[PATCH 0/3] hw_random: bcm2835: Add support for Broadcom BCM5301x

[Florian Fainelli]

Hi all,

This patch series adds support for the Broadcom BCM5301x SoCs random number
generator which is the same block as the one found in NSP and BCM2835.

[PATCH 2/3] hw_random: bcm2835: Add support for Broadcom BCM5301x

[Florian Fainelli]

The Broadcom BCM5301x SoCs (Northstar) utilize the same random number
generator peripheral as Northstar Plus and BCM2835, but just like the
NSP SoC, we need to enable the interrupt.

Thanks! Do you mind taking patch 1 as well? I will take patch 3 via my
arm-soc tree.
