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. Current implementation does not support inversely proportional ranges but adding support for that could be helpful. This version of series introduces new battry DT binding entries and adds the parsing in power_supply_get_battery_info(). Changelog v8: Linear ranges - small improvements suggested by Andy Shevchenko, no functional changes Changelog v7: General: - rebased on top of v5.6 bd99954 driver: - fixed bunch of styling issues spotted by Andy Shevchenko - dropped ACPI table as ACPI properties are not supported at this version of driver. - added few acks Changelog v6: generic: - rebased on top of 5.6-rc7. linear ranges: - moved to lib as requested by Greg KH - EXPORT_SYMBOL => EXPORT_SYMBOL_GPL - licence GPL-2.0, not later - added KUnit test for linear ranges 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: Test for linear ranges helpers Patch 5: Rename driver internal struct linear_range from bd70528-power Patch 6: Use linear-ranges helpers in regulator framework and convert regulator drivers to use new linear_range struct. Patch 7: Use linear-ranges helpers in bd70528 driver Patch 8: Parsing of new battery parameters Patch 9: ROHM BD99954 charger IC driver Patch 10: Fix Kconfig help text indentiation for other entries as well. --- Matti Vaittinen (10): dt-bindings: battery: add new battery parameters dt_bindings: ROHM BD99954 Charger lib: add linear ranges helpers lib/test_linear_ranges: add a test for the 'linear_ranges' power: supply: bd70528: rename linear_range to avoid collision regulator: use linear_ranges helper power: supply: bd70528: use linear ranges power: supply: add battery parameters power: supply: Support ROHM bd99954 charger power: supply: Fix Kconfig help text indentiation .../bindings/power/supply/battery.txt | 6 + .../bindings/power/supply/rohm,bd99954.yaml | 155 +++ drivers/power/supply/Kconfig | 34 +- drivers/power/supply/Makefile | 1 + drivers/power/supply/bd70528-charger.c | 140 +- drivers/power/supply/bd99954-charger.c | 1149 +++++++++++++++++ drivers/power/supply/power_supply_core.c | 8 + drivers/regulator/88pg86x.c | 4 +- drivers/regulator/88pm800-regulator.c | 4 +- drivers/regulator/Kconfig | 1 + drivers/regulator/act8865-regulator.c | 4 +- drivers/regulator/act8945a-regulator.c | 2 +- drivers/regulator/arizona-ldo1.c | 2 +- drivers/regulator/arizona-micsupp.c | 4 +- drivers/regulator/as3711-regulator.c | 6 +- drivers/regulator/as3722-regulator.c | 4 +- drivers/regulator/axp20x-regulator.c | 16 +- drivers/regulator/bcm590xx-regulator.c | 8 +- drivers/regulator/bd70528-regulator.c | 8 +- drivers/regulator/bd71828-regulator.c | 10 +- drivers/regulator/bd718x7-regulator.c | 26 +- drivers/regulator/da903x.c | 2 +- drivers/regulator/helpers.c | 130 +- drivers/regulator/hi6421-regulator.c | 4 +- drivers/regulator/lochnagar-regulator.c | 4 +- drivers/regulator/lp873x-regulator.c | 4 +- drivers/regulator/lp87565-regulator.c | 2 +- drivers/regulator/lp8788-buck.c | 2 +- drivers/regulator/max77650-regulator.c | 2 +- drivers/regulator/mcp16502.c | 4 +- drivers/regulator/mp8859.c | 2 +- drivers/regulator/mt6323-regulator.c | 6 +- drivers/regulator/mt6358-regulator.c | 8 +- drivers/regulator/mt6380-regulator.c | 6 +- drivers/regulator/mt6397-regulator.c | 6 +- drivers/regulator/palmas-regulator.c | 4 +- drivers/regulator/qcom-rpmh-regulator.c | 2 +- drivers/regulator/qcom_rpm-regulator.c | 14 +- drivers/regulator/qcom_smd-regulator.c | 70 +- drivers/regulator/rk808-regulator.c | 10 +- drivers/regulator/s2mps11.c | 14 +- drivers/regulator/sky81452-regulator.c | 2 +- drivers/regulator/stpmic1_regulator.c | 18 +- drivers/regulator/tps65086-regulator.c | 10 +- drivers/regulator/tps65217-regulator.c | 4 +- drivers/regulator/tps65218-regulator.c | 6 +- drivers/regulator/tps65912-regulator.c | 4 +- drivers/regulator/twl-regulator.c | 4 +- drivers/regulator/twl6030-regulator.c | 2 +- drivers/regulator/wm831x-dcdc.c | 2 +- drivers/regulator/wm831x-ldo.c | 4 +- drivers/regulator/wm8350-regulator.c | 2 +- drivers/regulator/wm8400-regulator.c | 2 +- include/linux/linear_range.h | 48 + include/linux/power/bd99954-charger.h | 1075 +++++++++++++++ include/linux/power_supply.h | 4 + include/linux/regulator/driver.h | 27 +- lib/Kconfig | 3 + lib/Kconfig.debug | 11 + lib/Makefile | 2 + lib/linear_ranges.c | 241 ++++ lib/test_linear_ranges.c | 228 ++++ 62 files changed, 3231 insertions(+), 356 deletions(-) create mode 100644 Documentation/devicetree/bindings/power/supply/rohm,bd99954.yaml create mode 100644 drivers/power/supply/bd99954-charger.c create mode 100644 include/linux/linear_range.h create mode 100644 include/linux/power/bd99954-charger.h create mode 100644 lib/linear_ranges.c create mode 100644 lib/test_linear_ranges.c base-commit: 7111951b8d49 ("Linux 5.6")
