The jc42 driver passes I2C client's name as hwmon device name. In case of device tree probed devices this ends up being part of the compatible string, "jc-42.4-temp". This name contains hyphens and the hwmon core doesn't like this: jc42 2-0018: hwmon: 'jc-42.4-temp' is not a valid name attribute, please fix This changes the name to "jc42" which doesn't have any illegal characters.

2020-04-17of: unittest: kmemleak in duplicate property updateFrank Rowand2-10/+25
kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 5 of 5. When overlay 'overlay_bad_add_dup_prop' is applied, the apply code properly detects that a memory leak will occur if the overlay is removed since the duplicate property is located in a base devicetree node and reports via printk(): OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail The overlay is removed when the apply code detects multiple changesets modifying the same property. This is reported via printk(): OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail As a result of this error, the overlay is removed resulting in the expected memory leak. Add another device node level to the overlay so that the duplicate property is located in a node added by the overlay, thus no memory leak will occur when the overlay is removed. Thus users of kmemleak will not have to debug this leak in the future.

Taking an interrupt (like the one being reconfigured) would lead to a deadlock. A solution to this is: - Reorder the locking so that meson_gpio_irq_update_bits takes the lock itself at all times, instead of relying on the caller to lock or not, hence making the RMW sequence atomic, - Rework the critical section in meson_gpio_irq_request_channel to only cover the allocation itself, and let the gpio_irq_sel_pin callback deal with its own locking if required, - Take the private spin-lock with interrupts disabled at all times Reviewed-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

2020-04-17irqchip/ti-sci-inta: Fix processing of masked irqsGrygorii Strashko1-1/+2
The ti_sci_inta_irq_handler() does not take into account INTA IRQs state (masked/unmasked) as it uses INTA_STATUS_CLEAR_j register to get INTA IRQs status, which provides raw status value. This causes hard IRQ handlers to be called or threaded handlers to be scheduled many times even if corresponding INTA IRQ is masked. Above, first of all, affects the LEVEL interrupts processing and causes unexpected behavior up the system stack or crash. Fix it by using the Interrupt Masked Status INTA_STATUSM_j register which provides masked INTA IRQs status.

After commit bfcb813203e619a8960a819bf533ad2a108d8105 ("net: dsa: configure the MTU for switch ports") my Lamobo R1 platform which uses an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail by rejecting a MTU of 1536. The reason for that is that the DMA capabilities are not readable on this version of the IP, and there is also no 'tx-fifo-depth' property being provided in Device Tree. The property is documented as optional, and is not provided. Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so provide these values through platform data as an immediate fix until various Device Tree sources get updated accordingly.

2020-04-16irqchip/gic-v4.1: Add support for VPENDBASER's Dirty+Valid signalingMarc Zyngier2-4/+26
When a vPE is made resident, the GIC starts parsing the virtual pending table to deliver pending interrupts. This takes place asynchronously, and can at times take a long while. Long enough that the vcpu enters the guest and hits WFI before any interrupt has been signaled yet. The vcpu then exits, blocks, and now gets a doorbell. Rince, repeat. In order to avoid the above, a (optional on GICv4, mandatory on v4.1) feature allows the GIC to feedback to the hypervisor whether it is done parsing the VPT by clearing the GICR_VPENDBASER.Dirty bit. The hypervisor can then wait until the GIC is ready before actually running the vPE. Plug the detection code as well as polling on vPE schedule. While at it, tidy-up the kernel message that displays the GICv4 optional features. Reviewed-by: Zenghui Yu <yuzenghui@huawei.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

