Add function to read any PPS register based on the intel_dsc_pps enum provided. Add a function which will call the new pps read function and place it in crtc state. Only PPS0 and PPS1 are readout the rest of the registers will be read in upcoming patches. --v2 -Changes in read function as PPS enum is removed -Initialize pps_val as 0 in pps_read func itself [Jani] -Create a function that gets the required register and call that in the common read function [Jani] -Move the drm_WARN_ON one abstraction layer above [Jani] --v3 -Send both reg values regardless of dsc engine no [Jani] -Don't use num_vdsc_instances stick to dsc_split field [Ankit] --v4 -Manipulate the reg values instead of creating MACRO to change name of pps [Ankit] --v5 -Read dsc reg values using array rather than individual variables [Ankit] -Loop the verification of all dsc engine reads to future proof it [Ankit] -Keep the fix me comment in this patch and remove it in later one where we add other readouts [Ankit] -Add switch statement that fills in the required registers based on no of vdsc engines per pipe. --v7 -Pass no of vdsc instances from read_reg function [Ankit] -Fix issue where arrays do not get freed on return for read_and_verify func [Ankit] --v8 -Simplify reading and verifying of register and remove dynamically allocated arrays [Jani] -Remove no_ from no_vdsc_per_pipe and wherever else it applies [Ankit] --v9 -change variable name to dsc_reg_size rather than vdsc_per_pipe [Ankit] --v10 -remove switch case as we never enter case1 [Ankit] --v11 -Add _ prefix for register that are not supposed to be used directly [Jani] -Remove REG suffix from register macros [Jani] -Do not duplicate register read [Jani] --v12 -Use vdsc_per_pipe rather than array size of dsc_reg [Jani] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Animesh Manna <animesh.manna@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230828054300.560559-5-suraj.kandpal@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.
