Subject: Re: [PATCH v3 0/2] firmware: arm_scmi/imx: Support dump syslog

Hi Sudeep,

Hope you're doing well. Apologies for following up again, but this v3 patchset
has been pending for quite some time. I wanted to check if everything looks
good on your end.

Could you please confirm whether you plan to pick both patches? Or do you need
an A-b from the i.MX maintainer for patch 2? Alternatively, I can ask Shawn to
pick patch 2 if you only intend to take patch 1.

Please let me know your thoughts.

Thanks,
Peng
