Subject: [RESEND PATCH 0/9] eeprom: at24: at24cs series serial number read
Date: Tue, 20 Oct 2015 10:43:18 +0200	[thread overview]
Message-ID: <1445330607-12470-1-git-send-email-bgolaszewski@baylibre.com> (raw)

Chips from the at24cs EEPROM series have an additional read-only memory area
containing a factory pre-programmed serial number. In order to access it, a
dummy write must be executed before reading the serial number bytes.

This series adds support for reading the serial number through a sysfs
attribute.

While we're at it: some of the patches contain readability tweaks and code
organization fixes.

Tested with at24cs64 and at24cs02 chips (for both 16 and 8 bit address
pointers).

Bartosz Golaszewski (9):
  eeprom: at24: platform_data: use BIT() macro
  eeprom: at24: new flag in platform_data
  eeprom: at24: tie up an additional address for at24cs series
  eeprom: at24: support reading of the serial number
  eeprom: at24: export the serial number through sysfs
  eeprom: at24: improve the device_id table readability
  eeprom: at24: add the at24cs series to the list of supported devices
  eeprom: at24: remove a reduntant if
  eeprom: at24: readability tweaks
