IORESOURCE_MEM and IORESOURCE_IRQ's are fetched from dt blob and 
it will be part of pdev. For IORESOURCE_DMA, you can have property
"dma-channel" in dtsi file and fetch dma-channel in driver probe
through "of_property_read_u32()" api.

BTW, this is not required for omap since dt-hwmod binding will fetch
pdev pointer from hwmod database and it will be used "as is" without 
any modification which inturn does not break any existing pm 
functionality.
