As of now whenerver HDR is switched on we use the PWM to change the backlight as opposed to AUX based backlight changes in terms of nits. This patch writes to the appropriate DPCD registers to enable aux based backlight using values in nits. --v2 -Fix max_cll and max_fall assignment [Jani] -Fix the size sent in drm_dpcd_write [Jani] --v3 -Content Luminance needs to be sent only for pre-ICL after that it is directly picked up from hdr metadata [Ville] --v4 -Add checks for HDR TCON cap bits [Ville] -Check eotf of hdr_output_data and sets bits base of that value. --v5 -Fix capability check bits. -Check colorspace before setting BT2020 --v6 -Use intel_dp_has_gamut_dip to check if we have capability to send sdp [Ville] -Seprate filling of all hdr tcon related bits into it's own function. -Check eotf data to make sure we are in HDR mode [Sebastian] --v7 -Fix confusion function name for hdr mode check [Jani] -Fix the condition which tells us if we are in HDR mode or not [Sebastian] --v8 -Call fill_hdr_tcon_param unconditionally as some parameters may not be dependent on the fact if we are in hdr mode or not [Sebastian] -Fix some conditions after change in hdr mode check [Sebastian] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Sebastian Wick <sebastian.wick@redhat.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240507040407.1056061-7-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 reStructuredText 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.
