| * charger-manager: Modify the way of checking battery's temperatureJonghwa Lee2013-12-242-49/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Charger-manager driver used to check battery temperature through the callback function passed by platform data. Unfortunatley, without that pre-defined callback function, charger-manager can't get battery's temperature at all. Also passing callback function through platform data ruins DT support for charger-manager. This patch mondifies charger-manager driver to get temperature of battery without pre-defined callback function. Now, charger-manager can use either of battery thermometer in fuel-gauge and ouside of battery. It uses thermal framework interface for outer thermometer if thermal fw is enabled. Otherwise, it tries to use fuel-gauge's through the power supply interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a notifier chain to the power_supply, this helps drivers in other subsystem to listen to changes in power supply subsystem. This would help to take some actions in those drivers on changing the power supply properties. One such scenario is to increase/decrease system performance based on the battery capacity/voltage. Another scenario is to adjust the h/w peak current detection voltage/current thresholds based on battery voltage/capacity. The notifier helps drivers to listen to changes in power_suppy susbystem without polling the power_supply properties Signed-off-by: Jenny TC <jenny.tc@intel.com> Signed-off-by: Pali Rohár <pali.rohar@gmail.com> Acked-by: Jenny TC <jenny.tc@intel.com> Signed-off-by: Anton Vorontsov <anton@enomsg.org>

This leaves .of_node unset in many cases. When this happens, entries in the DT /aliases property which refer to the top-level MFD DT node will never match the MFD child devices, hence causing the requested alias not to be honored. Solve this by setting each MFD child device's .of_node equal to the top- level MFD device's .of_node field in the cases where it would otherwise remain unset. The first use-case for this will be aliases for the TPS6586x's RTC device. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
| * | mfd: cros ec: spi: Add delay for raising CSRhyland Klein2014-01-212-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EC has specific timing it requires. Add support for an optional delay after raising CS to fix timing issues. This is configurable based on a DT property "google,cros-ec-spi-msg-delay". If this property isn't set, then no delay will be added. However, if set it will cause a delay equal to the value passed to it to be inserted at the end of a transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | memset() was being called with the second parameter set to '\0', which is equivalent but longer than the more canonical 0. Update the code to use the latter variant consistently across the driver. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is not used on any non-DT platform, so it can depend on the OF Kconfig symbol to make that explicit. This is in preparation of a subsequent patch which parses some parameters from the device tree and would otherwise have to conditionalize that code.
