[PATCH 0/2] hwrng: iproc-rng200: Add support for BCM7278

[Florian Fainelli]

Hi,

This patch series adds support for the RNG200 block found on the BCM7278 SoC.
This requires us to update the compatible string (and associated binding
document) as well as the Kconfig option to make that driver selectable with
ARCH_BRCMSTB gating the enabling of such SoCs.

Thank you

[PATCH 1/2] dt-bindings: rng: Document BCM7278 RNG200 compatible

[Florian Fainelli]

BCM7278 includes a RGN200 hardware random number generator, document the
compatible string for that version of the IP.

[PATCH 2/2] hwrng: iproc-rng200: Add support for BCM7278

[Florian Fainelli]

BCM7278 features a RNG200 hardware random number generator block, add
support for this chip by matching the chip-specific compatible string
and extending the Kconfig dependencies to allow building on ARCH_BRCMSTB
(base platform for 7278).
