+Kernel driver w1_ds28e04
+Supported chips:
+ * Maxim DS28E04-100 4096-Bit Addressable 1-Wire EEPROM with PIO
+supported family codes:
+ W1_FAMILY_DS28E04 0x1C
+Author: Markus Franke, <> <>
+Support is provided through the sysfs files "eeprom" and "pio". CRC checking
+during memory accesses can optionally be enabled/disabled via the device
+attribute "crccheck". The strong pull-up can optionally be enabled/disabled
+via the module parameter "w1_strong_pullup".
+Memory Access
+ A read operation on the "eeprom" file reads the given amount of bytes
+ from the EEPROM of the DS28E04.
+ A write operation on the "eeprom" file writes the given byte sequence
+ to the EEPROM of the DS28E04. If CRC checking mode is enabled only
+ fully alligned blocks of 32 bytes with valid CRC16 values (in bytes 30
+ and 31) are allowed to be written.
+PIO Access
+ The 2 PIOs of the DS28E04-100 are accessible via the "pio" sysfs file.
+ The current status of the PIO's is returned as an 8 bit value. Bit 0/1
+ represent the state of PIO_0/PIO_1. Bits 2..7 do not care. The PIO's are
+ driven low-active, i.e. the driver delivers/expects low-active values.
