Hi,
The second version comes with the simplified diff in 1/3.
Because it caused a conflict in 2/3 I'm sending entire
patchest.
The patches are available in the public git branch:
https://github.com/Semihalf/edk2-platforms/commits/utmi-upstream-r20200515
I'm looking forward to the comments and remarks.
Best regards,
Marcin

This patch introduce following modifications, allowing to
overcome the instabilities observed with certain USB2.0 endpoints:
* Add additional step which enables the Impedance and PLL calibration.
* Enable old squelch detector instead of the new analog squelch detector
circuit and update host disconnect threshold value.
* Update LS TX driver strength coarse and fine adjustment values.

According to Design Reference Specification the PHY PLL and Calibration
register from PHY0 are shared for multi-port PHY. PLL control registers
inside other PHY channels are not used.
This fixes issues in scenarios when only UTMI port1 was in use, which
resulted with lack of correct PLL initialization. On the occasion
add relevant comments, describing the register groups in the header
file.

If UTMI connected to USB Device, the MUX must be configured
prior to the PHY init. Add missing register update in the
relevant code.

I'm OK with the current version of the code, but just noticed this.
No one can give Signed-off-by for another.
If Grzegorz is the author, that should be noted in a From: tag. Git
format-patch does this automatically if the commit's Author metadata
is set.
This applies to all 3 patches.

The 3/3 has only only my signed-off tag (and my authorship).
Regarding the first 2, I did the actual change, but it was based on
the original U-Boot patch from Grzegorz. How about, instead of the tag,
I give him a credit in a following way:
Based on the original U-Boot patch from Grzegorz Jaszczyk <jaz@semihalf.com>
Would that work for you?

Marcin

OK, I admit it, I was lazy and spotted this and only checked 2/3 and
assumed it was all of them :)

I have no objections to that as such, but perhaps a link to the patch
posting in an email archive, or the commit in a git repo, would be
more generically useful.
