This series adds support for capture to stm32-pwm driver. Capture is based on DMAs. - First two patches are precursor patches - Subsequent two patches add support for requesting DMAs to MFD core - Next three patches add support for capture to stm32-pwm driver - This has been tested on stm32429i-eval board.
