Hi all
May I know if I miss anything to let this patch be reviewed?
I will do my best to fix the problems.
Thanks a lot.

the root and initrd parameters seems really specific for your way you boot the
board, but are not necessary to boot e.g. with a initramfs.
Please delete this two parameters.
Apart instead of console please use stdout-path to specify to which uart the
console should be connected.
Thanks,
Matthias

Thanks for this suggestion. I will remove these two parameters in next
version.

Got it, the chosen node in the next version will be:
chosen {
bootargs = "console=ttyS0,921600n8 earlyprintk";
stdout-path = &uart0;
};

May I know the reason to remove the soc node? I follow other xxxx.dtsi
to add this node.
Thanks.

The device tree is reflecting the hardware, if you add a soc node like this, it
is seen like a bus, but there is not really a bus.
I think point of view about this has change over time and nowadays it is
preferred not to add a soc node.

Matthias

Got it. Will remove the soc node and prepare the new patch.
Thanks a lot.
Hi Matthias
May I double confirm with you that soc node is MUST removed?
If yes, we will upstream dtsi with this format for other new chips.
Thanks.
