[PATCH v6 00/15] staging: typec: tcpci: move out of staging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch set attempts to move the tcpci drivers 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 v6:
- Change function name to be typec_find_port_power/data_role for find
  capability, and typec_find_power_role for find one specific power role.
- Fix rt1711h driver move missing.
- Add one patch to improve the error checking in tcpci driver, use IS_ERR()
  instead of PTR_ERR_OR_ZERO().
- Add Rob's Reviewed-by for patch [2/15].
- Misc typos fix.
 
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)

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.
