The series is organized as follows: - Patch 1 adds the new variant to the existing DT binding, including the changes in electrical characteristics - Patches 2-4 are minor cleanups to the existing BQ25703A OTG regulator driver, slimming down the code and making it more reusable for the new BQ25792 variant - Patch 5 is a logical fix to the BQ25703A clamping logic for VSYSMIN (this is a standalone fix which can be applied independently and may be backported to stable) - Patches 6-8 are slight refactoring of the existing BQ25703A charger driver to make it more reusable for the new BQ25792 variant - Patch 9 adds platform data to distinguish between the two variants in the parent MFD driver, and binds it to the new compatible string - Patches 10-11 add variant-specific code to support the new BQ25792 variant in the regulator part and the charger part respectively, selected by the platform data added in patch 9 Signed-off-by: Alexey Charkov --- Changes in v2: - Fix an error in DT schema (thanks Rob's bot) - Ensure the broadest constraints for all variants remain in the common part of the schema, per writing-schema doc (thanks Krzysztof) - Link to v1: https://lore.kernel.org/r/20260303-bq25792-v1-0-e6e5e0033458@flipper.net --- Alexey Charkov (11): dt-bindings: mfd: ti,bq25703a: Expand to include BQ25792 regulator: bq257xx: Remove reference to the parent MFD's dev regulator: bq257xx: Drop the regulator_dev from the driver data regulator: bq257xx: Make OTG enable GPIO really optional power: supply: bq257xx: Fix VSYSMIN clamping logic power: supply: bq257xx: Make the default current limit a per-chip attribute power: supply: bq257xx: Consistently use indirect get/set helpers power: supply: bq257xx: Add fields for 'charging' and 'overvoltage' states mfd: bq257xx: Add BQ25792 support regulator: bq257xx: Add support for BQ25792 power: supply: bq257xx: Add support for BQ25792 .../devicetree/bindings/mfd/ti,bq25703a.yaml | 73 ++- drivers/mfd/bq257xx.c | 60 ++- drivers/power/supply/bq257xx_charger.c | 534 ++++++++++++++++++++- drivers/regulator/bq257xx-regulator.c | 123 ++++- include/linux/mfd/bq257xx.h | 415 ++++++++++++++++ 5 files changed, 1164 insertions(+), 41 deletions(-) --- base-commit: d517cb8cea012f43b069617fc8179b45404f8018 change-id: 20260303-bq25792-0132ac86846d Best regards, -- Alexey Charkov
