But if there aren't any other child nodes for the SRC, then why do you 
need this level at all? If there are others, then your binding is 
incomplete.

Currently we not need other parts from driver, so I not add them. I just add mix
slices with name "slices". For U-Boot, we are not using DTB for mem slices,
so I not add mem slices.
It has following mix slices.
0 EdgeLock Enclave
1 AONMIX
2 WAKEUPMIX
3 DDRMIX
4 DDRPHY
5 MLMIX
6 NICMIX
7 HSIOMIX
8 MEDIAMIX
9 CM33MIX
10 CA55 core 0
11 CA55 core 1
12 CA55 cluster
It has following mem slices:
0 AONMIX memory
1 WAKEUPMIX memory
2 DDRMIX memory
3 DDRPHY memory
4 MLMIX memory
5 NICMIX memory
6 OCRAM
7 HSIOMIX memory
8 MEDIA memory
9 CA55 core 0 memory
10 CA55 core 1 memory
11 CA55 cluster memory
12 L3 cache
It has some general purpose functions that could
be covered by SRC node itself.
Thanks,
Peng.

Please make bindings as complete as possible, not what some u-boot or

i.MX9 has many logic block named [x]mix, such as wakeupmix,
mediamix. One mix slice is for one mix block logic.

From HW perspective, registers are actually memory.
So saying mem slice is for memory related stuff for
a mix.

Stephen,
> Subject: [PATCH V4 3/7] clk: export of_clk_bulk_get_all
Are you fine with this patch?
Patch 4 "soc: imx: add i.MX93 SRC power domain driver"
depends on this patch, if you are not happy with patch 3,
I still have time to rework patch 4.
Thanks,
Peng.
