[PATCH v2 0/2] eeprom: at24: write-protect pin support

2017-12-20 Thread Bartosz Golaszewski
AT24 EEPROMs have a write-protect pin, which - when pulled high - inhibits writes to the upper quadrant of memory (although it has been observed that on some chips it disables writing to the entire memory range). On some boards, this pin is connected to a GPIO and pulled high by default, which for
