When more than one value, means undefined length burst mode, USB controller can use the length less than or equal to the largest enabled burst length. While enabling undefined length INCR burst type and INCR16 burst type, get better write performance on NXP Layerscape platforms: around 3% improvement (from 364MB/s to 375MB/s). Signed-off-by: Ran Wang Signed-off-by: Pengbo Mu --- Changes in v6: - delete snps,incr-burst-type-adjustment = <1> Changes in v5: - add support for ls1021a, ls1012a, ls1046a, ls1088a, ls1021a - update ls208xa support according to code base change Changes in v4: - change definition for this property.
