2020-05-22mb/pcengines/apu1/platform_cfg.h: Unset UsbRxMode to avoid platform reset issuePiotr Kleinschmidt
On PC Engines apu1 there were issues with cold reset. Platform hangs in boot path after performing reset using CF9h. CB:10549 (amd/sb800: Make UsbRxMode per-board customizable) mentions a similar issue, and added a configuration macro for it. That error is also described in AMD SB800 Family Product Errata, section 15 USB Resets Asynchronously With Port CF9h Hard Reset. This workaround simply non-execute USB configuration during boot and hence no reset via CF9h is done.

2020-05-22soc/intel/tigerlake: Provide SoundWire controller propertiesDuncan Laurie
The Intel Tigerlake SoundWire controller has 4 master links which are configured differently depending on the external crystal oscillator which is connected to the PCH. This function will read the PCH PMC EPOC register to determine the frequency and then fill out the master link entries with the correct table values. The frequency is also provided directly in a custom "ip-clock" property which will be added to the link descriptor and passed to the OS driver so it can know the clock rate of the master.

2020-05-22drivers/intel/soundwire: Add Intel SoundWire controller driverDuncan Laurie
This driver provides support for Intel SoundWire controllers. It is intended to be used by multiple Intel SoCs and relies on retrieving controller/master information from the SoC itself. As such it provides a function that must be implemented by the SoC to fill out this structure. The Intel SoundWire driver in the Linux kernel expects firmware to inform it which master links are unused by adding a custom property to the link descriptor. This is done by looking for any children attached to the device that use each link and disabling the ones that are unused. Mainboards will enable this driver and define the controller in devicetree.cb in order provide the required ACPI tables, but the mainboard should not need to provide any configuration itself as that should all come from the SoC directly. This was tested with the volteer board by adding this controller and a codec to devicetree.cb and ensuring that the properties are all present, including the custom properties for the device clock and quirk mask for disabled links.

2020-05-21nb/intel/sandybridge: Refactor IOSAV_SUBSEQUENCE againAngel Pons
To replace the register writes with assignments to struct fields, we would need to have the values as parameters of a single macro. So, split the raw value of `IOSAV_n_SP_CMD_CTRL_ch` in two parts. Note that the single command that sets bit 17 is likely wrong, but it will be fixed after refactoring. For now, we'll treat it as part of `ranksel`. Move the parameters of `ADDR_UPDATE` into the top-level IOSAV macro. Hopefully, this will be enough to replace the underlying implementation. Line length limits are not for review. Breaking the lines unnecessarily complicates search and replace operations, and wil be taken care of in subsequent commits. Tested with BUILD_TIMELESS=1, ASUS P8Z77-V LX2 remains unchanged.

2020-05-21acpi/soundwire: Add functions to generate SoundWire propertiesDuncan Laurie
This change uses the previously added SoundWire definitions to provide functions that generate ACPI Device Properties for SoundWire controllers and codecs. A SoundWire controller driver should populate `struct soundwire_controller` and pass it to soundwire_gen_controller(). This will add all of the defined master links provided by the controller. A SoundWire codec driver should populate the necessary members in struct soundwire_codec and pass it to soundwire_gen_codec(). Several properties are optional and depend on whether the codec itself supports certain features and behaviors. The goal of this interface is to handle all of the properties defined in the SoundWire Discovery and Configuration Specification Version 1.0 so that controller and codec drivers do not need to all have code for writing standard properties. Both of these functions also provide a callback method for adding custom properties that are not defined by the SoundWire DisCo Specification. These properties may be required by OS drivers but are outside of the scope of the SoundWire specification itself. This code is tested with controller, codec, and mainboard implementations in subsequent commits.

2020-05-20google/trogdor: Fix ram_code and sku_id strappingsJulius Werner
I'm not quite sure what happened when we first added the code for Trogdor strappings but something clearly seems to be wrong. First of all, on newer schematics the RAM_ID_1 pin is actually pin 19, not pin 91. It only used to be 91 on rev0. Whether that was an intentional change or someone just swapped the digits on accident at some point, we're not quite sure anymore, but it seems to be 19 going forward so that is what we should be programming. (ram_code wasn't used for anything on Trogdor rev0 so we don't care about adding backwards-compatibility for that.) The sku_id pins are also somewhat out of whack: first of all, a new SKU_ID_2 pin was added for rev1 that wasn't there on rev0. Second, SKU_ID_0 is not GPIO_114. In fact, it has never been GPIO_114. I have no idea how that number got there. Anyway, fix it. (Like with the ram_code, SKU IDs were also not used for rev0 so we won't make this backwards-compatible.)

2020-05-20device/pci_device: Add notion of "hidden" PCI devicesTim Wawrzynczak
On some SoCs, there are PCI devices that may get hidden from PCI enumeration by platform firmware. Because the Vendor ID reads back as 0xffffffff, it appears that there is no PCI device located at that BDF. However, because the device does exist, designers may wish to hang its PCI resources off of a real __pci_driver, as well as have it participate in ACPI table generation. This patch extends the semantics of the 'hidden' keyword in devicetree.cb. If a device now uses 'hidden' instead of 'on', then it will be assumed during PCI enumeration that the device indeed does exist, and it will not be removed as a "leftover device." This allows child devices to be enumerated correctly and also PCI resources can be designated from the {read,set}_resources callbacks. It should be noted that as of this commit, there are precisely 0 devices using 'hidden' in their devicetree.cb files, so this should be a safe thing to do. Later patches will begin moving PCI resources from random places (typically hung off of fixed SA and LPC) into the PMC device (procedure will vary per- platform).
