Samsung Exynos SoCs and boards related bindings evolved since the initial introduction, but initially the bindings were minimal and a bit incomplete (they never described all the hardware modules available in the SoCs). Since then some significant (not fully compatible) changes have been already committed a few times (like gpio replaced by pinctrl, display ddc, mfc reserved memory, some core clocks added to various hardware modules, added more required nodes). On the other side there are no boards which have device tree embedded in the bootloader. Device tree blob is always compiled from the kernel tree and updated together with the kernel image. Thus to avoid further adding a bunch of workarounds for old/missing bindings and allow to make cleanup of the existing code and device tree files, lets mark Samsung Exynos SoC platform bindings as unstable. This means that bindings can may change at any time and users should use the dtb file compiled from the same kernel source tree as the kernel image.
