* mfd: Initial core support for WM831x series devicesMark Brown2009-09-172-0/+354
| | | | | | | | | | | | | | The WM831x series of devices are register compatible processor power management subsystems, providing regulator and power path management facilities along with other services like watchdog, RTC and touch panel controllers. This patch adds very basic support, providing basic single register I2C access, handling of the security key and registration of the devices.

* mfd: Allow multiple MFD cells with the same nameMark Brown2009-09-171-0/+1
| | | | | | | | | | | | | | | Provide basic support for MFDs having multiple cells of a given type with different IDs by adding an id to the mfd_cell structure and then adding that to the id passed in to mfd_add_devices(). As it stands this approach requires that MFDs using this feature deal with ensuring that there aren't any ID collisions resulting from multiple MFDs of the same type being instantiated. This needs to happen with the existing code too, but with this approach there is a knock on effect on the IDs for non-duplicated devices.

* mfd: use a dedicated workqueue for pcf50633 irq processingPaul Fertser2009-09-171-0/+1
| | | | | | | | | | | | | | Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

* mfd: add PCAP driverDaniel Ribeiro2009-06-171-0/+256
| | | | | | | | | | | | | | | | | | The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The battery charger state machine switches into charging mode when the battery voltage falls below 96% of a battery float voltage. But 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 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.

* | mfd: remove DS1WM clock handlingPhilipp Zabel2009-04-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This driver requests a clock that usually is supplied by the MFD in which the DS1WM is contained. Currently, it is impossible for a MFD to register their clocks with the generic clock API due to different implementations across architectures. For now, this patch removes the clock handling from DS1WM altogether, trusting that the MFD enable/disable functions will switch the clock if needed. The clock rate is obtained from a new parameter in driver_data. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>

| * leds: Add WM8350 LED driverMark Brown2009-01-081-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The voltage and current regulators on the WM8350 AudioPlus PMIC can be used in concert to provide a power efficient LED driver. This driver implements support for this within the standard LED class. Platform initialisation code should configure the LED hardware in the init callback provided by the WM8350 core driver. The callback should use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and wm8350_dcdc_set_slot() to configure the operating parameters of the regulators for their hardware and then then use wm8350_register_led() to instantiate the LED driver.
