This adds the PM8921 XOADC node to the PM8921 PMIC node, defines the channels and further also define an IIO HWMON node for the channels that are used for housekeeping of voltages and die temperature for the PMIC chip die. Tested on the Nexus 7 tablet: lsiio Device 000: PM8921-XOADC cd /sys/bus/iio/devices/iio:device0 cat in_voltage10_input 616461 (0.625V reference voltage) cat in_voltage11_input (1.25V reference voltage) cat temp1_input 35852 (die temperature) Cc: John Stultz <john.stultz@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
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.
