All regulators can either 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. Run level changes can then be initiated wither via I2C writes or GPIO. and when run-level is changed, state of all bucks which are set to be controlled via run-levels are changed accrdingly. This control mechanism selection (I2C or GPIO) is selected by data in one time programmable PMIC memory area (during production) and can't be changed later. 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 "under construction" and 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 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: Add support for getting regulator voltages when run-levels are used. Allow specifying voltages for run-levels via DT and in-kernel API. Support changing run-levels via in-kernel API. Patch 13: Support BD71828 RTC block using BD70528 RTC driver Patch 14: Allow control of GP(I)O pins on BD71828 via GPIO subsystem Patch 15: Add LED node lookup and common LED binding parsing support to LED class/core Patch 16: Support toggling the LEDs on BD71828.
