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). (rebased against 4.4-rc3) v2: - protect the serial number read with a mutex v1: https://lkml.org/lkml/2015/10/20/162 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 drivers/misc/eeprom/at24.c | 187 +++++++++++++++++++++++++++++++------ include/linux/platform_data/at24.h | 9 +- 2 files changed, 166 insertions(+), 30 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
