   1 * Device tree bindings for Aspeed Video Engine
   2
   3 The Video Engine (VE) embedded in the Aspeed AST2400/2500/2600 SOCs can
   4 capture and compress video data from digital or analog sources.

   6 Required properties:
   7  - compatible:          "aspeed,ast2400-video-engine" or
   8                         "aspeed,ast2500-video-engine" or
   9                         "aspeed,ast2600-video-engine"
  10  - reg:                 contains the offset and length of the VE memory region
  11  - clocks:              clock specifiers for the syscon clocks associated with
  12                         the VE (ordering must match the clock-names property)
  13  - clock-names:         "vclk" and "eclk"
  14  - resets:              reset specifier for the syscon reset associated with
  15                         the VE
  16  - interrupts:          the interrupt associated with the VE on this platform
  17
  18 Optional properties:
  19  - memory-region:
  20         phandle to a memory region to allocate from, as defined in
  21         Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
