2022-11-28irqchip/irq-mtk-cirq: Add support for System CIRQ on MT8192AngeloGioacchino Del Regno
On some SoCs the System CIRQ register layout is slightly different, as there are more registers per function and in some cases other differences later in the layout: this is seen on at least MT8192, but it's also valid for some other "contemporary" SoCs both for Chromebooks and for smartphones. Add the new "v2" register layout and use it if the compatible "mediatek,mt8192-cirq" is found.

2022-11-28irqchip/irq-mtk-cirq: Move register offsets to const arrayAngeloGioacchino Del Regno
In preparation to add support for new SoCs having a different register layout, add an enumeration that documents register offsets and move the definitions for the same to a u32 array; Selecting the right register offsets array is done by adding an of_device_id array containing all of the currently supported compatible strings pointing to the "v1" offsets array (as data): since no devicetree declares the `mediatek,mtk-cirq` compatible without a SoC-specific one, it wasn't necessary to provide any legacy fallback. Every usage of the aforemementioned definitions was changed to get a register address through a newly introduced `mtk_cirq_reg()` accessor. This change brings no functional changes.

2022-11-28dt-bindings: interrupt-controller: mediatek,cirq: Migrate to dt schemaAngeloGioacchino Del Regno
Migrate mediatek,cirq.txt to dt schema as mediatek,mtk-cirq.yaml. While at it, I've also fixed some typos that were present in the original txt binding, as it was suggesting that the compatible string would have "mediatek,cirq" as compatible but, in reality, that's supposed to be "mediatek,mtk-cirq" instead. Little rewording on property descriptions also happened for them to be more concise.

2022-11-28net: wwan: iosm: fix incorrect skb lengthM Chetan Kumar
skb passed to network layer contains incorrect length. In mux aggregation protocol, the datagram block received from device contains block signature, packet & datagram header. The right skb len to be calculated by subracting datagram pad len from datagram length. Whereas in mux lite protocol, the skb contains single datagram so skb len is calculated by subtracting the packet offset from datagram header.

Tim Harvey reports that link modes which he does not expect to be supported are being advertised, and this is because of the workaround we have for PHYs that switch interface modes. Fix this up by checking whether rate matching will be used for the requested interface mode, and if rate matching will be used, perform validation only with the requested interface mode, rather than invoking this workaround.

2022-11-28gpiolib: fix memory leak in gpiochip_setup_dev()Zeng Heng
Here is a backtrace report about memory leak detected in gpiochip_setup_dev(): unreferenced object 0xffff88810b406400 (size 512): comm "python3", pid 1682, jiffies 4295346908 (age 24.090s) backtrace: kmalloc_trace device_add device_private_init at drivers/base/core.c:3361 (inlined by) device_add at drivers/base/core.c:3411 cdev_device_add gpiolib_cdev_register gpiochip_setup_dev gpiochip_add_data_with_key gcdev_register() & gcdev_unregister() would call device_add() & device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to register/unregister device. However, if device_add() succeeds, some resource (like struct device_private allocated by device_private_init()) is not released by device_del(). Therefore, after device_add() succeeds by gcdev_register(), it needs to call put_device() to release resource in the error handle path. Here we move forward the register of release function, and let it release every piece of resource by put_device() instead of kfree(). While at it, fix another subtle issue, i.e. when gc->ngpio is equal to 0, we still call kcalloc() and, in case of further error, kfree() on the ZERO_PTR pointer, which is not NULL. It's not a bug per se, but rather waste of the resources and potentially wrong expectation about contents of the gdev->descs variable.

2022-11-26irqchip/al-fic: Drop obsolete dependency on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

2022-11-26irqchip: gic-pm: Use pm_runtime_resume_and_get() in gic_probe()Shang XiaoJing
gic_probe() calls pm_runtime_get_sync() and added fail path as rpm_put to put usage_counter. However, pm_runtime_get_sync() will increment usage_counter even it failed. Fix it by replacing it with pm_runtime_resume_and_get() to keep usage counter balanced.

HTVECINTC stands for "HyperTransport Interrupts" that described in Section 14.3 of "Loongson 3A5000 Processor Reference Manual". For more information please refer Documentation/loongarch/irq-chip-model.rst. Though the extended model is the recommended one, there are still some legacy model machines. So we add ACPI init support for HTVECINTC.

2022-11-26ACPI / PCI: fix LPIC IRQ model default PCI IRQ polarityJianmin Lv
On LoongArch based systems, the PCI devices (e.g. SATA controllers and PCI-to-PCI bridge controllers) in Loongson chipsets output high-level interrupt signal to the interrupt controller they are connected (see Loongson 7A1000 Bridge User Manual v2.00, sec 5.3, "For the bridge chip, AC97 DMA interrupts are edge triggered, gpio interrupts can be configured to be level triggered or edge triggered as needed, and the rest of the interrupts are level triggered and active high."), while the IRQs are active low from the perspective of PCI (see Conventional PCI spec r3.0, sec 2.2.6, "Interrupts on PCI are optional and defined as level sensitive, asserted low."), which means that the interrupt output of PCI devices plugged into PCI-to-PCI bridges of Loongson chipset will be also converted to high-level. So high level triggered type is required to be passed to acpi_register_gsi() when creating mappings for PCI devices.
