It also introduces a new tool that can be used for testing. Then, it improves the stm32 timer counter driver by introducing new signals, e.g. counting frequency, and missing channels. It also adds support for interrupt based events using the chrdev interface. Two event types are added in this series: overflows and capture. Up to now, stm32 timer counter driver focused mainly on quadrature encoder feature. With this series, all timer instances can be enabled for simple counting (with overflow and capture events).
