-Ion Memory Manager
-
-Ion is a memory manager that allows for sharing of buffers via dma-buf.
-Ion allows for different types of allocation via an abstraction called
-a 'heap'. A heap represents a specific type of memory. Each heap has
-a different type. There can be multiple instances of the same heap
-type.
-
-Specific heap instances are tied to heap IDs. Heap IDs are not to be specified
-in the devicetree.
-
-Required properties for Ion
-
-- compatible: "linux,ion" PLUS a compatible property for the device
-
-All child nodes of a linux,ion node are interpreted as heaps
-
-required properties for heaps
-
-- compatible: compatible string for a heap type PLUS a compatible property
-for the specific instance of the heap. Current heap types
--- linux,ion-heap-system
--- linux,ion-heap-system-contig
--- linux,ion-heap-carveout
--- linux,ion-heap-chunk
--- linux,ion-heap-dma
--- linux,ion-heap-custom
-
-Optional properties
-- memory-region: A phandle to a memory region. Required for DMA heap type
-(see reserved-memory.txt for details on the reservation)
-
-Example:
-
- ion {
- compatbile = "hisilicon,ion", "linux,ion";
-
- ion-system-heap {
- compatbile = "hisilicon,system-heap", "linux,ion-heap-system"
- };
-
- ion-camera-region {
- compatible = "hisilicon,camera-heap", "linux,ion-heap-dma"
- memory-region = <&camera_region>;
- };
-
- ion-fb-region {
- compatbile = "hisilicon,fb-heap", "linux,ion-heap-dma"
- memory-region = <&fb_region>;
- };
- }
