Add changes to configure port clock registers for ADL-S. Combo phy port clocks are configured by DPCLKA_CFGCR0 and DPCLKA_CFGCR1 registers. The DDI to internal clock mappings in DPCLKA_CFGCR0 register for ADL-S translates to DDI A -> DDIA DDI B -> USBC1 DDI I -> USBC2 For DPCLKA_CFGCR1 DDI J -> USBC3 DDI K -> USBC4 Bspec: 50287 Bspec: 53812 Bspec: 53723 v2: Replace I915_READ() with intel_de_read().(Jani) v3: - Use reg variable to assign ADLS specific registers inorder to replace branching with intel_de_read/write() calls.(mdroper) - Reuse icl_get_ddi_pll() for ADLS to fix issue with updating active dpll on driver load.(aswarup) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Aditya Swarup <aditya.swarup@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210125140753.347998-7-aditya.swarup@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.
