Signed-off-by: Sylwester Nawrocki Acked-by: Rob Herring --- There were few rather significant additions since v3 and I had to drop tags: Acked-by: Rob Herring Acked-by: Krzysztof Kozlowski Changes since v3: - moved to Documentation/devicetree/bindings/mfd, - added #address-cells, #size-cells, ranges as required properties, - added description of the IP block subnodes and links to their binding's documentation. Changes since v2: - none. --- .../bindings/mfd/samsung,exynos5433-lpass.txt | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/samsung,exynos5433-lpass.txt diff --git a/Documentation/devicetree/bindings/mfd/samsung,exynos5433-lpass.txt b/Documentation/devicetree/bindings/mfd/samsung,exynos5433-lpass.txt new file mode 100644 index 0000000..7e97c0d --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/samsung,exynos5433-lpass.txt @@ -0,0 +1,21 @@ + +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 + - samsung,pmu-syscon : the phandle to the Power Management Unit node + - #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.
