[PATCH v3 0/2] arm64: dts: intel: set alias for i3c controllers for agilex5 variants and derivatives

[Adrian Ng Ho Yin]

Agilex5 SoCFPGA variants and derivatives have 2 i3c controllers, a main
master and a secondary master. Setting the alias for both i3c controllers
to prevent bus id contention when both controllers are enabled which
results in driver probe failures.

I've applied both patches.

Nit: I'm getting this checkpatch warning:

WARNING: From:/Signed-off-by: email address mismatch: 'From: Adrian Ng 
Ho Yin <adrianhoyin.ng@altera.com>' != 'Signed-off-by: Adrian Ng Ho Yin 
<adrian.ho.yin.ng@altera.com>'

Please try to fix this up for future submissions.

Thanks,
Dinh
