Add the SM4450 interconnect and pinctrl drivers as built-in for
support the Qualcomm SM4450 platform to boot to uart shell.

Why it cannot be =m?

Best regards,

Hi Krzysztof,
Because system haven't capacity of loading ko files at this time on
SM4450 platform, so setting to "Y".

Hm? System has this capability. All systems have. What is so different
on SM4450 comparing to everything else we have here?

No, this should be =m and you need to fix your system.

Best regards,
Krzysztof

Hi Krzysztof,
Find new way which can load ko files on SM4450 platform, still need use 
"Y", because of some other modules have dependence to these two config, 
like scm, smmu module drivers, uart shell console cannot be got if set 
to "m".

That's what I am asking, which device exactly needs it.

Also do test for setting these two config to "m" on SM8450 platform, get 
uart shell consle failed if so setting.

Yeah, this we know, I did this. I am asking about SM4450.

Why we have =m requirement when other drivers above are =Y?. Can we confirm
w/ Georgi? I am not aware that Interconnect drivers needs to be =m only.
