2021-08-16serial: sh-sci: fix break handling for sysrqUlrich Hecht
This fixes two issues that cause the sysrq sequence to be inadvertently aborted on SCIF serial consoles: - a NUL character remains in the RX queue after a break has been detected, which is then passed on to uart_handle_sysrq_char() - the break interrupt is handled twice on controllers with multiplexed ERI and BRI interrupts Signed-off-by: Ulrich Hecht <uli+renesas@fpond.eu> Link: https://lore.kernel.org/r/20210816162201.28801-1-uli+renesas@fpond.eu Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2021-08-16PM: domains: Add support for 'required-opps' to set default perf stateRajendra Nayak
Some devices within power domains with performance states do not support DVFS, but still need to vote on a default/static state while they are active. They can express this using the 'required-opps' property in device tree, which points to the phandle of the OPP supported by the corresponding power-domains. Add support to parse this information from DT and then set the specified performance state during attach and drop it on detach. runtime suspend/resume callbacks already have logic to drop/set the vote as needed and should take care of dropping the default perf state vote on runtime suspend and restore it back on runtime resume.

2021-08-16Revert "media: device property: Call fwnode_graph_get_endpoint_by_id() for ↵Daniel Scally
fwnode->secondary" This reverts commit acd418bfcfc415cf5e6414b6d1c6acfec850f290. Checking for endpoints against fwnode->secondary in fwnode_graph_get_next_endpoint() is a better way to do this since that function is also used in a bunch of other places, for instance sensor drivers checking that they do have an endpoint connected during probe.

2021-08-16device property: Check fwnode->secondary in fwnode_graph_get_next_endpoint()Daniel Scally
Sensor drivers often check for an endpoint to make sure that they're connected to a consuming device like a CIO2 during .probe(). Some of those endpoints might be in the form of software_nodes assigned as a secondary to the device's fwnode_handle. Account for this possibility in fwnode_graph_get_next_endpoint() to avoid having to do it in the sensor drivers themselves.

2021-08-16ACPI: platform-profile: call sysfs_notify() from platform_profile_store()Hans de Goede
Drivers like thinkpad_acpi and ideapad_laptop call the platform_profile_notify() helper when the profile is changed by hardware (the embedded-controller/EC) in response to an EC handled hotkey. This allows userspace to monitor for such changes by polling for POLLPRI on the platform_profile sysfs file. But the profile can also be changed underneath a userspace program monitoring it by anonther userspace program storing a new value. Add a sysfs_notify() call to platform_profile_store(), so that userspace programs monitoring for changes also get notified in this case. Also update the documentation to document that POLLPRI polling can be used to watch for changes. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J.

Previously this stayed unnoticed on Nexus 7 because pin control was enabled by default after rebooting from downstream kernel, which uses driver that enables the bit and charger registers are non-volatile until power supply (battery) is disconnected.

2021-08-16PCI: rcar: Add L1 link state fix into data abort hookMarek Vasut
When the link is in L1, hardware should return it to L0 automatically whenever a transaction targets a component on the other end of the link (PCIe r5.0, sec 5.2). The R-Car PCIe controller doesn't handle this transition correctly. If the link is not in L0, an MMIO transaction targeting a downstream device fails, and the controller reports an ARM imprecise external abort. Work around this by hooking the abort handler so the driver can detect this situation and help the hardware complete the link state transition. When the R-Car controller receives a PM_ENTER_L1 DLLP from the downstream component, it sets PMEL1RX bit in PMSR register, but then the controller enters some sort of in-between state. A subsequent MMIO transaction will fail, resulting in the external abort. The abort handler detects this condition and completes the link state transition by setting the L1IATN bit in PMCTLR and waiting for the link state transition to complete.

We currently only support that if all required devices are represented by their own Device Tree nodes complete with compatible strings. However, not everyone is happy with adding empty nodes that provide no additional device information into the Device Tree. Rather than have a plethora of mostly empty, function-less drivers in MFD, we'll support those simple cases in here instead via MFD cells.

2021-08-16mfd/cpuidle: ux500: Rename driver symbolLinus Walleij
The PRCMU driver defines this as a DT node but there are no bindings for it and it needs no data from the device tree. Just spawn the device directly in the same way as the watchdog. Name it "db8500-cpuidle" since there are no ambitions to support any more SoCs than this one. This rids this annoying boot message: [ 0.032610] cpuidle-dbx500: Failed to locate of_node [id: 0] However I think the device still spawns and work just fine, despite not finding a device tree node.
