-Subject: Input: wacom - add a quirk for low resolution Bamboo devices
-X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fdtor%2Finput.git;a=commitdiff_plain;h=f4ccbef2886968ed409939531f6dd0474d53a12a

-Input: wacom - add a quirk for low resolution Bamboo devices
-
-The Bamboo Touch reports a sub-screen resolution of 480x320. The
-signal-to-noise ratio is only about 100, so filtering is needed in
-order to reduce the jitter to a usable level. However, the low
-resolution leads to round-off errors in the EWMA filter, resulting in
-extremely jerky pointer motion. This patch explicitly sets a higher
-resolution for those devices, and tells this to the completion handler
-via a low-resolution quirk.
