This patch set attempts to move the tcpci driver out of staging by fix some tcpci driver issues and define typec and power delivery device properties, the changes are verified on NXP PTN5110, which is a standard tcpci typec port controller device with power delivery support, tested power source and sink with drp config.
Changes for v5: - Use "power-role" and "data-role" for typec port power and data capability property name. - Use macro defintion instead of cryptic numbers for readability of power delivery properties(PDO). - Add one tcpci driver binding string to be "nxp,ptn5110" to follow binding name rule "<vendor prefix>,<device>". - Change operating power property name to be op-sink-microwatt. - Add one patch(remove unused tcpci_tcpc_config) to resolve bisectablitity issue of patch usb: typec: add fwnode to tcpc. - A minor error handling change to keep the error path and success path separate in patch: register port before request irq - Rebase to latest Greg's tree with max_snk_* removed. Changes for v4: - Remove max-sink-* properties as we will purge max_snk_* in tcpm, see patch set[4]. - Get typec power and data type value via name string(patch 5). - Move finding typec and pd properties code from tcpci to tcpm(patch 6) - Add a compatible string for nxp ptn5110 typec controller in tcpci driver. (patch 3) - Add set cc for drp toggling without try.src/snk in tcpm(patch 10), then patch 11 can only update CCx bits for keep disconnect cc line open. - Update op-sink-microwatt-hours example value to be the right value in micorwatts, and accordingly divide 1000 to get its miliwatts value in patch 6. - Add Guenter's Reviewed-by for patch(8/9/12) [4] https://www.spinics.net/lists/linux-usb/msg167261.html Changes for v3: - Use 2 properties to separate power and data capability of typec port: "power-type" and "data-type", this is based on Heikki's typec class code change[2]. use "try-power-role" to present if the typec port can support Try.SNK or Try.SRC. - 4 sink properties(max_sink_mv/ma/mw and op_sink_mw) are kept because the counterpart code is back, see revert patch[3], meanwhile I post a patch to fix the reported problem of current source pdo select machinism(which completely ignored those 4 sink settings), to see if we can keep current code, once it was discussed and have conclusion I can update this accordingly. - Use fwnode to get the connector node for dt setting parse. Main changes for v2: - Typec properties are based on general usb connector bindings[1] proposed by Andrzej Hajda, use the standard unit suffixes as defined in property-units.txt. - Add 2 infra APIs to get power sink and source config from dt. - Don't change the set_cc api, to keep the uncontacted cc line open, set cc1/cc2 to be open in tcpci driver when set polarity. - Directly enable vbus detect in tcpci driver rather than add a API. - Details added in each patch.
