[PATCH v3 1/2] dt-bindings: watchdog: Add Exynos8855 watchdog compatible string

[PATCH v3 1/2] dt-bindings: watchdog: Add Exynos8855 watchdog compatible string

[Alim Akhtar]

Add the 'samsung,exynos8855-wdt' compatible string to the Samsung
watchdog device tree binding documentation. The Exynos8855 watchdog
nodes use two clocks (bus clock and source clock), require
samsung,cluster-index and samsung,syscon-phandle properties, similar
to Exynos850 watchdog implementation.
