2015-08-19nand: pxa3xx: Increase READ_ID buffer and make the size staticEzequiel García
The read ID count should be made as large as the maximum READ_ID size, so there's no need to have dynamic size. This commit sets the hardware maximum read ID count, which should be more than enough on all cases. Also, we get rid of the read_id_bytes, and use a macro instead.

2015-08-19mtd: nand: pxa3xx-nand: fix random command timeoutsRobert Jarzmik
When 2 commands are submitted in a row, and the second is very quick, the completion of the second command might never come. This happens especially if the second command is quick, such as a status read after an erase. The issue is that in the interrupt handler, the status bits are cleared after the new command is issued. There is a small temporal window where this happens : - the previous command has set the command done bit - the ready for a command bit is set - the handler submits the next command - just then, the command completes, and the command done bit is still set - the handler clears the "previous" command done bit - the handler exits In this flow, the "command done" of the next command will never trigger a new interrupt to finish the status command, as it was cleared for both commands. Fix this by clearing the status bit before submitting a new command.

2015-08-20irqchip/crossbar: Restore set_wake functionalityGrygorii Strashko
The TI crossbar irqchip doesn't provides any facility to configure the wakeup sources, but the conversion to hierarchical irqdomains set the irq_set_wake callback to irq_chip_set_wake_parent. The parent chip (OMAP wakeupgen) has no irq_set_wake function either so the call will fail with -ENOSYS. As a result the irq_set_wake() call in the resume path will trigger an 'Unbalanced wake disable' warning. Before the conversion the GIC irqchip was the top level irqchip and correctly flagged with IRQCHIP_SKIP_SET_WAKE. Restore the correct behaviour by removing the irq_set_type callback from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which lets the irq_set_irq_wake() call from the driver succeed.

2015-08-20irqchip/crossbar: Restore the mask on suspend behaviourGrygorii Strashko
The ARM GIC requires that all interrupts which are not used as a wakeup source have to be masked during suspend. The conversion of the crossbar irqchip to hierarchical irq domains failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND flag and therefor broke the suspend requirement of the GIC. Before the conversion the flags were visible because the GIC was the top level irqchip. After the conversion the crossbar irqchip is the top level irq chip whose flags are evaluated in suspend_device_irq(). As the flag is not set the masking of the non-wakeup irqs is not invoked which breaks suspend. Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the GIC interrupts get masked properly.

2015-08-20genirq: Don't return ENOSYS in irq_chip_retrigger_hierarchyGrygorii Strashko
irq_chip_retrigger_hierarchy() returns -ENOSYS if it was not able to find at least one .irq_retrigger() callback implemented in the IRQ domain hierarchy. That's wrong, because check_irq_resend() expects a 0 return value from the callback in case that the hardware assisted resend was not possible. If the return value is non zero the core code assumes hardware resend success and the software resend is not invoked. This results in lost interrupts on platforms where none of the parent irq chips in the hierarchy implements the retrigger callback. This is observable on TI OMAP, where the hierarchy is: ARM GIC <- OMAP wakeupgen <- TI Crossbar Return 0 instead so the software resend mechanism gets invoked.

When the nand is first probe, and upon the first command start, the status bits should be cleared before the interrupts are unmasked. The bug is tricky : if the bootloader left a status bit set, the unmasking of interrupts does trigger the interrupt handler before the first command is issued, blocking the good behavior of the nand. The same would happen if in pxa3xx_nand code flow a status bit is left, and then a command is started.

2015-08-19PCI: Tolerate hierarchies with no Root PortYijing Wang
We should not assume any particular hardware topology. Commit d0751b98dfa3 ("PCI: Add dev->has_secondary_link to track downstream PCIe links") relied on the assumption that every PCIe hierarchy is rooted at a Root Port. But we can't rely on any assumption about what hardware we will find; we just have to deal with the world as it is. On some platforms, PCIe devices (endpoints, switch upstream ports, etc.) appear directly on the root bus, and there is no Root Port in the PCI bus hierarchy. For example, Meelis observed these top-level devices on a Sparc V245: 0000:02:00.0 PCI bridge to [bus 03-0d] Switch Upstream Port 0001:02:00.0 PCI bridge to [bus 03] PCIe to PCI/PCI-X Bridge These devices *look* like they have links going upstream, but there really are no upstream devices. In set_pcie_port_type(), we used the parent device to figure out which side of a switch port has a link, so if the parent device did not exist, we dereferenced a NULL parent pointer. Check whether the parent device exists before dereferencing it. Meelis observed this oops on Sparc V245 and T2000. Ben Herrenschmidt says this is also possible on IBM PowerVM guests on PowerPC.

