Hi All, I have decided to split this series into multiple smaller ones as follows: - Patches 1/21 - 11/21, 13/21 - 14/21, 19/21: will split them to each subsystem specific patch sets. - Patches 15/21 - 18/21: will come in separate series along with QUPs driver changes. - Patches 20/21 - 21/21: will come in separate series after above two sets are accepted.
