From mboxrd@z Thu Jan 1 00:00:00 1970 From: peter.griffin@linaro.org (Peter Griffin) Date: Tue, 12 Apr 2016 14:57:28 +0100 Subject: [PATCH v2 4/4] ARM: STi: DT: STiH407: Add DT node for at24c256 eeprom In-Reply-To: <1460469448-9065-1-git-send-email-peter.griffin@linaro.org> References: <1460469448-9065-1-git-send-email-peter.griffin@linaro.org> Message-ID: <1460469448-9065-5-git-send-email-peter.griffin@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org More accurately describe the i2c bus hardware by including a dt node for the eeprom device. Now that at24c256 can be accessed via the nvmem framework it allows for example the stmmac driver to be extended to get the MAC address from the at24c256 eeprom.
