18 -----------
20 The DS2413 chip has two open-drain outputs (PIO A and PIO B).
21 Support is provided through the sysfs files "output" and "state".
23 Reading state
24 -------------
25 The "state" file provides one-byte value which is in the same format as for
29 Bit 0:   PIOA Pin State
30 Bit 1:   PIOA Output Latch State
31 Bit 2:   PIOB Pin State
32 Bit 3:   PIOB Output Latch State
33 Bit 4-7: Complement of Bit 3 to Bit 0 (verified by the kernel module)
39 --------------
41 It is writable, you can write one-byte value to this sysfs file.
47 Bit 2-7: No matter (driver will set it to "1"s)
52 When reading the state, there is a four complement bits.
58 If the write is unsuccessful for three times, the write also returns
