This port only provides fn key behavior configuration. Unfortunately, while all this functionality is implemented in ACPI, it's currently not possible to use ACPI to boot Linux on such Qualcomm devices. Thus this series implements and enables a new driver that provides support for the EC features. The EC would be one of the last pieces to get almost full support for the Acer Aspire 1 laptop in the upstream Linux kernel. This series is similar to the EC driver for Lenovo Yoga C630, proposed in [1] but seemingly never followed up...
