This patch adds documentation of the DT bindings for the Samsung
Exynos SoC Low Power Audio Subsystem.
Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>
---
There were few rather significant additions since v3 and I had to drop tags:
Acked-by: Rob Herring <robh@kernel.org>
Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
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.

These look so much better like:
- 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

Use relative path names:
../serial/samsung_uart.txt
../sound/samsung-i2s.txt
../dma/arm-pl330.txt
Missing example?

OK, actually I had it this way in one of the versions but somehow
with full paths it appeared better to me.

Yes, omitted deliberately as that appeared quite many more lines
with fully specified subnodes. Perhaps I will add it with omitted
all properties of the subnodes but compatible.
