[PATCH v4 0/5] Qualcomm labibb regulator driver

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

 



This series adds a driver for LAB/IBB regulators found on some Qualcomm SoCs.
These regulators provide positive and/or negative boost power supplies
for LCD/LED display panels connected to the SoC.

This series adds the support for pmi8998 PMIC found in SDM845 family of SoCs.

Changes from v3:
- Handled review comments from v3
- In core, swapped the meaning of enable_time and poll_enabled_time; so we
   wait for total enable_time delay, and poll in-between at poll_enabled_time
   interval now.
- fixed dt_bindings_check issues in dt-bindings patch.
- Cleanup of register_labibb_regulator(), and adapted to updated meaning of
   poll_enabled_time.

Changes from v2:
- Review comments from v2
- Moved the poll-to-check-enabled functionality to regulator core.
- Used more core features to simplify enable/disable functions.
- Moved the devicetree binding to yaml.
- Updated interrupt-names and simplified handling.

Changes from v1:
- Incorporated review comments from v1
- Changed from virtual-regulator based handling to individual regulator based
  handling.
- Reworked the core to merge most of enable/disable functions, combine the
  regulator_ops into one and allow for future variations.
- is_enabled() is now _really_ is_enabled()
- Simplified the SC interrupt handling - use regmap_read_poll_timeout,
  REGULATOR_EVENT_OVER_CURRENT handling and notification to clients.
