Systems which do not support RTC run into boot problems as the kernel assumes the availability of the RTC by default. On device tree configured systems the availability of the RTC can be detected by querying the corresponding device tree node. Implement a wallclock init function to query the device tree and disable RTC if the RTC is marked as not available in the corresponding node. [ tglx: Rewrote changelog and comments. Added proper __init(const) annotations. ] Suggested-by: Andy Shevchenko <andriy.shevchenko@intel.com> Signed-off-by: Rahul Tanwar <rahul.tanwar@linux.intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lkml.kernel.org/r/b84d9152ce0c1c09896ff4987e691a0715cb02df.1570693058.git.rahul.tanwar@linux.intel.com
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.
