This patch series extends the driver to also support bq24250/bq24251. Most patches have dependencies on other patches in the series but I left them spread out so that one can better understand the change history. However I can certainly fold them together and resubmit if needed. 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. As per offline discussion with Laurentiu the basic and potentially dangerous charger config parameters affecting the actual charging of the Li-Ion battery are still 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. Laurentiu-- I've spent quite some time testing the driver however the one piece I could not test was the ACPI integration due to lack of suitable HW. For this do you think you could give this a quick try? I'm particularly interested if the private driver data from the bq24257_acpi_match[] structure gets properly passed down into bq24257_probe(). Also if you could recommend an embedded HW platform that I could generally use to test ACPI support I'd appreciate that (MinnowBoard MAX?). -- Andreas Dannenberg Texas Instruments Inc Andreas Dannenberg (13): power: bq24257: Add bit definition for temp sense enable power: bq24257: Add dead battery reporting 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 VINDPM voltage threshold setting support power: bq24257: Extend scope of mutex protection power: bq24257: Add charge type setting support power: bq24257: Add in_ilimit setting support power: bq24257: Add various device-specific sysfs properties power: bq24257: Add platform data based initialization dt: power: bq24257-charger: Cover additional devices .../devicetree/bindings/power/bq24257.txt | 59 +- drivers/power/Kconfig | 5 +- drivers/power/bq24257_charger.c | 652 +++++++++++++++++++-- include/linux/power/bq24257_charger.h | 30 + 4 files changed, 677 insertions(+), 69 deletions(-) create mode 100644 include/linux/power/bq24257_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
