Beside regular feed control interrupt, the driver requires also hash interrupt for older SoCs (samsung,s5pv210-secss). However after requesting it, the interrupt handler isn't doing anything with it, not even clearing the hash interrupt bit. Driver does not provide hash functions so it is safe to remove the hash interrupt related code and to not require the interrupt in Device Tree.

|
|
|
|
The SSS module in S5PV210 SoC supports the following:
|
|
-- Feeder (FeedCtrl)
|
|
-- Advanced Encryption Standard (AES)
|
|
-- Data Encryption Standard (DES)/3DES
|
|
-- Public Key Accelerator (PKA)

-- SHA-1/SHA-256/MD5/HMAC (SHA-1/SHA-256/MD5)/PRNG
|
|
-- PRNG: Pseudo Random Number Generator
|
|
|
|
The SSS module in Exynos4 (Exynos4210) and
|
|
Exynos5 (Exynos5420 and Exynos5250) SoCs
|
|
supports the following also:
|
|
-- ARCFOUR (ARC4)
|
|
-- True Random Number Generator (TRNG)
|
|
-- Secure Key Manager
|
|
|
|
Required properties:
