From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sakari Ailus Subject: [PATCH 3/8] dt: bindings: Add a binding for referencing EEPROM from camera sensors Date: Wed, 14 Jun 2017 12:47:14 +0300 Message-ID: <1497433639-13101-4-git-send-email-sakari.ailus@linux.intel.com> References: <1497433639-13101-1-git-send-email-sakari.ailus@linux.intel.com> Return-path: In-Reply-To: <1497433639-13101-1-git-send-email-sakari.ailus@linux.intel.com> Sender: linux-media-owner@vger.kernel.org To: linux-media@vger.kernel.org, linux-leds@vger.kernel.org Cc: devicetree@vger.kernel.org, sebastian.reichel@collabora.co.uk, robh@kernel.org, pavel@ucw.cz List-Id: devicetree@vger.kernel.org Many camera sensor devices contain EEPROM chips that describe the properties of a given unit --- the data is specific to a given unit can thus is not stored e.g. in user space or the driver. Some sensors embed the EEPROM chip and it can be accessed through the sensor's I2C interface. This property is to be used for devices where the EEPROM chip is accessed through a different I2C address than the sensor. The intent is to later provide this information to the user space.
