This series adds support for the regulators found in MT6331 and MT6332 main/companion PMICs. Adding support to each driver in each subsystem is done in different patch series as to avoid spamming uninteresting patches to maintainers. Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone. Changes in v4: - Rebased on next-20220912 Changes in v3: - Sorry, one of the commits picked both the pre-rename file and the new one... the v3 fixes the mt6332 bindings commit. - Changed comment style on top for mt633[12]-regulator.c as suggested (missed that in v2) Changes in v2: - Refactored description in dt-bindings - Simplified get_status() function and removed callback where not needed - Simplified set_mode()/get_mode() functions and removed callback where not needed - Added new regulator_ops for no_qi (no .get_status) and for no_ms (no .{get, set}_mode) - Fixed vsel mask on some regulators and removed pattern of repeated voltage entries present in some voltage tables, avoiding to set higher bits for safety - Reordered regulators (and some formatting fixes) in mt6331-regulator.c in per-type alphabetic order AngeloGioacchino Del Regno (4): dt-bindings: regulator: Add bindings for MT6331 regulator regulator: Add driver for MT6331 PMIC regulators dt-bindings: regulator: Add bindings for MT6332 regulator regulator: Add driver for MT6332 PMIC regulators .../regulator/mediatek,mt6331-regulator.yaml | 273 ++++++++++ .../regulator/mediatek,mt6332-regulator.yaml | 112 ++++ drivers/regulator/Kconfig | 18 + drivers/regulator/Makefile | 2 + drivers/regulator/mt6331-regulator.c | 507 ++++++++++++++++++ drivers/regulator/mt6332-regulator.c | 422 +++++++++++++++ include/linux/regulator/mt6331-regulator.h | 46 ++ include/linux/regulator/mt6332-regulator.h | 27 + 8 files changed, 1407 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/mediatek,mt6331-regulator.yaml create mode 100644 Documentation/devicetree/bindings/regulator/mediatek,mt6332-regulator.yaml create mode 100644 drivers/regulator/mt6331-regulator.c create mode 100644 drivers/regulator/mt6332-regulator.c create mode 100644 include/linux/regulator/mt6331-regulator.h create mode 100644 include/linux/regulator/mt6332-regulator.h
