Subject: [PATCH v6 00/15] Support ROHM BD71828 PMIC
Patch series introducing support for ROHM BD71828 PMIC
ROHM BD71828 is a power management IC containing 7 bucks and 7 LDOs. 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.
This patch series is based on v5.5-rc1
