+ * incrementing 8-bit counter per input report, but it is not very
+ * useful for this purpose (it is not entirely clear what rate it
+ * increments at or if it varies based on packet push rate - more on
+ * the push rate below...).
+ *
+ * The reverse engineering work done on the joy-cons and pro controllers
+ * by the community seems to indicate the following:
+ * - The controller samples the IMU every 1.35ms. It then does some of
+ * its own processing, probably averaging the samples out.
+ * - Each imu input report contains 3 IMU samples, (usually 5ms apart).
+ * - In the standard reporting mode (which this driver uses exclusively)
+ * input reports are pushed from the controller as follows:
+ * * joy-con (bluetooth): every 15 ms
+ * * joy-cons (in charging grip via USB): every 15 ms
+ * * pro controller (USB): every 15 ms
+ * * pro controller (bluetooth): every 8 ms (this is the wildcard)
+ *
+ * Further complicating matters is that some bluetooth stacks are known
+ * to alter the controller's packet rate by hardcoding the bluetooth
+ * SSR for the switch controllers (android's stack currently sets the
+ * SSR to 11ms for both the joy-cons and pro controllers).
+ *
+ * In my own testing, I've discovered that my pro controller either
+ * reports IMU sample batches every 11ms or every 15ms. This rate is
+ * stable after connecting. It isn't 100% clear what determines this
+ * rate. Importantly, even when sending every 11ms, none of the samples
+ * are duplicates. This seems to indicate that the time deltas between
+ * reported samples can vary based on the input report rate.
+ *
+ * The solution employed in this driver is to keep track of the average
+ * time delta between IMU input reports. In testing, this value has
+ * proven to be stable, staying at 15ms or 11ms, though other hardware
+ * configurations and bluetooth stacks could potentially see other rates
+ * (hopefully this will become more clear as more people use the
+ * driver).
+ *
+ * Keeping track of the average report delta allows us to submit our
+ * timestamps to userspace based on that. Each report contains 3
+ * samples, so the IMU sampling rate should be avg_time_delta/3. We can
+ * also use this average to detect events where we have dropped a
+ * packet. The userspace timestamp for the samples will be adjusted
+ * accordingly to prevent unwanted behvaior.
