There were three fields used in the DT version of probing this driver which were not yet in ACPI so handle those fields as well.
samsung,i2c-sda-delay = <100>; samsung,i2c-max-bus-freq = <20000>; samsung,i2c-slave-addr = <0x66>;
becomes
Method (DLAY, 0x0, NotSerialized) { Return (100) }
Method (SADD, 0x0, NotSerialized) { Return (0x66) }
Method (FREQ, 0x0, NotSerialized) { Return (20000) }
Thanks
