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.
