Subject: [PATCH v1 0/3] hwrng: add hwrng support for Rockchip RK3568
Date: Sat, 12 Nov 2022 15:10:56 +0100	[thread overview]
Message-ID: <20221112141059.3802506-1-aurelien@aurel32.net> (raw)

Rockchip SoCs used to have a random number generator as part of their
crypto device, and support for it has to be added to the corresponding
driver.

However newer Rockchip SoCs like the RK3568 have an independent True
Random Number Generator device. This patchset adds a driver for it and
enable it in the device tree.

Aurelien Jarno (3):
  dt-bindings: RNG: Add Rockchip RNG bindings
  hwrng: add Rockchip SoC hwrng driver
  arm64: dts: rockchip: add DT entry for RNG to RK356x
