* power/smb347-charger.c: set IRQF_ONESHOT flag to ensure IRQ requestValentin Rothberg2015-03-021-1/+2
| | | | | | | | | | | Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request may fail.

* power: remove use of __devexit_pBill Pemberton2012-11-281-1/+1
| | | | | | | | | | | CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer needed.

* smb347-charger: Fix battery status reporting logic for charger faultsRamakrishna Pallala2012-09-201-15/+82
| | | | | | | | | | | | | This patch checks for charger status register for determining the battery charging status and reports Discharing/Charging/Not Charging/Full accordingly. This patch also adds the interrupt support for Safety Timer Expiration. This interrupt is helpful in debugging the cause for charger fault.

* smb347-charger: Clean up battery attributesRamakrishna Pallala2012-05-061-49/+0
| | | | | | | | | | | | | | | | | CURRENT_NOW and VOLTAGE_NOW should be instantaneous readings from power supply(ex: battery). smb347 charger driver reports charge voltage for VOLTAGE_NOW and charge current for CURRENT_NOW attributes which are not instantaneous readings. This patch removes the battery VOLTAGE_NOW and CURRENT_NOW properties from the driver and also removes hw_to_current() which is not required anymore.

* smb347-charger: Convert to regmap APIMika Westerberg2012-05-051-327/+231
| | | | | | | | | | | | The smb347-charger driver does a lot of read-modify-write to the device registers. Instead of open-coding everything we can take advantage of regmap API which provides nice functions to do this kind of things. In addition there is no need for custom debugfs file for dumping registers as this is already provided by the regmap API.

* smb347-charger: Move IRQ enabling to the end of probeMika Westerberg2012-05-051-4/+2
| | | | | | | | | | | | | | | There is a potential problem if we call smb347_irq_enable() from smb347_irq_init() because smb347_irq_enable() makes the device registers read-only once it returns and smb347_irq_init() expects them to still be read-write. Currently no harm happens because it is the last call we make in smb347_irq_init(). Anyway a better place for enabling IRQs is at the end of probe function and this is also symmetric to call smb347_irq_disable() which is done at the beginning of remove function.

* smb347-charger: Rename few functions to match better what they are doingMika Westerberg2012-05-051-21/+21
| | | | | | | | | The naming used in the driver for some functions is not very clear what the functions are really doing. To make this a bit easier to understand we rename few functions which were badly named.
