2011-07-31mfd: Don't leak init_data in tps65910_i2c_probeJesper Juhl
There are a couple of situations where we leak init_data in drivers/mfd/tps65910.c:tps65910_i2c_probe() - this patch should take care of them. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-07-31mfd: Implement tps65910 IRQ cleanupMark Brown
The tps65910_irq_exit() cleanup function was generating a warning from sparse due to the lack of a prototype. This wasn't causing GCC warnings as the driver wasn't cleaning up its IRQs on exit at all so there was no use of an unprototyped function.

2011-05-27MFD: TPS65910: Add support for TPS65911 deviceJorge Eduardo Candelaria
The TPS65911 is the next generation of the TPS65910 family of PMIC chips. It adds a few features: - Watchdog Timer - PWM & LED generators - Comparators for system control status It also adds a set of Interrupts and GPIOs, among other things. The driver exports a function to identify between different versions of the tps65910 family, allowing other modules to identify the capabilities of the current chip.

2011-05-27mfd: Fix off-by-one value range checking for tps65910_i2c_writeAxel Lin
If bytes == (TPS65910_MAX_REGISTER + 1), we have a buffer overflow when doing memcpy(&msg[1], src, bytes). Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2011-05-27TPS65910: IRQ: Add interrupt controllerGraeme Gregory
This module controls the interrupt handling for the tps chip. The interrupt sources are the following: - GPIO falling/rising edge detection - Battery voltage below/above threshold - PWRON signal - PWRHOLD signal - Temperature detection - RTC alarm and periodic event Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk> Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2011-05-27TPS65910: GPIO: Add GPIO driverGraeme Gregory
TPS65910 has one configurable GPIO that can be used for several purposes. Subsequent versions of the TPS chip support more than one GPIO.

2011-05-27MFD: TPS65910: Add new mfd device for TPS65910Graeme Gregory
The TPS65910 chip is a power management IC for multimedia and handheld devices. It contains the following components: - Regulators - GPIO controller - RTC The tps65910 core driver is registered as a platform driver and provides communication through I2C with the host device for the different components.
