The last sentence wording is confusing because it sounds like a DeepSleep control bit still needs to be enabled which is not seen in the patch. If possible, drop this sentence and do the same for the other similar patch in this series. > Remove the unnecessary DeepSleep state configuration from USB1_DRVBUS pin, > as the DeepSleep control bit is not set and the active configuration is > sufficient to keep the pin pulled up.
