Subject: Re: [PATCH 5/5] arm64: dts: ti: k3-j7200*: Add bootph-* properties
Hi Manorit,
Had some comments below:
(Re-sending coz I forgot to change to plain-text formatting and the
mailing-list rejected it)

Should this be bootph-pre-ram?

Do we need to add bootph-all property to the parent "dmsc" node too?
For some reason, for me, boot is failing without the bootph-all property
in the parent "dmsc" node here, even though it;s added to the child
nodes below
Failing logs with current patch (boot gets stuck) : [0]
If I ONLY add the bootph-all property to the dmsc node as well, the
device boots up just fine.
