In order to support multiple IC types for i2c/smbus protocol, add get ic type command and use this data when checking firmware page count and signature address. Signed-off-by: Duson Lin <dusonlin@emc.com.tw> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-04-20Input: elan_i2c - fix calculating number of x and y traces.Duson Lin1-2/+2
According to Elan's firmware engineers we should not be subtracting 1 form the raw number of x and y traces so that the pitch size is correct. For example, if the touchpad x resolution is 2800 and x trace number is 20, the pitch size of x should be 2800/20 = 140, not 2800/19 = 147.36.

2015-02-06Input: elan_i2c - fix wrong %p extensionRasmus Villemoes1-1/+1
There's no %px extension. From the context I think the intention was to dump the five bytes which were not as expected, and for that one should use %ph. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
