branches: 1.1.2; Rockchip crypto engine RNG driver.
As found on the rk3288 and rk3399. This driver only supports the TRNG, not the rest of the crypto engine, although it uses the AES unit to do a self-test at attach time to verify that the engine works.
There seem to be two versions of the Rockchip crypto engine, v1 and v2; this one is for v1. Can't name a driver `rkcryptov1' so we'll clumsily call it `rkv1crypto' instead to leave room for `rkv2crypto' later on.
The crypto binding derived from the Rockchip BSP Linux kernel, in the location it appears on the rk3399, is in rk3399-crypto.dtsi, since there doesn't seem to be a better place to put it at the moment among this twisty maze of inclusions, all different.
