2020-09-30leds: pca963x: register LEDs immediately after parsing, get rid of platdataMarek Behún
Register LEDs immediately after parsing their properties. This allows us to get rid of platdata, and since no one in tree uses header linux/platform_data/leds-pca963x.h, remove it.

2020-09-30mfd: Add ACPI support to Kontron PLD driverMichael Brunner
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.

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.

2020-09-30ice: preserve NVM capabilities in safe modeJacob Keller
If the driver initializes in safe mode, it will call ice_set_safe_mode_caps. This results in clearing the capabilities structures, in order to set them up for operating in safe mode, ensuring many features are disabled. This has a side effect of also clearing the capability bits that relate to NVM update. The result is that the device driver will not indicate support for unified update, even if the firmware is capable. Fix this by adding the relevant capability fields to the list of values we preserve. To simplify the code, use a common_cap structure instead of a handful of local variables. To reduce some duplication of the capability name, introduce a couple of macros used to restore the capabilities values from the cached copy.

2020-09-30ice: increase maximum wait time for flash write commandsJacob Keller
The ice driver needs to wait for a firmware response to each command to write a block of data to the scratch area used to update the device firmware. The driver currently waits for up to 1 second for this to be returned. It turns out that firmware might take longer than 1 second to return a completion in some cases. If this happens, the flash update will fail to complete. Fix this by increasing the maximum time that the driver will wait for both writing a block of data, and for activating the new NVM bank. The timeout for an erase command is already several minutes, as the firmware had to erase the entire bank which was already expected to take a minute or more in the worst case. In the case where firmware really won't respond, we will now take longer to fail. However, this ensures that if the firmware is simply slow to respond, the flash update can still complete. This new maximum timeout should not adversely increase the update time, as the implementation for wait_event_interruptible_timeout, and should wake very soon after we get a completion event. It is better for a flash update be slow but still succeed than to fail because we gave up too quickly.
