Subject: [PATCH v5 0/9] Support ROHM BD99954 charger IC
Support ROHM BD99954 Battery Management IC
ROHM BD99954 is a Battery Management IC for 1-4 cell Lithium-Ion
secondary battery. BD99954 is intended to be used in space-constraint
equipment such as Low profile Notebook PC, Tablets and other
applications.
Series extracts a "linear ranges" helper out of the regulator
framework. Linear ranges helper is intended to help converting
real-world values to register values when conversion is linear. I
suspect this is useful also for power subsystem and possibly for clk.
This version of series introduces new battry DT binding entries and
adds the parsing in power_supply_get_battery_info().
Changelog v5:
generic:
- rebased on top of 5.6-rc6.
DT-bindings:
- Dropped -charger extension from compatible and removed wildcard x.
regulators:
- squashed the regulator changes in one patch.
power-supply KConfig:
- fixed indentiation
- dropped unnecessary 'default N' from BD99954.
Changelog v4:
generic:
- rebase and drop RFC.
DT-bindings:
- add I2C node address-cells and size-cells to fix yaml check errors
- uncomment multipleOf:
bd70528:
- add patch which renames driver internal linear_range struct to
avoid collision when regulator/driver.h (which gets included from
rohm generic header) introduces the linear_range struct.
regulators:
- rebase to v5.6-rc2 and convert also the two newly introduced
drivers to use linear_range struct instead of
regulator_linear_range.
linear_ranges:
- Fix kerneldoc.
Changelog RFC-v3:
DT-bindings:
- fix the BD99954 binding (the *-microvolt Vs. *-microvolts issue is
still there. Not sure which one is correct)
- renabe tricklecharge-* binding to trickle-charge-* as suggested by
Rob.
- drop the linear-ranges helper which was written for BD70528 and
extract the linear-range code from regulator framework instead.
- refactor regulator framework to utilize extracted linear-ranges
code.
- change the struct regulator_linear_range to linear_range from
regulator drivers.
- refactor BD70528 to use regulator framework originated
linear-ranges code.
- change BD99954 to use linear-ranges code from regulator framework
Changelog RFC-v2:
DT-bindings:
- Used the battery parameters described in battery.txt
- Added few new parameters to battery.txt
- Added ASCII art charging profile chart for BD99954 to explain
states and limits.
Linear ranges:
- Fixed division by zero error from linear-ranges code if step 0 is
used.
Power-supply core:
- Added parsing of new battery parameters.
BD99954 driver:
- converted to use battery parameters from battery node
- Added step 0 ranges for reg values which do not change voltage
- added dt-node to psy-config
Patch 1:
DT binding docs for the new battery parameters
Patch 2:
BD99954 charger DT binding docs
Patch 3:
Linear ranges helpers
Patch 4:
Rename driver internal struct linear_range from bd70528-power
Patch 5:
Use linear-ranges helpers in regulator framework and
convert regulator drivers to use new linear_range struct.
Patch 6:
Use linear-ranges helpers in bd70528 driver
Patch 7:
Parsing of new battery parameters
Patch 8:
ROHM BD99954 charger IC driver
Patch 9:
Fix Kconfig help text indentiation for other entries as well.
