title: I2C Base Structure
id: i2c
version: 0.1
description: >
This binding gives the base structures for all I2C devices
dts: bindings: provide generic yaml description for i2c-devices Provide generic yaml description for i2c-devices such as sensors New yaml binding category 'parent/child' is added. It aims at binding two types of related node such as bus master and bus slave. In case of i2c-device object, parent property is 'bus' with value 'i2c'. In the mean time, i2c node gets child property bus. Master and slave bus values should match. As such, 'i2c' node is bus master and 'i2c-devices' nodes are bus slaves Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

yaml: fix properties syntax to 'mapping' instead of 'series' According to yaml syntaxic rules, 'properties' described in dts bindings yaml files could be seen as 'mapping'(key/value couple), instead of 'series' (list of single elements). yaml 'mappings' will then be converted by yaml python library as python 'dict' which will ease treatment (instead of current list as were before this commit). Same treatment is applied to 'inherits'. script extract_dts_inlcude is updated to take change of yaml_list structre into account. This allows some code simplification. Largest impact is yaml_collapse function which works now allow complete overload method on all the attributes of a yaml nodes. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

"#address-cells":
dts: i2c: Add missing #address-cell & #size-cell properties The I2C controller nodes are the root of the I2C bus for that controller and thus may have children nodes that represent the I2C devices on that controller. Thus we need to specify the #address-cell & #size-cell properties. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
