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(). Please note that regulator drivers have been compile tested (but not linked) after patch 5. Please also note that only the BD71847 based regulator testing has been performed after the patch 6 - all testing is highly appreciated. 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: Rename struct regulator_linear_range to struct linear_range and convert regulator drivers to use renamed struct Patch 6: Use linear-ranges helpers in regulator framework Patch 7: Use linear-ranges helpers in bd70528 driver Patch 8: Parsing of new battery parameters Patch 9: ROHM BD99954 charger IC driver --- Matti Vaittinen (9): dt-bindings: battery: add new battery parameters dt_bindings: ROHM BD99954 Charger drivers: base: add linear ranges helpers power: supply: bd70528: rename linear_range to avoid collision regulator: rename regulator_linear_range to linear_range regulator: use linear_ranges helper power: supply: bd70528: use linear ranges power: supply: add battery parameters power: supply: Support ROHM bd99954 charger .../bindings/power/supply/battery.txt | 6 + .../bindings/power/supply/rohm,bd9995x.yaml | 155 +++ drivers/base/Kconfig | 3 + drivers/base/Makefile | 1 + drivers/base/linear_ranges.c | 246 ++++ drivers/power/supply/Kconfig | 11 + 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 +- 60 files changed, 3007 insertions(+), 344 deletions(-) create mode 100644 Documentation/devicetree/bindings/power/supply/rohm,bd9995x.yaml create mode 100644 drivers/base/linear_ranges.c 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 base-commit 11a48a5a18c6 ("Linux 5.6-rc2")
