<id>1b0ce903fe747d72e9eab86a06c79fb2c7ba2bab</id>
<content type='text'>
[Why]
Tune settings for improved text display.
Handle differences between DWM and MPO in HDR path.

[How]
Update sharpener LBA table.
Use HDR multiplier to calculate scalar matrix coefficients
 for HDR RGB MPO path.
Update unit tests.

<id>6efc0ab3b05de0d7bab8ec0597214e4788251071</id>
<content type='text'>
[Why]
Addressed previous issues with quality changes and new issues due to
 rolling back quality changes.

[How]
This reverts commit f9e6759888866748f31b6b6c2142a481d587f51f, fixes merge conflicts, and fixed some
 formatting errors.
Store current sharpness level for each pregen table to minimize
 calculating sharpness table every time.
Disable dynamic ODM when sharpness is enabled.

[Why]
Seeing several regressions related to quality EASF and ISHARP changes
and removing dc dependency changes.

[How]
Roll back SPL changes

<content type='text'>
[Why]
Make SPL library dc-independent so it can be reused by other
 components

[How]
Create separate set of fixed31_32 calls in SPL
Make all inputs and outputs to SPL use primitive types
For ratios and inits, return as uint32 from SPL.  So
 add conversion from uint32 back to fixed point in
 SPL-to-dc translate function

[Why]
Update coefficients and LUT tables for scaler and sharpener
 to improve quality and support different use cases (SDR/HDR)

[How]
Move scaler coefficients to new file dc_spl_scl_easf_filters.c
Remove older coefficients file dc_sp_scl_filters_old.c
Update default taps for EASF support
Update LLS policy for DON'T CARE case
Update cositing offset from 0.5 to 0.25
Add support to adjust sharpness based on level, use case,
 and scaling ratio ( using discrete levels )
Apply sharpness to all RGB surfaces and both NV12 and P010
 video ( in fullscreen only ).  Upscale and 1:1 ratios only
Enable scaler when sharpening 1:1 ratios
Add support for coefficients that are in S1.10 format
 (convert to S1.12 format)
