Subject: [PATCH 0/8] Add STM32 LPTimer: PWM, trigger and counter
Date: Fri, 16 Jun 2017 17:58:38 +0200 [thread overview]
Message-ID: <1497628726-7563-1-git-send-email-fabrice.gasnier@st.com> (raw)
This series adds support for Low Power Timer that can be found on
some STM32 devices.
STM32 LPTimer (LPTIM) is a 16-bit timer that provides several
functionalities. This series adds support for following features:
- PWM output (with programmable prescaler, configurable polarity)
- Trigger source for STM32 ADC or DAC (LPTIM_OUT)
- Quadrature encoder and counter
The MFD core is used to manage common resources (clock, register,
reset) and to detect encoder feature. "stm32_lptimer" structure is
provided to its sub-nodes to share those information:
- PWM driver is used to implement single PWM channel
- IIO trigger
- IIO quadrature encoder and counter
