This patchset contains:
- i.MXRT10xx family infrastructure
- i.MXRT1050 pinctrl driver adaption
- i.MXRT1050 clock driver adaption
- i.MXRT1050 sd-card driver adaption
- i.MXRT1050 uart driver adaption
- i.MXRT1050-evk basic support

The i.MXRTxxxx family that could have support by Linux actually spreads
from i.MXRT1020 to i.MXRT1170 with the first one supporting 1 USB OTG &
100M ethernet with a cortex-M7@500Mhz up to the latter with i.MXRT1170
with cortex-M7@1Ghz and cortex-M4@400Mhz, 2MB of internal SRAM, 2D GPU,
2x 1Gb and 1x 100Mb ENET. The i.MXRT family is NXP's answer to
STM32F7XX, as it uses only simple SDRAM, it gives the chance of a 4 or
less layer PCBs. Seeing that these chips are comparable to the
STM32F7XXs which have linux ported to them it seems reasonable to add
support for them.

I'm in the process of finalizing the pull requests for 5.16, this came
up since you
have soc@kernel.org on Cc, but it looks like you don't have an Ack for the
clock driver, and I have not heard from Shawn or Sasha about whether they
want to pick it up in a separate branch or I should pick it up.

I suggest we leave it for this time then, let's plan for 5.18 instead.
