Pull pwm changes from Thierry Reding: "A new driver has been added for the SPEAr platform and the TWL4030/6030 driver has been replaced by two drivers that control the regular PWMs and the PWM driven LEDs provided by the chips. The vt8500, tiecap, tiehrpwm, i.MX, LPC32xx and Samsung drivers have all been improved and the device tree bindings now support the PWM signal polarity." Fix up trivial conflicts due to __devinit/exit removal. * tag 'for-3.8-rc1' of git://gitorious.org/linux-pwm/linux-pwm: (21 commits) pwm: samsung: add missing s3c->pwm_id assignment pwm: lpc32xx: Set the chip base for dynamic allocation pwm: lpc32xx: Properly disable the clock on device removal pwm: lpc32xx: Fix the PWM polarity pwm: i.MX: eliminate build warning pwm: Export of_pwm_xlate_with_flags() pwm: Remove pwm-twl6030 driver pwm: New driver to support PWM driven LEDs on TWL4030/6030 series of PMICs pwm: New driver to support PWMs on TWL4030/6030 series of PMICs pwm: pwm-tiehrpwm: pinctrl support pwm: tiehrpwm: Add device-tree binding pwm: pwm-tiehrpwm: Adding TBCLK gating support. pwm: pwm-tiecap: pinctrl support pwm: tiecap: Add device-tree binding pwm: Add TI PWM subsystem driver pwm: Device tree support for PWM polarity pwm: vt8500: Ensure PWM clock is enabled during pwm_config pwm: vt8500: Fix build error pwm: spear: Staticize spear_pwm_config() pwm: Add SPEAr PWM chip driver support ...

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Acked-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-10-05pwm: Check for negative duty-cycle and periodThierry Reding
Make sure the duty-cycle and period passed in are not negative. This should eventually be made implicit by making them unsigned. While at it, the drivers' .config() implementations can have the equivalent checks removed.