This patch adds a queue limits so a driver with such constraints can set to allow requests that would have been unnecessarily split. The new gaps check takes the request_queue as a parameter to simplify the logic around invoking this function. This new limit makes the queue flag redundant, so removing it and all usage.

2015-08-19Input: cros_ec_keyb - replace KEYBOARD_CROS_EC dependencyJavier Martinez Canillas
The ChromeOS EC keyboard driver config depends on CROS_EC_PROTO but MFD_CROS_EC selects CROS_EC_PROTO instead. Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since the platform device that is matched with the keyboard driver is registered by the ChromeOS EC mfd driver, KEYBOARD_CROS_EC really should depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the driver to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

2015-08-19dmaengine: mv_xor: optimize performance by using a subset of the XOR channelsThomas Petazzoni
Due to how async_tx behaves internally, having more XOR channels than CPUs is actually hurting performance more than it improves it, because memcpy requests get scheduled on a different channel than the XOR requests, but async_tx will still wait for the completion of the memcpy requests before scheduling the XOR requests. It is in fact more efficient to have at most one channel per CPU, which this patch implements by limiting the number of channels per engine, and the number of engines registered depending on the number of availables CPUs. Marvell platforms are currently available in one CPU, two CPUs and four CPUs configurations: - in the configurations with one CPU, only one channel from one engine is used. - in the configurations with two CPUs, only one channel from each engine is used (they are two XOR engines) - in the configurations with four CPUs, both channels of both engines are used.

2015-08-19dmaengine: mv_xor: remove support for dmacap,* DT propertiesThomas Petazzoni
The only reason why we had dmacap,* properties is because back when DMA_MEMSET was supported, only one out of the two channels per engine could do a memset operation. But this is something that the driver already knows anyway, and since then, the DMA_MEMSET support has been removed. The driver is already well aware of what each channel supports and the one to one mapping between Linux specific implementation details (such as dmacap,interrupt enabling DMA_INTERRUPT) and DT properties is a good indication that these DT properties are wrong. Therefore, this commit simply gets rid of these dmacap,* properties, they are now ignored, and the driver is responsible for knowing the capabilities of the hardware with regard to the dmaengine subsystem expectations.

2015-08-19ALSA: usb-audio: Fix runtime PM unbalanceTakashi Iwai
The fix for deadlock in PM in commit [1ee23fe07ee8: ALSA: usb-audio: Fix deadlocks at resuming] introduced a new check of in_pm flag. However, the brainless patch author evaluated it in a wrong way (logical AND instead of logical OR), thus usb_autopm_get_interface() is wrongly called at probing, leading to unbalance of runtime PM refcount. This patch fixes it by correcting the logic.

2015-08-19ath10k: free collected fw stats memory if .pull_fw_stats failsRaja Mani
If .pull_fw_stats() fails for some reason while processing fw stats event, collected pdev/vdev/peer stats just before the failure should be freed. This is unlikely to happen, just code review catch. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-08-19ath10k: ensure pktlog disable cmd reaches fw before pdev suspendRaja Mani
Found incorrect sequence in ath10k_core_stop() where wmi pktlog disable cmd is passed from ath10k_debug_stop() to firmware immediately after wmi pdev suspend cmd. Firmware will not accept any wmi cmd after receiving wmi pdev suspend cmd. Fix this issue in ath10k_core_stop() by moving ath10k_debug_stop() just before sending pdev suspend cmd. So that pktlog disable cmd will get passed before pdev suspend cmd. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-08-19[media] mantis: Fix error handling in mantis_dma_init()Fabio Estevam
Current code assigns 0 to variable 'err', which makes mantis_dma_init() to return success even if mantis_alloc_buffers() fails. Fix it by checking the return value from mantis_alloc_buffers() and propagating it in the case of error.
