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/[email protected] :
- 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/[email protected] :
- change to depend on ARCH_MESON || COMPILE_TEST
- check buffer max size in read
