Convert the Cadence I3C master to DT schema format. This fixes a warning as it is used in the i3c.yaml example. The "nintendo,nunchuk" is not documented by a schema, so change the example child device to something which is documented.

2022-05-03seccomp: Add wait_killable semantic to seccomp user notifierSargun Dhillon1-0/+10
This introduces a per-filter flag (SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV) that makes it so that when notifications are received by the supervisor the notifying process will transition to wait killable semantics. Although wait killable isn't a set of semantics formally exposed to userspace, the concept is searchable. If the notifying process is signaled prior to the notification being received by the userspace agent, it will be handled as normal. One quirk about how this is handled is that the notifying process only switches to TASK_KILLABLE if it receives a wakeup from either an addfd or a signal. This is to avoid an unnecessary wakeup of the notifying task. The reasons behind switching into wait_killable only after userspace receives the notification are: * Avoiding unncessary work - Often, workloads will perform work that they may abort (request racing comes to mind). This allows for syscalls to be aborted safely prior to the notification being received by the supervisor. In this, the supervisor doesn't end up doing work that the workload does not want to complete anyways. * Avoiding side effects - We don't want the syscall to be interruptible once the supervisor starts doing work because it may not be trivial to reverse the operation. For example, unmounting a file system may take a long time, and it's hard to rollback, or treat that as reentrant. * Avoid breaking runtimes - Various runtimes do not GC when they are during a syscall (or while running native code that subsequently calls a syscall). If many notifications are blocked, and not picked up by the supervisor, this can get the application into a bad state.

2022-05-03Docs: KVM: Add doc for the bitmap firmware registersRaghavendra Rao Ananta2-17/+96
Add the documentation for the bitmap firmware registers in hypercalls.rst and api.rst. This includes the details for KVM_REG_ARM_STD_BMAP, KVM_REG_ARM_STD_HYP_BMAP, and KVM_REG_ARM_VENDOR_HYP_BMAP registers. Since the document is growing to carry other hypercall related information, make necessary adjustments to present the document in a generic sense, rather than being PSCI focused.

GENI(generic interface) based Qualcomm Universal Peripheral controller can support multiple serial interfaces like SPI,UART and I2C. Unlike other I2C controllers, QUP I2C bindings are present in parent schema. Move it out from parent to an individual binding and let parent refer to child schema later on. Please note, current schema isn't complete as it misses out few properties and thus, add these missing properties along the process.

2022-05-03dt-bindings: display: rockchip: dw-hdmi: use "ref" as clock nameSascha Hauer1-2/+7
"vpll" is a misnomer. A clock input to a device should be named after the usage in the device, not after the clock that drives it. On the rk3568 the same clock is driven by the HPLL.

2022-05-02kunit: add ability to specify suite-level init and exit functionsDaniel Latypov1-8/+11
KUnit has support for setup/cleanup logic for each test case in a suite. But it lacks the ability to specify setup/cleanup for the entire suite itself. This can be used to do setup that is too expensive or cumbersome to do for each test. Or it can be used to do simpler things like log debug information after the suite completes. It's a fairly common feature, so the lack of it is noticeable. Some examples in other frameworks and languages: * https://docs.python.org/3/library/unittest.html#setupclass-and-teardownclass * https://google.github.io/googletest/reference/testing.html#Test::SetUpTestSuite Meta: This is very similar to this patch here: https://lore.kernel.org/linux-kselftest/20210805043503.20252-3-bvanassche@acm.org/ The changes from that patch: * pass in `struct kunit *` so users can do stuff like `kunit_info(suite, "debug message")` * makes sure the init failure is bubbled up as a failure * updates kunit-example-test.c to use a suite init * Updates kunit/usage.rst to mention the new support * some minor cosmetic things * use `suite_{init,exit}` instead of `{init/exit}_suite` * make suite init error message more consistent w/ test init * etc. Signed-off-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: David Gow <davidgow@google.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

2022-05-02dt: bindings: net: add bindings of WCN6750 for ath11kManikanta Pubbisetty1-109/+252
WCN6750 is the WLAN chip on Qualcomm Snapdragon SoC SC7280; Though being a PCIe based solution, it is not attached to the APSS processor (Application Processor SubSystem), it is instead attached to another tiny processor called WPSS Q6 processor (Wireless Processor SubSystem) on the SC7280 MSM, where the WLAN firmware runs, and it is the WLAN firmware running on the Q6 processor which enumerates WCN6750, as a result APPS processor would never know such a device being present in the system and would not detect the WCN6750 hardware unless and otherwise WCN6750 is registered as a platform device. This is the reason behind adding WCN6750 WLAN node in the device tree. Add WCN6750 wireless driver support, its based on ath11k driver.
