This patch series adds support for RTQ2208 SubPMIC regulators. The RTQ2208 is a multi-phase, programmable power management IC that integrate with dual multi-configurable, synchronous buck converters and two ldos. The bucks features wide output voltage range from 0.4V to 2.05V and the capability to configure the corresponding power stages. Thank you, Alina yu --- Change in v7: - In Patch 2/2: - Include missing <linux/mod_devicetable.h> - Remove fixed_uV in self-defined structure and rtq2208_ldo_get_voltage - Modify sizeof() parameter in rdesc = devm_kzalloc(..., sizeof().....) - Add const to type casting in regulator_ops to avoid unexpected manipulation - Remove rtq2208_of_parse_cb and use of_regulator_match to get constraints.min_uV - Return devm_request_threaded_irq directly - Remove __maybe_unused and redundant comma in rtq2208_device_tables - Remove v2 in MODULE_LICENSE Change in v6: - In Patch 1/2: - Add "additionalProperties: false" to regulator node - In Patch 2/2: - Remove Reported-by tag Change in v5: - In Patch 1/2: - Revise filename from $id - Remove "regulator-compatible" for ldos - Add missing "high" for "richtek,mtp-sel-high" - Remove "regulator-mode" property - Add and modify "unevaluatedProperties: false" and "additionalProperties: false" - Remove "richtek,fixed-uV" - Remove redundant space in "buck-a" and "ldo2" - In Patch 2/2: - Modify 'rdesc->fixed_uV' get, becasue "richtek,fixed-uV" is removed from yaml - Modify 'mtp_sel' get because read property is changed from "richtek,mtp-sel" to "richtek,mtp-sel-high" in yaml - Add missing regulators_node points to regulator node in yaml - Include <linux/bitfield.h> for 'FIELD_PREP' reported by kernel test robot Change in v4: - In Patch 1/2: - Modify filename to "richtek,rtq2208" - Add more desciptions for "regulator-allowed-modes" Change in v3: - In Patch 1/2: - Fix some typos - Modify the descriptions for "richtek,mtp-sel" - Modify the node name to lowercase and remove underscore - Remove '|' from description - Remove "regulator-compatible" from property - Remove "regulator-state-mem" from pattern - Modify node name to generic one --- Alina Yu (2): regulator: dt-bindings: rtq2208: Add Richtek RTQ2208 SubPMIC regulator: rtq2208: Add Richtek RTQ2208 SubPMIC driver .../bindings/regulator/richtek,rtq2208.yaml | 197 +++++++ drivers/regulator/Kconfig | 11 + drivers/regulator/Makefile | 1 + drivers/regulator/rtq2208-regulator.c | 583 +++++++++++++++++++++ 4 files changed, 792 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/richtek,rtq2208.yaml create mode 100644 drivers/regulator/rtq2208-regulator.c -- 2.7.4
