Hi,
first of all, thanks for working on this, it will be really cool to see the
crypto accelerator supported in the kernel :-)

as Mark said in the other mail, there may very well follow other Rockchip
crypto-related drivers, so maybe it might be better to name the core
option CONFIG_CRYPTO_DEV_ROCKCHIP. And then maybe define
CONFIG_CRYPTO_DEV_RK3288 in a Kconfig in the subdirectory (like vmx does).

generally, a lot of those subdirectories reference only the manufacturer
name, so my suggestion would be to name yours just "rockchip" instead of
"rk_crypto", to also ease readability.

that looks looks wrong.
(1) the config option does not get defined in any Kconfig file in your set
(2) naming the driver generically while you compile a variant will hinder
multiplatform kernels, because you might want to build both the rk3288
code and some additional stuff?
(3) the _driver suffix is unnecessary
So I guess just name it rk3288_crypto.o ?
[...]
While I have read through the code implementing the device, I haven't
seen anything spring out but do not know enough about the crypto subsystem
itself. But it looks like you got some feedback already anyway from others :-)
Thanks
Heiko
