Subject: [PATCH 0/8] usb: typec: ucsi: glink: merge in altmode support
Date: Tue, 16 Apr 2024 05:20:49 +0300 [thread overview]
Message-ID: <20240416-ucsi-glink-altmode-v1-0-890db00877ac@linaro.org> (raw)
PMIC GLINK platforms handle the altmode support via OOB messages rather
than by fully following the UCSI standard. Currently altmode handling is
implemented in a separate driver, which has to duplicate significant
part of the USB-C stack to control USB-C muxes, switches and retimers.
Also this potentially introduces race conditions, since both UCSI and
pmic-glink-altmode will drive those components. Last but not least,
there is no connection betnween the altmode's aux-hpd-bridge and
corresponding typec_port instance.
Merge the pmic-glink-altmode driver into the ucsi-glink, streamling the
altmode support for Qualcomm platforms.
Depends: https://lore.kernel.org/linux-usb/20240411-ucsi-orient-aware-v2-0-d4b1cb22a33f@linaro.org/
Merge strategy: since the series involves both UCSI and soc/qcom
drivers, I'd kindly ask to ack merging the whole patchset through the
USB tree.
