| * pcf50633: Query charger status directlyPaul Fertser2009-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Current scheme is fragile and is likely to go off sync, especially on batfull->adapter charging automatic MBC transition. Query the status bit every time we need it instead. We need to export another function to query for USB presence because we can't read anything from PCF50633 (via I2C) inside irq context and that is needed by usb gadgets.

| * pcf50633: Get rid of charging restart software auto-triggeringPaul Fertser2009-11-161-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
| * pcf50633: introduces battery charging current controlBalaji Rao2009-11-161-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new sysfs attribute to allow changing MBC charging limit on the fly independently of usb current limit. It also gets set automatically every time usb current limit is changed. Limiting charging current also prevents violating USB specification in the case when the whole device is shut down and usb current limit is reset to the factory default by the pcf50633 state transition.

* | mfd: Remove ezx-pcap defines for custom led gpio encodingAntonio Ospite2009-12-131-3/+0
| | | | | | | | | | | | | | | | | | | | | | We used these, in a first version of leds-pcap driver, in order to encode gpio enabling and gpio inversion for a led inside the variable used for the gpio number. In the new leds-pcap driver we rely on gpio_is_valid() to derive if a led is gpio enabled and we have a dedicated flag to tell if the gpio value has to be inverted.

* | mfd: Near complete mc13783 rewriteUwe Kleine-König2009-12-132-217/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes several things while still providing the old API: - simplify and fix locking - better error handling - don't ack all irqs making it impossible to detect a reset of the rtc - use a timeout variant to wait for completion of ADC conversion - provide platform-data to regulator subdevice (This allows making struct mc13783 opaque for other drivers after the regulator driver is updated to use its platform_data.) - expose all interrupts - use threaded irq After all users in mainline are converted to the new API, some things (e.g. mc13783-private.h) can go away.

* | mfd: Move WM831x to generic IRQMark Brown2009-12-132-11/+30
| | | | | | | | | | | | | | | | | | | | | | Replace the wm831x-local IRQ infrastructure with genirq, allowing access to the diagnostic infrastructure of genirq and allowing us to implement interrupt support for the GPIOs. The switchover is done within the wm831x specific IRQ API, further patches will convert the individual drivers to use genirq directly.

* | mfd: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen2009-12-131-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

* | mfd: Convert WM835x IRQ handling to use a data tableMark Brown2009-12-131-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

| |/ | | | | | | | | | | | | | | | | | | | | | | The WM831x series of devices provide a watchdog with configurable behaviour on timer expiry. Currently this driver support refreshes via a register or GPIO line and autonomous refreshes from a hardware source (eg, a clock).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.

* | mfd: AB3100 accessor function cleanupsLinus Walleij2009-09-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds the _interruptible suffix to the AB3100 accessor functions on par with mutex_lock_interruptible() that's used for blocking simultaneous calls to the AB3100 acessor functions. Since these accesses are slow on a 100kHz I2C bus and may line up waiting for the mutex, we need to handle interruption by system shutdown or kill signals and may just as well denote that in the function names.

* | regulator: Add WM831x LDO supportMark Brown2009-09-171-0/+626
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WM831x series of devices provide three types of LDO: - General purpose LDOs supporting voltages from 0.9-3.3V - High performance analogue LDOs supporting voltages from 1-3.5V - Very low power consumption LDOs intended to support always on functionality. This patch adds support for all three kinds of LDO. Each regulator is probed as an individual platform device with resources used to provide the register map location of the regulator. Mixed hardware and software control of regulators is not current supported.

| | | | | | | | | | | | | | | | | | | | | | | | The WM831x series of devices all have 3 DC-DC buck convertors. This driver implements software control for these regulators via the regulator API. Use with split hardware/software control of individual regulators is not supported, though regulators not controlled by software may be controlled via the hardware control interfaces.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the GPIO pins on the WM831x. No direct support is currently supplied for configuring non-gpiolib functionality such as pull configuration and alternate functions, soft configuration of these will be provided in a future patch. Currently use of these pins as interrupts is not supported due to the ongoing issues with generic irq not support interrupt controllers on interrupt driven buses. Users can directly request the interrupts with the wm831x-specific APIs currently provided if required.

* | mfd: Export ISEL values from WM831x coreMark Brown2009-09-171-0/+21
| | | | | | | | | | | | | | | | | | | | | | The current settings which can be used with the WM831x current sinks can't easily be mapped between register values and currents at run time without a lookup table since the values scale logarithmically to match the way the human eye interprets brightness. This lookup table is inclided in the core since several drivers need to use it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
