This patch series extends the driver to also support bq24250/bq24251. The bq24250/251/257 devices have a very similar feature set and are virtually identical from a control register point of view so it made sense to extend the existing driver rather than submitting a new driver. In addition to the new device support the driver is also extended to allow access to some device features previously hidden. Basic and potentially dangerous charger config parameters affecting the actual charging of the Li-Ion battery are only configurable through firmware rather than sysfs properties. However some newly introduced properties are exposed through sysfs properties as access to them may be desired from userspace. For example, it is now possible to manually configure the maximum current drawn from the input source to accommodate different chargers (0.5A, 1.5A, 2.0A and so on) based on system knowledge a userspace application may have rather than rely on the auto-detection mechanism that may not work in all possible scenarios. Note that most patches have dependencies on other patches in the series. v2: - Aligned DT bindings better with existing "ti,*" charger bindings - Dropped patch that improperly reported a missing battery as a dead battery - Fixed (hopefully, that is -- still waiting for my test platform) issue with how the private ACPI driver_data used to identify which bq2425x device to use - Removed boolean DT/ACPI properties mostly by replacing them with more intelligent handling in the driver - Rework/clarification of DT bindings doc - Renamed/refactored filenames/symbols from bq24257 to bq2425x to better reflect that multiple devices are covered. Despite initial hesitation I feel this is a good opportunity for some clean-up as the driver is still very new in the Kernel so the change should be low risk. This also addresses one of Andrew Davis' feedback items. Plus, it makes for a nice alignment with the existing bq2415x_charger driver. v1: - Initial submission Andreas Dannenberg (13): power: bq24257: Add bit definition for temp sense enable power: bq24257: Add basic support for bq24250/bq24251 power: bq24257: Allow manual setting of input current limit power: bq24257: Add SW-based approach for Power Good determination power: bq24257: Add over voltage protection setting support power: bq24257: Add input DPM voltage threshold setting support power: bq24257: Extend scope of mutex protection power: bq24257: Add charge type setting support power: bq24257: Allow input current limit sysfs access power: bq24257: Add various device-specific sysfs properties power: bq24257: Add platform data based initialization power: bq24257: Renaming for consistency dt: power: bq2425x-charger: Cover additional devices .../devicetree/bindings/power/bq24257.txt | 21 - .../devicetree/bindings/power/bq2425x.txt | 70 + drivers/power/Kconfig | 7 +- drivers/power/Makefile | 2 +- drivers/power/bq24257_charger.c | 858 ------------ drivers/power/bq2425x_charger.c | 1404 ++++++++++++++++++++ include/linux/power/bq2425x_charger.h | 30 + 7 files changed, 1509 insertions(+), 883 deletions(-) delete mode 100644 Documentation/devicetree/bindings/power/bq24257.txt create mode 100644 Documentation/devicetree/bindings/power/bq2425x.txt delete mode 100644 drivers/power/bq24257_charger.c create mode 100644 drivers/power/bq2425x_charger.c create mode 100644 include/linux/power/bq2425x_charger.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
