5 and multiple alternate functions(ALT1 - ALTx) that directly connect
9 Pull Up (PU) are driven by the related PIO block.
11 ST pinctrl driver controls PIO multiplexing block and also interacts with

Dw1_ds2413.rst7 * Maxim DS2413 1-Wire Dual Channel Addressable Switch
18 -----------
20 The DS2413 chip has two open-drain outputs (PIO A and PIO B).
24 -------------
25 The "state" file provides one-byte value which is in the same format as for
33 Bit 4-7: Complement of Bit 3 to Bit 0 (verified by the kernel module)
39 --------------
40 You can set the PIO pins using the "output" file.
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)
