GPIO_ACTIVE_x flags are not correct in the context of interrupt flags. These are simple defines so they could be used in DTS but they will not have the same meaning: 1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE 2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING Correct the interrupt flags, assuming the author of the code wanted same logical behavior behind the name "ACTIVE_xxx", this is: ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW Signed-off-by:

Recent Kontron COMe modules identify the PLD device using the hardware id KEM0001 in the ACPI table. This patch adds support for probing the device using the HID and also retrieving the resources. As this is not available for all products, the DMI based detection still needs to be around for older systems. It is executed if no matching ACPI HID is found during registering the platform driver or no specific device id is forced. If a device is detected using ACPI and no resource information is available, the default io resource is used. Forcing a device id with the force_device_id parameter and therefore manually generating a platform device takes precedence over ACPI during probing. Signed-off-by:

This patch implements the basic functions of the BMC chip for some Intel FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the Intel MAX 10 CPLD. This BMC chip is connected to the FPGA by a SPI bus. To provide direct register access from the FPGA, the "SPI slave to Avalon Master Bridge" (spi-avmm) IP is integrated in the chip. It converts encoded streams of bytes from the host to the internal register read/write on the Avalon bus. So This driver uses the regmap-spi-avmm for register accessing. Signed-off-by:

Also apply a few smaller improvements: - document that the only possible I2C slave address is 0x60 as per the datasheet and fix the second example accordingly - The definition of "xxx-in-supply" was generic, thus define in detail the possible cases for each chip variant - remove "MFD driver" from the title as it is implementation specific - replace "PMIC" with "buck converter" in title as it is more informative Signed-off-by:

The name allocated for the regmap_config structure is freed pretty early, right after the registration of the MMIO region. Unfortunately, that doesn't follow the life cycle that debugfs expects, as it can access the name field long after the free has occurred.

When changing to use suspend-to-idle to save power, the PMIC irq can not wakeup the system due to lack of wakeup capability, which will cause the sub-irqs (such as power key) of the PMIC can not wake up the system. Thus we can add the wakeup capability for PMIC irq to solve this issue, as well as removing the IRQF_NO_SUSPEND flag to allow PMIC irq to be a wakeup source. Reported-by:

There are I2C devices which contain several different functions but doesn't require any special access functions. For these kind of drivers an I2C regmap should be enough. Create an I2C driver which creates an I2C regmap and enumerates its children. If a device wants to use this as its MFD core driver, it has to add an individual compatible string. It may provide its own regmap configuration. Subdevices can use dev_get_regmap() on the parent to get their regmap instance. Signed-off-by:

Pull io_uring fixes from Jens Axboe: "A few differerent things in here. Seems like syzbot got some more io_uring bits wired up, and we got a handful of reports and the associated fixes are in here. General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented).

Commit 1355c31e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()") converted parisc to use generic version of pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for PMD. Restore the original version of pmd_alloc_one() for parisc, just use GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and memset.
