-Samsung Exynos SoC Low Power Audio Subsystem (LPASS)
-
-Required properties:
-
- - compatible		: "samsung,exynos5433-lpass"
- - reg			: should contain the LPASS top SFR region location
-			  and size
- - clock-names		: should contain following required clocks: "sfr0_ctrl"
- - clocks		: should contain clock specifiers of all clocks, which
-			  input names have been specified in clock-names
-			  property, in same order.
- - #address-cells	: should be 1
- - #size-cells		: should be 1
- - ranges		: must be present
-
-Each IP block of the Low Power Audio Subsystem should be specified as
-an optional sub-node. For "samsung,exynos5433-lpass" compatible this includes:
-UART, SLIMBUS, PCM, I2S, DMAC, Timers 0...4, VIC, WDT 0...1 devices.
-
-Bindings of the sub-nodes are described in:
-  ../serial/samsung_uart.yaml
-  ../sound/samsung-i2s.txt
-  ../dma/arm-pl330.txt
-
-
-Example:
-
