[Xen-devel] Compatible string for psci node: v1.0?

[Mirela Simonovic <mirela.simonovic@xxxxxxxxxx>]

Hi,


I'm working on switching to PSCI v1.0 in Xen (needed to support suspend 
to RAM).
In addition to updates in PSCI implementation, we assumed that 
compatible property in psci device tree node should be extended with 
"arm,psci-1.0" (not a must since this doesn't affect Dom0's 
functionality today, but I would add it if possible).
Could you please let me know how to add "arm,psci-1.0" to compatible 
property?
I assumed that in domain_build.c in make_psci_node() function I need to 
add "arm,psci-1.0""\0" at the beginning of 'compat' string (although I 
don't understand the "\0"). That doesn't seem to work. Only 
"arm,psci-1.0" ends up in compatible property and we need strings for 
older versions as well.
I also noticed that even "arm,psci" doesn't appear to be added into the 
compatible property (without any code modifications from my side). I 
checked what is generated by debugging and by 'cat' on 
/sys/firmware/devicetree/base/psci/compatible from Dom0's console.
Thanks,
Mirela
