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, make development of new platforms easier and allow to make cleanup of the existing code and device tree files, lets mark some 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.

Add specific compatibles to mark unstable. v1 is here: https://patchwork.kernel.org/patch/9477963/ Previous tags (not applying due to change in contents): Reviewed-by: Javier Martinez Canillas Acked-by: Bartlomiej Zolnierkiewicz Reviewed-by: Pankaj Dubey --- .../devicetree/bindings/arm/samsung/exynos.txt | 26 ++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/samsung/exynos.txt -- 2.14.1 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Reviewed-by: Javier Martinez Canillas diff --git a/Documentation/devicetree/bindings/arm/samsung/exynos.txt b/Documentation/devicetree/bindings/arm/samsung/exynos.txt new file mode 100644 index 000000000000..7410cb79e4b2 --- /dev/null +++ b/Documentation/devicetree/bindings/arm/samsung/exynos.txt @@ -0,0 +1,26 @@ +Samsung Exynos SoC Family Device Tree Bindings +--------------------------------------------------------------- + +Work in progress statement: + +Following Device Tree files and bindings applying to Samsung Exynos SoCs and +boards are considered "unstable": + + - samsung,exynos5433* (all compatibles related to Exynos5433) + - samsung,exynos7* (all compatibles related to Exynos7) + - samsung,tm2-audio + - samsung,mfc-v10 + - samsung,exynos*-mipi-dsi + - samsung,exynos5-dp + - samsung,exynos*-hdmi + - samsung,exynos*-hdmiddc + - samsung,exynos*-hdmiphy + - samsung,exynos*-mixer + - samsung,exynos*-fimd + +Any Samsung Exynos device tree binding mentioned may change at any time.
