* 88pm860x_battery: Convert to using managed resourcesVaishali Thakkar2015-09-221-26/+11
| | | | | | | | | | | | Use managed resource functions devm_request_threaded_irq and devm_power_supply_register to simplify error handling. To be compatible with the change, various gotos are replaced with direct returns and unneeded labels are dropped. Also, remove pm860x_battery_remove as it is now redundant.

* power:lp8727_charger: parsing child node after getting debounce-msMilo Kim2015-09-221-4/+4
| | | | | | | | | | | | | | | | | According to lp8727 bindings[*], charging parameter is optional. So parsing can be skipped in case those properties are undefined. However, 'debounce-ms' should be read prior to checking the properties. Otherwise, 'debounce-ms' property will be ignored even it is configured inside the DT. So, counting child is processed after updating 'debounce-ms'.

* power:lp8727_charger: use the private data instead of updating I2C device ↵Milo Kim2015-09-221-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | platform data Currently, lp8727 charger driver parses the DT and copies values into the 'cl->dev.platform_data' if 'of_node' exists. This may have architectural issue. Platform data is configurable through the DT or I2C board info inside the platform area. However, lp8727 driver changes this configuration when it is loaded. The driver should get data from the platform side and use the private data, 'lp8727_chg->pdata' instead of changing the original platform data. _probe() procedure is changed as follows. 1. lp8727_parse_dt() returns the pointer of lp8727_platform_data. The driver uses this allocated platform data. So it should keep original platform data, 'dev->platform_data'. 2. In _probe(), check the return value of lp8727_parse_dt(). If an error is found, then exit as PTR_ERR(pdata). 3. If 'of_node' is not found, then the driver just gets the platform data from the I2C device structure. 4. Map the platform data to private data structure.

* power: Add an axp20x-usb-power driverHans de Goede2015-09-223-0/+256
| | | | | | | | | | | | | | | | | | | | | This adds a driver for the usb power_supply bits of the axp20x PMICs. I initially started writing my own driver, before coming aware of Bruno Prémont's excellent earlier RFC with a driver for this. My driver was lacking CURRENT_MAX and VOLTAGE_MIN support Bruno's drvier has, so I've copied the code for those from his driver. Note that the AC-power-supply and battery charger bits will need separate drivers. Each one needs its own devictree child-node so that other devicetree nodes can reference the right power-supply, and thus each one will get its own mfd-cell / platform_device and platform-driver.

Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.

Add a parameter to hfi1_cdev_init which controls if the user should have access to this device which places it in a different class with the appropriate devnode callback. In addition set the devnode call back for the existing class to be a bit more explicit for those permissions.
