[PATCHv5 3/5] Input: edt-ft5x06: Adjust delays to conform datasheet

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The FT5x06 datasheet specifies a minimum reset width of 5ms and a
delay between deassertion of reset and start of reporting of 300ms.
Adjust the delays to conform to the datasheet.

With the original delays I sometimes experienced communication
timeouts when initializing the controller.
