Introduce intel_cdclk state which for now will track the cdclk frequency, the vco frequency and the reference frequency (not sure we want the last one, but I put it there anyway). We'll also make the .get_cdclk() function fill out this state structure rather than just returning the current cdclk frequency. One immediate benefit is that calling .get_cdclk() will no longer clobber state stored under dev_priv unless ex[plicitly told to do so. Previously it clobbered the vco and reference clocks stored there on some platforms. We'll expand the use of this structure to actually precomputing the state and whatnot later. v2: Constify intel_cdclk_state_compare() v3: Document intel_cdclk_state_compare() v4: Deal with i945gm_get_cdclk() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170207183345.19763-1-ville.syrjala@linux.intel.com |

README
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.
