2024-10-17gpio: sysfs: constify gpio classBartosz Golaszewski
All class functions used here take a const pointer to the class structure. We can constify gpio_class. While at it: remove a stray newline and use a tab in the struct definition for consistency with the line above.

2024-10-14gpio: add support for FTDI's MPSSE as GPIOMary Strodl
FTDI FT2232H is a USB to GPIO chip. Sealevel produces some devices with this chip. FT2232H presents itself as a composite device with two interfaces (each is an "MPSSE"). Each MPSSE has two banks (high and low) of 8 GPIO each. I believe some MPSSE's have only one bank, but I don't know how to identify them (I don't have any for testing) and as a result are unsupported for the time being. Additionally, this driver provides software polling-based interrupts for edge detection. For the Sealevel device I have to test with, this works well because there is hardware debouncing. From talking to Sealevel's people, this is their preferred way to do edge detection.

2024-10-14gpio: aspeed: Support G7 Aspeed gpio controllerBilly Tsai
In the 7th generation of the SoC from Aspeed, the control logic of the GPIO controller has been updated to support per-pin control. Each pin now has its own 32-bit register, allowing for individual control of the pin's value, direction, interrupt type, and other settings. The permission for coprocessor access is supported by the hardware but hasn't been implemented in the current patch.

2024-10-14gpio: aspeed: Change the macro to support deferred probeBilly Tsai
Use module_platform_driver() to replace module_platform_driver_probe(). The former utilizes platform_driver_register(), which allows the driver to defer probing when it doesn't acquire the necessary resources due to probe order. In contrast, the latter uses __platform_driver_probe(), which includes the comment "Note that this is incompatible with deferred probing." Since our GPIO driver requires access to the clock resource, the former is more suitable.

This is because is it done very early in the exception and there are not enough registers available to keep a pointer to thread struct. However, dcbz instruction is buggy and doesn't update DAR register on fault. That is detected and generates a call to FixupDAR workaround which updates DAR copy in thread struct but doesn't fix DAR register. Let's fix DAR in addition to the update of DAR copy in thread struct.

But the allocation code still attached a CPU notifier callback to this ring buffer. When a CPU is added, the callback will happen and another per-cpu buffer is created for the ring buffer. But for boot mapped buffers, there is no room to add another one (as they were all created already). The result of calling the CPU hotplug notifier on a boot mapped ring buffer is unpredictable and could lead to a system crash. If the ring buffer is boot mapped simply do not attach the CPU notifier to it" * tag 'trace-ringbuffer-v6.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Do not have boot mapped buffers hook to CPU hotplug
2024-10-10of: Skip kunit tests when arm64+ACPI doesn't populate root nodeStephen Boyd
A root node is required to apply DT overlays. A root node is usually present after commit 7b937cc243e5 ("of: Create of_root if no dtb provided by firmware"), except for on arm64 systems booted with ACPI tables. In that case, the root node is intentionally not populated because it would "allow DT devices to be instantiated atop an ACPI base system"[1]. Introduce an OF function that skips the kunit test if the root node isn't populated. Limit the test to when both CONFIG_ARM64 and CONFIG_ACPI are set, because otherwise the lack of a root node is a bug. Make the function private and take a kunit test parameter so that it can't be abused to test for the presence of the root node in non-test code. Use this function to skip tests that require the root node. Currently that's the DT tests and any tests that apply overlays.
