Subject: [PATCH 2/9] eeprom: at24: new flag in platform_data
Date: Mon, 12 Oct 2015 16:31:14 +0200	[thread overview]
Message-ID: <1444660281-19150-3-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1444660281-19150-1-git-send-email-bgolaszewski@baylibre.com>

In preparation for supporting the at24cs EEPROM series add a new flag to
platform data. When set, it should tell the driver that the chip has an
additional read-only memory area that holds a factory pre-programmed serial
number.
