On JZ4770 and JZ4780, the CLK32K pin is configurable. By default, it is configured as a GPIO in input mode, and its value can be read through GPIO PD14. With this change, clients can now request the 32 kHz clock on the CLK32K pin, through Device Tree. This clock is simply a pass-through of the input oscillator's clock with enable/disable operations. This will permit the WiFi/Bluetooth chip to work on the MIPS CI20 board, which does source one of its clocks from the CLK32K pin.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
