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 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 | 1171 +++++++++++++++++ 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 | 246 ++++ lib/test_linear_ranges.c | 228 ++++ 62 files changed, 3258 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: 16fbf79b0f83 ("Linux 5.6-rc7")
