mfd: Add ACPI support to Kontron PLD driver

2020-09-30T16:46:27Z

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.

mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PAC

2020-09-30T16:46:21Z

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.

mfd: syscon: Don't free allocated name for regmap_config

2020-09-30T15:25:16Z

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. Move the free on the error path, and keep it forever otherwise. Fixes: e15d7f2b81d2 ("mfd: syscon: Use a unique name with regmap_config") Signed-off-by: Marc Zyngier Signed-off-by: Lee Jones
