If we are in a multi-master scenario, we need to block runtime PM so the arbitration circuit stays awake. So, we define a new binding and adapt the i2c-rcar driver to have an example implementation. Changes since RFC: * added acks from Rob and Geert (thanks!) * use of_property_read_bool() now instead of of_get_property (thanks Sergei) * way more testing Wolfram Sang (3): i2c: document binding for multi-master case i2c: rcar: remove macros dealing with flags i2c: rcar: disable PM in multi-master mode Documentation/devicetree/bindings/i2c/i2c.txt | 5 ++++ drivers/i2c/busses/i2c-rcar.c | 39 ++++++++++++++++----------- 2 files changed, 28 insertions(+), 16 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
