2020-05-08hwrng: cctrng - change default to nHadar Gat
For many users, the Arm CryptoCell HW is not available, so the default for HW_RANDOM_CCTRNG should to n.

2020-02-22hwrng: imx-rngc - improve dependenciesUwe Kleine-König
The imx-rngc driver binds to devices that are compatible to "fsl,imx25-rngb". Grepping through the device tree sources suggests this only exists on i.MX25. So restrict dependencies to configs that have this SoC enabled, but allow compile testing. For the latter additional dependencies for clk and readl/writel are necessary.

The tpm-rng.c approach is completely inconsistent with how the kernel handles hotplug. Instead manage a hwrng device for each TPM.

2017-04-26s390/trng: Introduce s390 TRNG device driver.Harald Freudenberger
This patch introduces a new device driver s390-trng for the s390 platform which exploits the new PRNO TRNG cpacf subfunction. The true-random-number-generator is accessible from userspace, by default visible as /dev/trng. The driver also registers at the kernel build-in hwrng API to feed the hwrng with fresh entropy data. This generic device driver for hardware random data is visible from userspace as /dev/hwrng.

2017-04-21crypto: exynos - Add new Exynos RNG driverKrzysztof Kozlowski
Replace existing hw_ranndom/exynos-rng driver with a new, reworked one. This is a driver for pseudo random number generator block which on Exynos4 chipsets must be seeded with some value. On newer Exynos5420 chipsets it might seed itself from true random number generator block but this is not implemented yet. New driver is a complete rework to use the crypto ALGAPI instead of hw_random API. Rationale for the change: 1. hw_random interface is for true RNG devices. 2. The old driver was seeding itself with jiffies which is not a reliable source for randomness. 3. Device generates five random 32-bit numbers in each pass but old driver was returning only one 32-bit number thus its performance was reduced. Compatibility with DeviceTree bindings is preserved. New driver does not use runtime power management but manually enables and disables the clock when needed. This is preferred approach because using runtime PM just to toggle clock is huge overhead. Another difference is reseeding itself with generated random data periodically and during resuming from system suspend (previously driver was re-seeding itself again with jiffies).

2015-10-14hwrng: stm32 - add support for STM32 HW RNGDaniel Thompson
Add support for STMicroelectronics STM32 random number generator. The config value defaults to N, reflecting the fact that STM32 is a very low resource microcontroller platform and unlikely to be targeted by any "grown up" defconfigs.

2015-09-21hwrng: Kconfig - Fix device node name reference /dev/hw_random => /dev/hwrngLee Jones
In April 2009, commit d405640 ("Driver Core: misc: add node name support for misc devices.") inadvertently changed the device node name from /dev/hw_random to /dev/hwrng. Since 6 years has passed since the change it seems unpractical to change it back, as this node name is probably considered ABI by now. So instead, we'll just change the Kconfig help to match the current situation. NB: It looks like rng-tools have already been updated.
