NOTE: This is a resent of the DT Bindings and DTSI patches based on the Amlogic DT 64bit
GIT pull request from Kevin Hilman at [1].
Changes since v2 at http://lkml.kernel.org/r/1465546915-24229-1-git-send-email-narmstrong@baylibre.com :
- Move rng peripheral node into periphs simple-bus node
Add support for the Amlogic Meson SoCs Hardware Random generator as a hw_random char driver.
The generator is a single 32bit wide register.
Also adds the Meson GXBB SoC DTSI node and corresponding DT bindings.
Changes since v1 at http://lkml.kernel.org/r/1464943621-18278-1-git-send-email-narmstrong@baylibre.com :
- change to depend on ARCH_MESON || COMPILE_TEST
- check buffer max size in read

+Amlogic Meson Random number generator
+=====================================
+
+Required properties:
+
+- compatible : should be "amlogic,meson-rng"
+- reg : Specifies base physical address and size of the registers.
+
+Example:
+
+rng {
+ compatible = "amlogic,meson-rng";
+ reg = <0x0 0xc8834000 0x0 0x4>;
