ARMv8.2 specifies special instructions for the SM3 cryptographic hash
and the SM4 symmetric cipher. While it is unlikely that a core would
implement one and not the other, we should only use SM4 instructions
if the SM4 CPU feature bit is set, and we currently check the SM3
feature bit instead. So

These drivers don't have a probe() callback.

Hi,
I'm resending patch series, as I forgot to CC linux-crypto list.
This patch series fixes/improves CAAM JR dependent drivers initialization.
So far successful initialization depended on link and device-tree nodes
order. These changes make sure all drivers that use JRs (i.e. call

It is possible, that caam_jr_alloc() is called before JR devices are
probed. Return -EPROBE_DEFER in drivers that rely on JR devices, so
they are probed at later stage.

There is a race condition, when driver is not initialized
yet (jr_driver_init() was not called yet), but another kernel
code calls caam_jr_alloc(). This results in warnings about
uninitialized lock and NULL pointer dereference error.
Fix that by statically initializing global driver data, so
