  soc: imx: Add i.MX8MN SoC driver support (2019-06-24 09:15:57 +0800)

----------------------------------------------------------------
i.MX driver changes for 5.3:
 - Add i.MX SCU based SoC bus driver for i.MX8QXP SoC support, which
   talks to SCU firmware for getting SoC ID and revision.
 - Update soc-imx8 bus driver to read imx8mm soc revision from anatop.
 - Add i.MX8MN SoC bus support into soc-imx8 driver.
 - Various small improvements on soc-imx8 bus driver.

Given that these were posted at the same time, it seems silly to post a patch
with a fix right after -- they should probably be squashed before sending out
(or when applying).


Anyway, minor nit. Merged the branch.


Thanks!

Hmm, soc-imx-scu is the new SoC bus driver added during this development
cycle, but all those improvements are around soc-imx8 driver which
landed on 5.2 release.

Thanks, Olof.
