Linux kernel source tree
ce02513012
Based on some comments in dm_pp_display_configuration
above the crtc_index and line_time fields, these values
are programmed to the SMC to work around an SMC hang
when it switches MCLK.
According to Alex, the Windows driver programs them to:
mclk_change_block_cp_min = 200 / line_time
mclk_change_block_cp_max = 100 / line_time
Let's use the same for the sake of consistency.
Previously we used the watermark values, but it seemed buggy
as the code was mixing up low/high and A/B watermarks, and
was not saving a low watermark value on DCE 6, so
mclk_change_block_cp_max would be always zero previously.
Split this change off from the previous si_upload_smc_data
to make it easier to bisect, in case it causes any issues.

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.
