crypto: caam - add support for i.MX8M Plus

2020-01-22T08:21:11+00:00

Add support for the crypto engine used in i.mx8mp (i.MX 8M "Plus"),
which is very similar to the one used in i.mx8mq, i.mx8mm, i.mx8mn.

crypto: caam - add support for i.MX8M Nano

2020-01-16T07:18:13+00:00

Add support for the crypto engine used in i.mx8mn (i.MX 8M "Nano"),
which is very similar to the one used in i.mx8mq, i.mx8mm.

Since the clocks are identical for all members of i.MX 8M family,
simplify the SoC <--> clock array mapping table.

crypto: caam - Add support for i.MX8M Mini

2019-12-27T10:18:03+00:00

The i.MX8M Mini uses the same crypto engine as the i.MX8MQ, but
the driver is restricting the check to just the i.MX8MQ.

This patch expands the check for either i.MX8MQ or i.MX8MM.

crypto: caam - do not reset pointer size from MCFGR register

2019-12-11T08:36:45+00:00

In commit 'a1cf573ee95 ("crypto: caam - select DMA address size at runtime")'
CAAM pointer size (caam_ptr_size) is changed from
sizeof(dma_addr_t) to runtime value computed from MCFGR register.
Therefore, do not reset MCFGR[PS].

crypto: caam - populate platform devices last

2019-11-01T05:38:31+00:00

Move the call to devm_of_platform_populate() at the end of
caam_probe(), so we won't try to add any child devices until all of
the initialization is finished successfully.
