Re: [PATCH] w1: Add 1-wire slave device driver for DS28E04-100

[Markus Franke]

Dear Greg,

the file "pio" is used for reading the current PIO state of the
DS28E04-100. The "eeprom" file is for reading/writing the EEPROM memory
of the same device.

As already mentioned before this is exactly the way how other w1 slave
drivers are handling stuff like this. I could also wrap everything
within a character device driver if this the way you would prefer. If
not, then please give me some advise how to exchange these couple of
bytes between user and kernel space.

Best regards,
Markus Franke
