[v2,0/4] Qualcomm labibb regulator driver

Message

Sumit Semwal May 8, 2020, 8:41 p.m. UTC

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 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.

Nisha Kumari (4):
  dt-bindings: regulator: Add labibb regulator
  arm64: dts: qcom: pmi8998: Add nodes for LAB and IBB regulators
  regulator: qcom: Add labibb driver
  regulator: qcom: labibb: Add SC interrupt handling
