Sorry, I got this in the wrong place, the hwlock node should sit outside
of soc {} - looks like we got this wrong in msm8916 as well.
Thanks for reviewing the patch. Do you mean to move it under / {}; (i.e.
root)?
Yes. Any node that doesn't have reg properties should go under the root.
Got it. Will update the patch(es) and add cover letter. Thanks.
Andy
