Chu Shu Chen 194d4e9ffd fix(touch_pad): modify touch pad read function and touch_pad_deinit ... The touch pad read function taks too much time within spin lock waiting for the "done bit". (about 7.6ms as we tested) So we try to use a mutex on the touch read function and any other functions might change the "done bit".		2017-03-11 11:42:44 +08:00
