Since, CAAM driver is probed before soc_device_attribute done as part of:
- drivers/soc/imx/soc-imx8m.c (for i.MX8M)
- drivers/firmware/imx/ele_mu.c (EdgeLock Enclave kernel driver, for i.MX8ULP)
It is needed to return -EPROBE_DEFER, after calling soc_device_match() in
drivers/crypto/caam/ctrl.c.
soc_device_match returns NULL for:
- i.MX8M
- i.MX8ULP,
can be considered that the SoC device has not been probed yet.
Hence, it returns -EPROBE_DEFER directly.
caam: imx: change to use of_match_node in run_descriptor_deco0
Providing imx8m_machine_match to match:
- i.MX8M{Q,M,N,P},
- i.MX8ULP,
so as to start using of_match_node, to simplify the code.
