+Subject: [PATCH] of: address: Follow DMA parent for "dma-coherent"
+
+commit c60bf3eb888a362100aa1bdbea351dab681e262a upstream.
+
+Much like for address translation, when checking for DMA coherence we
+should be sure to walk up the DMA hierarchy, rather than the MMIO one,
+now that we can accommodate them being different.
