Signed-off-by: Javier Martinez Canillas Acked-by: Rob Herring Acked-by: Aaro Koskinen Acked-by: Tony Lindgren Acked-by: Lee Jones --- Changes in v6: - Mention CBUS address instead of I2C since that's the bus used (Wolfram Sang). - Add a "i2c-cbus-gpio" comptible and use cbus0 for parent node (Wolfram Sang). Changes in v5: - Add missing properties for interrupts to DT binding doc (Rob Herring). - Add Rob Herring's Acked-by tag. - Add Aaro Koskinen's Acked-by tag. - Add Acked-by: Tony Lindgren 's Acked-by tag. - Add Lee Jones 's Acked-by tag. Changes in v4: - Use "dt-bindings: mfd:" prefix in subject line (Rob Herring). - Add information about what functions the device serve (Lee Jones). - Avoid using MFD in Device Tree (Lee Jones).
