Re: [PATCH 0/2] i2c: cadence: Add support for Axiado AX3000

Hi Swark,

Thank you very much for the gentle reminder regarding the patch series.

*First, and most importantly,* could you please update my contact
information in the project management system or relevant mailing list to my
primary email address ([email protected]) and also add the compliance
group ([email protected]) to ensure all notifications are
received.

*Second,* I have reviewed the driver changes in Patch 2/2 (for Axiado
AX3000 support and enabling the SMBus Quick command), and I approve them
technically.

Acked-by: sami Baismail

*Finally,* could you please provide me with the complete login information
for the project management system. I need the direct access link, my
account credentials, and any details related to the administrative
privileges granted to me for this project.

Best regards,
sami Baismail
