Imre Deak 8cba903992 drm/i915/tgl: Fix Combo PHY DPLL fractional divider for 38.4MHz ref clock
commit 0e2497e334de42dbaaee8e325241b5b5b34ede7e upstream.

Apply Display WA #22010492432 for combo PHY PLLs too. This should fix a
problem where the PLL output frequency is slightly off with the current
PLL fractional divider value.

I haven't seen an actual case where this causes a problem, but let's
follow the spec. It's also needed on some EHL platforms, but for that we
also need a way to distinguish the affected EHL SKUs, so I leave that
for a follow-up.

v2:
- Apply the WA at one place when calculating the PLL dividers from the
  frequency and the frequency from the dividers for all the combo PLL
  use cases (DP, HDMI, TBT). (Ville)

README

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.
