Subject: [RFC PATCH v3 0/2] Expose DMA_MEMORY_EXCLUSIVE through shared-dma-pool
Date: Tue, 10 Nov 2015 17:18:25 +0100 [thread overview]
Message-ID: <564218D1.2030008@baylibre.com> (raw)
The shared-dma-pool dt node only exposes exclusive memory, but in order to export
non-exclusive coherent memory, add the no-exclusive property and document it.
v3: use correct of_get_flat_dt_prop helper
v2: simplify patch by looking for DT attribute in callback
Neil Armstrong (2):
base: dma-coherent: Add DT property for non exclusive shared-dma-pool
devicetree: reserved-memory: document the optional no-exclusive parameter
