2022-05-13platform/chrome: Add ChromeOS ACPI device driverEnric Balletbo i Serra1-0/+1
The x86 Chromebooks have the ChromeOS ACPI device. This driver attaches to the ChromeOS ACPI device and exports the values reported by ACPI in a sysfs directory. This data isn't present in ACPI tables when read through ACPI tools, hence a driver is needed to do it. The driver gets data from firmware using the ACPI component of the kernel. The ACPI values are presented in string form (numbers as decimal values) or binary blobs, and can be accessed as the contents of the appropriate read only files in the standard ACPI device's sysfs directory tree. This data is consumed by the ChromeOS user space.

2019-07-03docs: extcon: convert it to ReST and move to ACPI dirMauro Carvalho Chehab1-0/+1
The intel-int3496.txt file is a documentation for an ACPI driver. There's no reason to keep it on a separate directory. So, instead of keeping it on some random location, move it to a sub-directory inside the ACPI documentation dir, renaming it to .rst.
