Subject: Purpose of PCI address in ranges property
Date: Sun, 19 Mar 2017 19:44:48 +0530	[thread overview]
Message-ID: <26e69b06-dde2-2ed5-0288-ee5d58676d7e@gmail.com> (raw)

Hi,

When ranges property is being parsed using 
of_pci_get_host_bridge_resources, the pci address is being used for
calculating the offset for pci_add_resource_offset.

What is this offset for ?

So the cpu address is being used for programming memory base and limit 
registers ?

Thanks & Regards,
Valmiki
