or any change on the state of the signal. So the "handle_level_irq" is not reasonable for PowerPC/Layerscape GPIO interrupt, it should be "handle_edge_irq". Otherwise the system may lost some interrupts from the PIN's state changes.

2016-10-22drm/i915: Stop setting SNB min-freq-table 0 on powersave setupChris Wilson
The min-freq-table is an array of values that match each CPU frequency to an equivalent GPU frequency. Setting a single value of 0 on init is both illegal (generates an error from the PCU) and nonsensical. Let's see if we survive without that error.

2016-10-21cpufreq: intel_pstate: Set P-state upfront in performance modeRafael J. Wysocki
After commit a4675fbc4a7a (cpufreq: intel_pstate: Replace timers with utilization update callbacks) the cpufreq governor callbacks may not be invoked on NOHZ_FULL CPUs and, in particular, switching to the "performance" policy via sysfs may not have any effect on them. That is a problem, because it usually is desirable to squeeze the last bit of performance out of those CPUs, so work around it by setting the maximum P-state (within the limits) in intel_pstate_set_policy() upfront when the policy is CPUFREQ_POLICY_PERFORMANCE.

On certain platforms not all planes support the same set of rotations/reflections, so let's use the per-plane property for this. This is already a problem on SKL when we use the legay cursor plane as it only supports 0|180 whereas the universal planes support 0|90|180|270, and it will be a problem on CHV soon. v2: Use drm_plane_create_rotation_property() helper v3: Drop the BIT(), use INTEL_GEN() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> (v1) Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1474907460-10717-12-git-send-email-ville.syrjala@linux.intel.com