2020-04-15net: mscc: ocelot: fix untagged packet drops when enslaving to vlan aware bridgeVladimir Oltean3-47/+44
To rehash a previous explanation given in commit 1c44ce560b4d ("net: mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is up"), the switch driver operates the in a mode where a single VLAN can be transmitted as untagged on a particular egress port. That is the "native VLAN on trunk port" use case. The configuration for this native VLAN is driven in 2 ways: - Set the egress port rewriter to strip the VLAN tag for the native VID (as it is egress-untagged, after all). - Configure the ingress port to drop untagged and priority-tagged traffic, if there is no native VLAN. The intention of this setting is that a trunk port with no native VLAN should not accept untagged traffic. Since both of the above configurations for the native VLAN should only be done if VLAN awareness is requested, they are actually done from the ocelot_port_vlan_filtering function, after the basic procedure of toggling the VLAN awareness flag of the port. But there's a problem with that simplistic approach: we are trying to juggle with 2 independent variables from a single function: - Native VLAN of the port - its value is held in port->vid. - VLAN awareness state of the port - currently there are some issues here, more on that later*. The actual problem can be seen when enslaving the switch ports to a VLAN filtering bridge: 0. The driver configures a pvid of zero for each port, when in standalone mode. While the bridge configures a default_pvid of 1 for each port that gets added as a slave to it. 1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true. The VLAN-filtering-dependent portion of the native VLAN configuration is done, considering that the native VLAN is 0. 2. The bridge calls ocelot_vlan_add with vid=1, pvid=true, untagged=true. The native VLAN changes to 1 (change which gets propagated to hardware). 3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the VLAN-filtering-dependent portion of the native VLAN configuration, for the new native VLAN of 1. One can notice that after toggling "ip link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0 type bridge vlan_filtering 1", the new native VLAN finally makes it through and untagged traffic finally starts flowing again. But obviously that shouldn't be needed. So it is clear that 2 independent variables need to both re-trigger the native VLAN configuration. So we introduce the second variable as ocelot_port->vlan_aware. *Actually both the DSA Felix driver and the Ocelot driver already had each its own variable: - Ocelot: ocelot_port_private->vlan_aware - Felix: dsa_port->vlan_filtering but the common Ocelot library needs to work with a single, common, variable, so there is some refactoring done to move the vlan_aware property from the private structure into the common ocelot_port structure.

2020-04-15i2c: designware: platdrv: Remove DPM_FLAG_SMART_SUSPEND flag on BYT and CHTHans de Goede1-4/+10
We already set DPM_FLAG_SMART_PREPARE, so we completely skip all callbacks (other then prepare) where possible, quoting from dw_i2c_plat_prepare(): /* * If the ACPI companion device object is present for this device, it * may be accessed during suspend and resume of other devices via I2C * operation regions, so tell the PM core and middle layers to avoid * skipping system suspend/resume callbacks for it in that case. */ return !has_acpi_companion(dev); Also setting the DPM_FLAG_SMART_SUSPEND will cause acpi_subsys_suspend() to leave the controller runtime-suspended even if dw_i2c_plat_prepare() returned 0. Leaving the controller runtime-suspended normally, when the I2C controller is suspended during the suspend_late phase, is not an issue because the pm_runtime_get_sync() done by i2c_dw_xfer() will (runtime-)resume it. But for dw I2C controllers on Bay- and Cherry-Trail devices acpi_lpss.c leaves the controller alive until the suspend_noirq phase, because it may be used by the _PS3 ACPI methods of PCI devices and PCI devices are left powered on until the suspend_noirq phase. Between the suspend_late and resume_early phases runtime-pm is disabled. So for any ACPI I2C OPRegion accesses done after the suspend_late phase, the pm_runtime_get_sync() done by i2c_dw_xfer() is a no-op and the controller is left runtime-suspended. i2c_dw_xfer() has a check to catch this condition (rather then waiting for the I2C transfer to timeout because the controller is suspended). acpi_subsys_suspend() leaving the controller runtime-suspended in combination with an ACPI I2C OPRegion access done after the suspend_late phase triggers this check, leading to the following error being logged on a Bay Trail based Lenovo Thinkpad 8 tablet: [ 93.275882] i2c_designware 80860F41:00: Transfer while suspended [ 93.275993] WARNING: CPU: 0 PID: 412 at drivers/i2c/busses/i2c-designware-master.c:429 i2c_dw_xfer+0x239/0x280 ...

So since on BYT and CHT platforms we want ACPI I2c OPRegion accesses to work until the suspend_noirq phase, we need the controller to be runtime-resumed during the suspend phase if it is runtime-suspended suspended at that time. This means that we must not set the DPM_FLAG_SMART_SUSPEND on these platforms. On BYT and CHT we already have a special ACCESS_NO_IRQ_SUSPEND flag to make sure the controller stays functional until the suspend_noirq phase. This commit makes the driver not set the DPM_FLAG_SMART_SUSPEND flag when that flag is set.
