tpm: Move Linux RNG connection to hwrng

2018-01-08T10:58:36Z

The tpm-rng.c approach is completely inconsistent with how the kernel handles hotplug. Instead manage a hwrng device for each TPM. This will cause the kernel to read entropy from the TPM when it is plugged in, and allow access to the TPM rng via /dev/hwrng.

hwrng: bcm63xx - Remove since bcm2835-rng takes over

2017-11-29T05:43:48Z

bcm2835-rng is now capable of supporting the BCM63xx hardware, so remove the driver which duplicates the same functionality. Signed-off-by: Florian Fainelli Reviewed-by: Eric Anholt Signed-off-by: Herbert Xu

hwrng: bcm2835 - Enable BCM2835 RNG to work on BCM63xx platforms

2017-11-29T05:43:48Z

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.

hwrng: iproc-rng200 - Add support for BCM7278

2017-11-10T11:20:12Z

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). Signed-off-by: Florian Fainelli Signed-off-by: Herbert Xu

hwrng: mx-rngc - add a driver for Freescale RNGC

2017-08-03T06:00:21Z

The driver is ported from Freescale's Linux git and can be found in the vendor/freescale/imx_2.6.35_maintain branch. The driver supports both RNG version C that's part of some Freescale i.MX3 SoCs and version B that is available on i.MX2x chipsets.
