Subject: [PATCH v2 2/3] ARM: dts: samsung: exynos4: fix camera unit addresses/ranges
The camera node has both unit address and children within the same bus
mapping, thus needs proper ranges property to fix dtc W=1 warnings:
Warning (unit_address_vs_reg): /soc/camera@...00000: node has a unit name, but no reg or ranges property
Warning (simple_bus_reg): /soc/camera@...00000: missing or empty reg/ranges property
Subtract 0x11800000 from all its children nodes. No functional impact
expected.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

Changes in v2:
1. Move ranges after compatible
