All regulators can be controlled individually via I2C. Bucks 1,2,6 and 7 can also be assigned to a "regulator group" controlled by run-levels. Eg. Run level specific voltages and enable/disable statuses for each of these bucks can be set via register interface. The buck run-level group assignment (selection if buck is to be controlled individually or via run-levels) can be changed at run-time via I2C. This patch series brings only the basic support for controlling regulators individually via I2C. In addition to the bucks and LDOs there are: - The usual clk gate - 4 IO pins (mostly usable as GPO or tied to specific purpose) - power button support - RTC - two LEDs - battery charger - HALL sensor input This patch series adds support to regulators, clk, RTC, GPIOs and LEDs. Power-supply driver for charger is not included in this series. The series also adds LED DT-node lookup based on node name or given property name/value pair in LED core. It also adds generic default-state and default-trigger property handling to LED core. Follow-up patches simplifying few other LED drivers should follow. In GPIO framework this series adds devm-support for gpio_array getting for MFD sub-devices whose GPIO consumer information may be in parent device's DT node. And while I was at it I also added few missing GPIO devm functions to the documentaton listing. Changelog v6: Rebased on top of v5.5-rc1 LED core: - Do new fw-node look-up only if the new match data is given. That way behaviour for existing drivers is not changed - Handle generic LED properties by core only if explisitly requested in init-data. That way behaviour for existing drivers is not changed until they are verified to work. BD71828 LEDs: - Fix module loading by adding "dummy" of_device_id table. DT bindings: All: - Remove regulator run-level properties as run-level support was dropped for now. - Change SPDX to dual lisence LED: - added select: false - replace oneOf + const by enum Regulator: - remove forgotten comments - comment indenting MFD: - remove unnecessary descriptions Regulators: - Dropped patch 12 with run-level controls - Dropped unnecessary ramp_delay_supported() - ram_delay ops were already only filled for DVS bucks. GPIO: - rename internal function. RTC: - Added missing blank line Changelog v5: Only LED patch (patch 15) changed, rest as in v4. LED: - Fixed issues reported by Dan Carpenter and kbuild-bot static analysis. Changelog v4 (first non RFC): General: - Changed subdevice loading and chip version identification to use platform ID. - License identifiers changed to GPL-2.0-only MFD: - Styling fixes mostly DT-Bindings: - a few more checks as suggested by Rob Herring. - Order of DT patches changed. - me as maintainer - standard units to new properties (microvolts, ohms) - runlevel values in an array LED: - BD71828 driver added (back) - Added DT support - Added LED DT node lookup in led framework when init_data is given with DT node match information. - Added common property parsing for default-state and default-trigger. Regulators: - dropped sysfs interfaces - fixed module unload/reload by binding gpio consumer information to regulator device not to MFD. GPIO: - Added devm_gpiod_get_parent_array - added few missing devm functions to documentation Changelog v3: DT-Bindings: - yamlify - add LED binding doc CLK: - Move clk register definitions from MFD headers to clk driver GPIO: - Add generic direction define and use it. LED: - Drop LED driver from the series (for now). Changelog v2: Mainly RTC and GPIO fixes suggested by Alexandre and Bartosz General: -Patch ordering changed to provide dt binding documents right after the MFD core. DT-Bindings for regulators (Patch 3) -Fix typo in PMIC model number RTC (patch 11) -Reverted renaming in order to reduce patch size. -Reworded commit message BD71828 regulator (patch 7) -Add MODULE_ALIAS GPIO (patch 12) -Remove file-name from comment -prefix IN and OUT defines with chip type -improved documentation for the INPUT only pin. -removed empty left-over function -removed unnecessary #ifdef CONFIG_OF_GPIO -removed unnecessary error print -Add MODULE_ALIAS Patch 1: dt-bindings for regulators on BD71828 PMIC Patch 2: dt-bindings for LEDs on BD71828 PMIC Patch 3: dt-bindings for BD71828 PMIC Patch 4: Convert rohm PMICs with common sub-devices to use platform_ device_id to match MFD sub-devices Patch 5: BD71828 MFD core. Patch 6: Power button support using GPIO keys. Patch 7: CLK gate support using existing clk-bd718x7 Patch 8: Split existing bd718x7 regulator driver to generic ROHM dt parsing portion (used by more than one ROHM drivers) and bd718x8 specific parts Patch 9: Basic regulator support (individual control via I2C). This should be pretty standard stuff. Patch 10: Add devm_gpiod_get_parent_array Patch 11: Add missing managed GPIO array get functions to documentation Patch 12: Support BD71828 RTC block using BD70528 RTC driver Patch 13: Allow control of GP(I)O pins on BD71828 via GPIO subsystem Patch 14: Add LED node lookup and common LED binding parsing support to LED class/core Patch 15: Support toggling the LEDs on BD71828.
