The reMarkable2 (https://remarkable.com) is an e-ink tablet based on
the imx7d SoC.
This commit is based on the DTS provide by reMarkable but ported to the
latest kernel (instead of 4.14). I have removed references to
non-upstream devices and have changed the UART so that the console can
be accessed without having to open up the device via the OTG pogo pins.
Currently the kernel boots, but there is no support for the dispaly,
WiFi or the power controller chips.

Just out of curiosity, this is a DIY cable or something generally
available from vendor?

There are still some WiFi related devices. Can we drop all those
untested stuff?

The new compatible needs to be documented. Also the compatible doesn't
look right, as this is a device from reMarkable rather than FSL.

We can leave it to future updates on the defconfig.

I need to do something across all our defconfigs at some point, but I want
to be done more thoroughly:
For any option or group of options that disappears from a defconfig file, I
want to see one patch (ideally across all such files) that explains why
the option that used to be intentionally enable is no longer there. If it
got renamed or replaced by something else, that should be set instead.
If there is a new dependency, we may need to enable that in addition
to the old option, rather than dropping it silently.
For options that just move around in the file, I would group them in
a final cleanup patch.

It's a DIY cable, it's a bit of a pain to put together. You can see
what it looks like here: https://github.com/ddvk/remarkable2-recovery

I have WiFi working on the 5.4 NXP branch. I was actually thinking
that WiFi should just work if the rootFS and FW all match. The main
problem is that the kernel expects a firmware version that isn't in
linux-firmware.
I have removed it for now though.
