Subject: [PATCH 11/12] hwrng: bcm2835-rng: Enable BCM2835 RNG to work on BCM63xx platforms
Date: Wed, 1 Nov 2017 18:04:07 -0700 [thread overview]
Message-ID: <20171102010408.27736-12-f.fainelli@gmail.com> (raw)
In-Reply-To: <20171102010408.27736-1-f.fainelli@gmail.com>
We have now incorporated all necessary functionality for the BCM63xx
platforms to successfully migrate over bcm2835-rng, so add the final
bits: Kconfig selection and proper platform_device device type matching
to keep the same platform device name for registration to work.
