PRNG Block on most of newer target from Qualcomm have some

Adding separate compatible string for each platform is overhead.
We need to introduce common compatible string that can be used for
all platforms with same configuration.
I would suggest to use "qcom,rng-ee" for newer platform, dropping
"p" also signifies it is not a Pseudo Random Number Generator.
Please reply inline and don't top-post.
Is this what you're trying to say?
1. sort out the clock requirements for designs where Linux manages it
vs where the FW does so >
2. introduce a new compatible for SoCs implementing a TRNG
3. for SoCs in 2., register the TRNG as a hwrng device
Yes to all
I can send a proposal, but that means writing a new driver for this
compatible in drivers/char/hw_random/ right ?
We can add hwrng support in same driver like
drivers/crypto/hisilicon/trng/trng.c
As Krzysztof is suggesting we need to have platform specific compatible
string, we can go with your change. for hwrng support I will send
separate patches.
