The i2c touchpad on Dell XPS 9570 and Precision M5530 doesn't work out of box. The touchpad relies on its _INI method to update its _HID value from XXXX0000 to SYNA2393. Also, the _STA relies on value of I2CN to report correct status. Set acpi_gbl_parse_table_as_term_list so the value of I2CN can be correctly set up, and _INI can get run. The ACPI table in this machine is designed to get parsed this way. Also, change the quirk table to a more generic name.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
