The SAMV7's qencoder driver now supports the GETINDEX ioctl call which does not reset the internal Timer/Counter and returns the current position, position of the last index and the number of captured indexes to a struct qe_index_s pointer. Because the SAMV7's timers are 16bit, the extension to 32 bits must be done. Select CONFIG_SAMV7_QENCODER_ENABLE_GETINDEX in the Kconfig to enable this functionality. This driver does not obey the instructions given in the ATSAMV7 2023 datasheet because the recommended trigger resets the internal counter which is not desired. Instead, a capture into capture A and capture B registers is used. This way if an event happens (the rising edge of the index signal), the current counter's value is captured.
