[PATCH v2 0/3] i3c dw,ast2600: Add a driver for the AST2600 i3c controller

[Jack Chen]

Hi Jeremy,
Thanks for the change, especially IBI features in other threads.
>From my understanding, ASPEED AST2600 is a SoC which uses Synopsys'
I3C IP core, and several different registers, especially the pull-up
resistor.
If so, I am wondering if this is the right place to add
ast2600-i3c-master.c, given that all current three xxx-i3c-master.c
drivers in this directory are from IP providers directly.
What about moving it under ~/driver/soc/?
Thanks
Zenghu Chen
