V2: Guenter Roeck's review - Converts suggested qcom_pmic_tcpm_core.c into one-liners - Adds comment on how polarity is set in set_polarity() - Removes optional set_current_limit() - regmap_read/regmap_write Reviwing other pm8150b/spmi drivers I then added in checks for all reamap_read()/regmap_write() calls. - Fixes (type == TCPC_TX_CABLE_RESET || TCPC_TX_HARD_RESET) thanks I definitely had the blinkers on there and didn't see that at all - qcom_pmic_tcpm_pdphy_pd_transmit_payload() Treats regmap_read and read value as separate error paths - qcom_pmic_tcpm_pdphy_set_pd_rx() Replaces boolean if/else with !on as suggested - Returns -ENODEV not -EINVAL on dev_get_regmap() error - qcom_pmic_tcpm_pdphy_pd_receive() Guenter asks: "No error return ?" bod: No we are inside an ISR here if we read data we pass that off to TCPM if somehow we don't read the data - it is "junk" there's no value IMO in pushing an error upwards back to the handler. 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. Differences between the two can be seen by git diff usb-next-27-10-21-pm8150b-tcpm-v2..usb-next-25-10-21-pm8150b-tcpm -- drivers/usb/typec/tcpm Latest bootable series can be found here: Link: https://git.linaro.org/people/bryan.odonoghue/kernel.git/log/?h=usb-next-27-10-21-pm8150b-tcpm-v2 Previous set: Link: https://lore.kernel.org/all/20211025150906.176686-1-bryan.odonoghue@linaro.org/T/#t V1: This series adds a set of yaml and a driver to bind together the type-c and pdphy silicon in qcom's pm8150b block as a Linux type-c port manager. 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. An additional series will follow this one for the SoC and RB5 dtsi and dts respectively.
