[PATCH V3 1/3] crypto: caam: Add support for i.MX8M Mini

From: Adam Ford <hidden>
Date: 2019-12-18 13:06:30
Also in: linux-crypto, linux-devicetree, lkml
Subsystem: crypto api, freescale caam (cryptographic acceleration and assurance module) driver, the rest · Maintainers: Herbert Xu, "David S. Miller", Horia Geantă, Pankaj Gupta, Gaurav Jain, Linus Torvalds

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.

V3:  No Change
V2:  Expand the check that forces the setting on imx8mq to also be true for imx8mm
     Explictly state imx8mm compatiblity instead of making it generic to all imx8m*
      this is mostly due to lack of other hardware to test
