When compiling a decompiled device tree blob created with dumpdtb, dtc complains
|
||
|
|
with:
|
||
|
|
|
||
|
|
/soc@e0000000/i2c@3000: incorrect #address-cells for I2C bus
|
||
|
|
/soc@e0000000/i2c@3000: incorrect #size-cells for I2C bus
|
||
|
|
|
||
|
|
Fix this by adding the missing device tree properties.
