[PATCH 5/5] arm64: dts: ti: k3-j7200*: Add bootph-* properties

[Limaye, Aniket]

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.

Can you add the right indentation here?
