Input: wdt87xx_i2c - change the sleep time to 2500ms after the sw reset 2015-07-12T06:26:33+00:00 HungNien Chen hn.chen@weidahitech.com 2015-07-12T00:30:19+00:00 339d6b88e872f8369495a7224916a4d1d8376ca3 The original wait time was 200ms which was enough for the firmware to finish loading and boot. After that the firmware will perform initialization and touch calibration, which will take about 1.1 second. The touch calibration will change controller frequency to scan at the most optimal frequency and during calibration/frequency switching process we may run into i2c data errors. To avoid them we extend the sleep to 2500ms after issuing the sw reset. Signed-off-by: HungNien Chen <hn.chen@weidahitech.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
