+Subject: [PATCH] touchscreen-meddling.patch
+
+Touchscreen on GTA01-02 experiences noise on the channel that serves the
+"tall axis" of the LCM.  The sample quality of the other axis is good.
+The bad samples have a characteristic of one shot excursions that can
+reach +/- 20% or more of the sample average.
+
+Previously, we had a simple averaging scheme going in the touchscreen
+driver that summed up 32 x and ys and then divided it by 32.  This patch
+first tidies up the existing code for style, then adds a new "running
+average" concept with a FIFO.  The running average is separate from the
+summing average mentioned above, and is accurate for the last n samples
+sample-by-sample, where n is set by 1 << excursion_filter_len_bits in the
+machine / platform stuff.
+
+The heuristic the patch implements for the filtering is to accept all
+samples, but tag the *previous* sample with a flag if it differed from
+the running average by more than reject_threshold_vs_avg in either
+axis.  The next sample time, a beauty contest is held if the flag was
+set to decide if we think the previous sample was a one-shot excursion
+(detected by the new sample being closer to the average than to the
+flagged previous sample), or if we believe we are moving (detected by
+the new sample being closer to the flagged previous sample than the
+average.  In the case that we believe the previous sample was an
+excursion, we simply overwrite it with the new data and adjust the
+summing average to use the new data instead of the excursion data.
+
+I only tested this by eyeballing the output of ts_print_raw, but it
+seemed to be quite a bit better.  Gross movement appeared to be
+tracked fine too.  If folks want to try different heuristics on top
+of this patch, be my guest; either way feedback on what it looks like
+with a graphical app would be good.
