Subject: [PATCH v3 0/5] Qualcomm labibb regulator driver
Date: Thu, 28 May 2020 21:16:20 +0530	[thread overview]
Message-ID: <20200528154625.17742-1-sumit.semwal@linaro.org> (raw)

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 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.
