| Message-ID | <ujp9w-4iA-5@gated-at.bofh.it> |
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 map) 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 --- Resend v3 with collected Acks Changes in v3: - I sent this v3 with various changes, but still need to discuss ABI for counter driver (no change on this in v3). - Remarks for Rob on dt-bindings - Add validate_device in Trigger driver - Update PWM driver after Thierry's comments - Additional patch for STM32 ADC trigger Changes in v2: - Various remarks from Lee, on MFD part, extended to the full series, such as: clock name, use "Low-Power Timer", file headers, dt-bindings props descriptions, fix dt example.
