[PATCH v3 0/4] usb: typec: Add new driver for Parade PS8830 Type-C Retimer

[Abel Vesa]

The Parade PS8830 is a Type-C multi-protocol retimer that is controlled
via I2C. It provides altmode and orientation handling and usually sits
between the Type-C port and the PHY.

It is currently used alongside Qualcomm Snapdragon X Elite SoCs on quite
a few laptops already.

This new driver adds support for the following 3 modes:
 - DP 4lanes (pin assignments C and E)
 - DP 2lanes + USB3 (pin assignment D)
 - USB3

This retimer is a LTTPR (Link-Training Tunable PHY Repeater) which means
it can support link training from source to itself. This means that the
DP driver needs to be aware of the repeater presence and to handle
the link training accordingly. This is currently missing from msm dp
driver, but there is already effort going on to add it. Once done,
full external DP will be working on all X1E laptops that make use of
this retimer.

NOTE: Currently, due to both LTTPR missing support in msm DP and a
reported crash that can happen on DP unplug, the DP DT patch is not
supposed to be merged yet. That patch is only shared for testing purposes.
Once those 2 issues have been resolved, the MDSS DP 0-2 enablement patch
will be respun.

Changes in v3:
- Reworked the schema binding by using the usb/usb-switch.yaml defined
  port graph and properties. Addressed all comments from Johan and
  Dmitry.
- Dropped the manual caching of the config values on regmap write in the
  driver.
- Reordered the DP pin assignment states within the switch clause, as
  Dmitry suggested.
- Added SVID check to not allow any altmode other than DP.
- Added DT patches (retimer for USB orientation handling and DP
  enablement). Did this in order to offer a full picture of how it all
  fits together.
- Split the DP enablement in DT in a separate patchset so the USB
  handling can be merged separately. 
- Added ps8830,boot-on to let the driver know it is supposed to skip
  resetting the retimer on driver probe, as the bootloader might already
  let it in a pre-configured state.
- Marked all retimer voltage regulators as boot-on since we want to
  maintain the state for coldplug orientation.
- Added pinconf for all retimer0 gpios.
- Didn't pick up Konrad's T-b tags and Krzysztof's R-b tag as the rework
  is quite extensive. Especially because of the ps8830,boot-on and what
  it does.
- Link to v2: https://lore.kernel.org/r/20241004-x1e80100-ps8830-v2-0-5cd8008c8c40@linaro.org

Changes in v2:
- Addressed all comments from Johan and Konrad.
- Reworked the handling of the vregs so it would be more cleaner.
  Dropped the usage of bulk regulators API and handled them separately.
  Also discribed all regulators according to data sheet.
- Added all delays according to data sheet.
- Fixed coldplug (on boot) orientation detection.
- Didn't pick Krzysztof's R-b tag because the bindings changed w.r.t
  supplies.
- Link to v1: https://lore.kernel.org/r/20240829-x1e80100-ps8830-v1-0-bcc4790b1d45@linaro.org

[PATCH v3 1/4] dt-bindings: usb: Add Parade PS8830 Type-C retimer bindings

[Abel Vesa]

Document bindings for the Parade PS8830 Type-C retimer. This retimer is
currently found on all boards featuring Qualcomm Snapdragon X Elite SoCs
and it is needed to provide altmode muxing between DP and USB, but also
connector orientation handling between.

[PATCH v3 2/4] usb: typec: Add support for Parade PS8830 Type-C Retimer

[Abel Vesa]

The Parade PS8830 is a Type-C muti-protocol retimer controlled over I2C.
It provides both altmode and orientation handling.

Add a driver with support for the following modes:
 - DP 4lanes
 - DP 2lanes + USB3
 - USB3

[PATCH v3 3/4] arm64: dts: qcom: x1e80100-crd: Add Parade PS8830 related nodes

[Abel Vesa]

Add nodes for all 3 Parade PS8830 Type-C retimers found on Qualcomm
X Elite CRD board, along with all of their voltage regulators. These
retimers sit between the Type-C connectors and the PHYs, so describe the
pmic glink graph accordingly. On this board, these retimers might be left
enabled and configured by the bootloader, so make sure the retimers don't
reset their configuration on driver probe.

Hi,

Couple of nitpicks.

The prefix here should be the vendor, not the model. How come whether or
not it is enabled at boot cannot be detected at runtime?

It would be nice if there was a hint here about how this statement
manifest itself in the patch.


Hint:
https://docs.kernel.org/process/submitting-patches.html#describe-your-changes
is a good read for how to structure ones commit message - with a problem
description, then a technical description of the change (i.e. probably
not something starting with the word "Add"...)

This sentence ends a bit weird to me, please polish it (although
preferably, rewrite it according to "describe your changes")

Don't know if the guidelines has changed on this, but for a single clock
we used to omit clock-names, as it doesn't add any/much value.

Re: [PATCH v3 4/4] arm64: dts: qcom: x1e80100-crd: Enable external DP

Please document why you're forcing 2 data lanes for each DP (should this
restriction remain when we add support for 4 lanes?) - and I would be
extra happy if you spelled out your abbreviations.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
