2012-09-25backlight: Add TPS65217 WLED driverMatthias Kaehlcke3-0/+360
The TPS65217 chip contains a boost converter and current sinks which can be used to drive LEDs for use as backlights. Expose this functionality via the backlight API. Tested on an AM335x based custom board with a single WLED string, using different values for ISEL and FDIM (though it would be hard to tell the difference except for the value in WLEDCTRL1). Both instantiation through the device tree and by passing platform data have been tested. Testing has been done with an Androidized 3.2 kernel from the rowboat project. Koen Kooi reported the driver to be working on a Beaglebone board with LCD3 cape Signed-off-by: Matthias Kaehlcke <matthias@kaehlcke.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-09-23mfd: Add lp8788 mfd driverMilo Kim4-0/+455
TI LP8788 PMU provides regulators, battery charger, ADC, RTC, backlight driver and current sinks. This MFD patch supports the I2C communication using the regmap, the interrupt handling using the linear IRQ domain and configurable platform data structures for each driver module. (Driver Architecture) < mfd devices > LP8788 HW .......... mfd .......... regulator drivers I2C power supply driver IRQs iio adc driver rtc driver backlight driver current sink drivers o regulators : LDOs and BUCKs o power supply : Battery charger o iio adc : Battery voltage/temperature o rtc : RTC and alarm o backlight o current sink : LED and vibrator All MFD device modules are registered by LP8788 MFD core driver. For sharing information such like the virtual IRQ number, MFD core driver uses the resource structure. Then each module can retrieve the specific IRQ number and detect it in the IRQ thread. Configurable platform data is handled in each driver module. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-09-23mfd: rc5t583: Fix warning messagesVenu Byravarasu2-2/+2
Two variables named master_int and sleepseq_val, were just declared without initialization. Pointers to these variables were passed to mfd read function. After that these variables were used for some of the logical operations. Though logically there is nothing wrong, compiler is complaining that the variables may be used uninitialized.
