The expected orientation-switch path is connector/port@0 <-> phy/port@X <-> dp/port@0 This can then be expanded to connector/port@0 <-> redriver/port@0 <-> phy/port@X <-> dp/port@0 - Rob, Bjorn, Krzysztof - Data role The data-role path is connector/port@0 <-> dwc3/port@Y Previous set: https://lore.kernel.org/linux-arm-msm/20230318121828.739424-1-bryan.odonoghue@linaro.org/ Bootable: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/linux-next-23-04-12-pm8150b-tcpm-qcom-wrapper-typec-mux V4: - Per Rob's input the pdphy and type-c appear as stadalone blocks inside of the PMIC declaration which is a 1:1 mapping of PMIC hardware. The TCPM virtual device is declared at the top-level. https://lore.kernel.org/all/YY7p7jviA3ZG05gL@robh.at.kernel.org/ - Squashes the removal of the old driver with the addition of the new. - Heikki, Gunter https://lore.kernel.org/all/YYVHcHC1Gm92VxEM@kuha.fi.intel.com/ - Reworked Dmitry's old patch for the QMP to account for file renames and very minimal code-drift in the interregnum. - New yaml checks drive update of PMIC VBUS yaml - Some housekeeping on the sc7180 yaml side. sc7180 is not supported yet. - Expands and fixes the examples being added in the PMIC tcpm examples.

Heikki Krogerus' review - Includes Makefile I missed adding to my git index - Removes old Kconfig entry for remove driver Randy Dunlap's review - Rewords drivers/usb/typec/tcpm/Kconfig - Drops tautology "aggregates togther" - Corrects spelling typos BOD's own review - Drops redundant include of regmap.h in qcom_pmic_tcpm_core.c - Propogates qcom_pmic_tcpm_pdphy_disable() error upwards - Propogates pmic_pdphy_reset() error upwards - Drops error prints in qcom_pmic_tcpm_pdphy_pd_transmit_payload() I had these in-place during development and don't recall them being triggered even once, they are redundant, remove.

As part of that we retire the existing qcom-pmic-typec driver and fully replicate its functionality inside of the new block with the additional pdphy stuff along with it.
