Subject: Correct way to set coherent_dma_mask on a non-pci device?
Date: Tue, 08 Jul 2008 13:40:06 -0400	[thread overview]
Message-ID: <4873A676.8050906@cortland.com> (raw)

There appears to be no function like pci_set_consistent_dma_mask to set 
the coherent mask for a non-pci device.

What is the "proper" way to set it?

The context for the question is a recent change to ssb_dma_set_mask() in 
drivers/ssb/main.c that removed the somewhat fragile, direct 
manipulation of dma_mask and coherent_dma_mask in favor of a call to 
dma_set_mask().

Thanks,
Steve
