This means that we are getting incorrect durations (REG1_TIME_IV) reported from the hardware. This problem was also noticed by some people trying to use this on an ODROID-C1 and ODROID-C2 - the workaround there (probably because the datasheets were not publicy available yet at that time) was to switch to ir_raw_event_store_edge (which leaves it up to the kernel to measure the duration of a pulse). See [0] and [1] for the corresponding patches. Please note that I was only able to test this on an GXBB/S905 based device (due to lack of other hardware).
