2022-08-24ec/google/chromeec/acpi: Add support for DPTF oem variable event notifyTony Huang
The agah EC code will monitor adapter current to choose corresponding DPTF oem variable table. When it changes, this event will send to the ACPI FW through host event and then pass onto the DPTF kernel driver. This patch adds support for that feature. BUG=b:238921409 TEST=add Printf() calls to the ACPI, and check these Printf() will show up in the kernel log when EC send oem variable table change notify.

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

2022-03-17ec/chromeec/ec_smbios: Set system manufacturer for ChromeOS devicesMatt DeVillier
Currently, many Linux drivers use DMI quirks to identify ChromeOS devices and handle them accordingly: namely they look for the SMBIOS system manufactuer to be "GOOGLE" or "Google", and the bios-vendor to be coreboot. Historically this was consistently the case, but recent model ChromeOS devices allow the OEM to set the mainboard manufacturer, which is also the default system manufacturer. This breaks many DMI quirks, notably ones used by SOF (sound open firmware) for audio. To fix this, set the system manufactuer for ChromeOS devices to "Google" for devices selecting CONFIG_EC_GOOGLE_CHROMEEC_SKUID, leaving the OEM customization in place for the mainboard manufacturer. Since boards selecting CONFIG_EC_GOOGLE_CHROMEEC_SKUID are the only ones overriding the default mainboard manufacturer, they are the only ones which need this correction. Test: build/boot google/bloog with Linux 5.16, verify SOF drivers correctly detect device as a Chromebook and load the appropriate audio firmware.

A recent Coverity scan found an issue with the way the EC_HOST_EVENT_MASK macro was being used. It was being passed values between 0 and 63, but since it is doing basically (1ULL << (value - 1)), this caused a shift of -1 when `i` is 0 and also doesn't reach the 63rd bit of the mask. This is fixed by incrementing the start and end conditions of the loop by 1, so the event mask ranges from bits 0 to 63, instead of -1 to 62.
