SubjectRE: [PATCH 0/8] interconnect: support i.MX8MP
Date
All,

> Subject: [PATCH 0/8] interconnect: support i.MX8MP

I am going to send out V2 this week to address the comments until now.
But before that I would like to see if any one has any comments on the
design here.

Georgi, do you have comments on Patch 2 " interconnect: add device
managed bulk API"

Lucas, since you had comments when I first use syscon to configure NoC,
are you ok with the design to use interconnect in this patchset?

Thanks,
Peng.
