Subject: Re: [PATCH v2 00/21] arm64: qcom: Introduce SA8255p Ride platform
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.
Thanks,
-Nikunj
