2018-03-23crypto: inside-secure - fix clock resource by adding a register clockGregory CLEMENT
On Armada 7K/8K we need to explicitly enable the register clock. This clock is optional because not all the SoCs using this IP need it but at least for Armada 7K/8K it is actually mandatory. The binding documentation is updated accordingly. Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2018-03-23crypto: inside-secure - improve clock initializationGregory CLEMENT
The clock is optional, but if it is present we should managed it. If there is an error while trying getting it, we should exit and report this error. So instead of returning an error only in the -EPROBE case, turn it in an other way and ignore the clock only if it is not present (-ENOENT case).

2018-03-23crypto: inside-secure - fix clock managementGregory CLEMENT
In this driver the clock is got but never put when the driver is removed or if there is an error in the probe. Using the managed version of clk_get() allows to let the kernel take care of it.

2018-03-03crypto: ccp - return an actual key size from RSA max_size callbackMaciej S. Szmigiero
rsa-pkcs1pad uses a value returned from a RSA implementation max_size callback as a size of an input buffer passed to the RSA implementation for encrypt and sign operations. CCP RSA implementation uses a hardware input buffer which size depends only on the current RSA key length, so it should return this key length in the max_size callback, too. This also matches what the kernel software RSA implementation does. Previously, the value returned from this callback was always the maximum RSA key size the CCP hardware supports. This resulted in this huge buffer being passed by rsa-pkcs1pad to CCP even for smaller key sizes and then in a buffer overflow when ccp_run_rsa_cmd() tried to copy this large input buffer into a RSA key length-sized hardware input buffer.
