H A D | mxc_w1.c | f80b2581 Thu May 08 02:56:40 CDT 2014 Alexander Shiyan <shc_work@mail.ru> w1: mxc_w1: Optimize mxc_w1_ds2_touch_bit()
According to the i.MX reference manual, the read/write bit operations takes from 60 us to 120 us. This patch optimizes mxc_w1_ds2_touch_bit() function to use proper value for such delay. Nevertheless, a small margin for the timeout has been added for the case if clock frequency is inaccurate.
