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. Changelog v8: LEDs: - Fixed bunch of typos. - Corrected the commit message which errorneously contained the 'leds-compatible' which I dropped in favour of match_property. - use max_brightness instead of LED_FULL if it is given when handling the default_state, "on". - clean fwnode_owned at the end of unsuccessfull registration or at the end of deregistration. - fix the accidental linuxdoc comment. - rename led_find_fwnode to led_get_fwnode as it increases refcount. Changelog v7: - Rebased on top of v5.5-rc2 - Dropped already applied patches - basic regulator support (in regulator tree now) - regulator dt-bindings (in regulator tree now) - gpio devm function documentation (in GPIO tree now) - Dropped new devm-variant of gpio_array getting for MFD sub-devices who have consumer information in parent DT node as gpio consumer was dropped from the series - removed extra line-breaks from MFD driver and Makefile - fixed RTC patch subject line (added missing colon) - included a patch which adds compatible for ROHM BD71850 PMIC 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 LEDs on BD71828 PMIC Patch 2: dt-bindings for BD71828 PMIC Patch 3: Convert rohm PMICs with common sub-devices to use platform_ device_id to match MFD sub-devices Patch 4: Add compatible for BD71850 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: Support BD71828 RTC block using BD70528 RTC driver Patch 10: Allow control of GP(I)O pins on BD71828 via GPIO subsystem Patch 11: Add LED node lookup and common LED binding parsing support to LED class/core Patch 12: Support toggling the LEDs on BD71828. --- Matti Vaittinen (12): dt-bindings: leds: ROHM BD71282 PMIC LED driver dt-bindings: mfd: Document ROHM BD71828 bindings mfd: rohm PMICs - use platform_device_id to match MFD sub-devices mfd: bd718x7: Add compatible for BD71850 mfd: bd71828: Support ROHM BD71828 PMIC - core mfd: input: bd71828: Add power-key support clk: bd718x7: Support ROHM BD71828 clk block regulator: bd718x7: Split driver to common and bd718x7 specific parts rtc: bd70528: add BD71828 support gpio: bd71828: Initial support for ROHM BD71828 PMIC GPIOs leds: Add common LED binding parsing support to LED class/core led: bd71828: Support LED outputs on ROHM BD71828 PMIC .../bindings/leds/rohm,bd71828-leds.yaml | 52 +++ .../bindings/mfd/rohm,bd71828-pmic.yaml | 193 ++++++++ drivers/clk/Kconfig | 6 +- drivers/clk/clk-bd718x7.c | 50 ++- drivers/gpio/Kconfig | 12 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-bd71828.c | 159 +++++++ drivers/leds/Kconfig | 10 + drivers/leds/Makefile | 1 + drivers/leds/led-class.c | 115 ++++- drivers/leds/led-core.c | 258 +++++++++-- drivers/leds/leds-bd71828.c | 118 +++++ drivers/mfd/Kconfig | 15 + drivers/mfd/Makefile | 1 + drivers/mfd/rohm-bd70528.c | 3 +- drivers/mfd/rohm-bd71828.c | 344 ++++++++++++++ drivers/mfd/rohm-bd718x7.c | 43 +- drivers/regulator/Kconfig | 4 + drivers/regulator/Makefile | 1 + drivers/regulator/bd718x7-regulator.c | 200 +++------ drivers/regulator/rohm-regulator.c | 95 ++++ drivers/rtc/Kconfig | 3 +- drivers/rtc/rtc-bd70528.c | 168 ++++++- include/linux/leds.h | 94 +++- include/linux/mfd/rohm-bd70528.h | 19 +- include/linux/mfd/rohm-bd71828.h | 423 ++++++++++++++++++ include/linux/mfd/rohm-bd718x7.h | 6 - include/linux/mfd/rohm-generic.h | 48 +- include/linux/mfd/rohm-shared.h | 27 ++ 29 files changed, 2206 insertions(+), 263 deletions(-) create mode 100644 Documentation/devicetree/bindings/leds/rohm,bd71828-leds.yaml create mode 100644 Documentation/devicetree/bindings/mfd/rohm,bd71828-pmic.yaml create mode 100644 drivers/gpio/gpio-bd71828.c create mode 100644 drivers/leds/leds-bd71828.c create mode 100644 drivers/mfd/rohm-bd71828.c create mode 100644 drivers/regulator/rohm-regulator.c create mode 100644 include/linux/mfd/rohm-bd71828.h create mode 100644 include/linux/mfd/rohm-shared.h base-commit: commit d1eef1c61974 ("Linux 5.5-rc2") -- 2.21.0 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
