Subject: [PATCH 0/3] TBT3/USB4 support for PS8830
Date: Tue, 14 Oct 2025 18:06:44 +0200 [thread overview]
Message-ID: <20251014-topic-ps883x_usb4-v1-0-e6adb1a4296e@oss.qualcomm.com> (raw)
As the product page [1] states, the chip is actually capable of
retiming USB4 and Thunderbolt 3 (4, even!) signals, while remaining
spec-compliant.
This series reworks the driver a little and introduces support for the
new aforementioned modes.
I carried Jack's Reviewed-by tags from an internal preview submission,
which I hope is fine with everyone.
