[PATCH v3 1/4] arm64: dts: imx8mq: add Nitrogen8 SoM

From: Lucas Stach <dev@lynxeye.de>
Date: 2021-05-24 12:46:22 

This adds the description of the Nitrogen8 System on Module. The module
is quite simple with only a few (almost) fixed regulators and a eMMC
on-board.

The eMMC is currently limited to 50MHz modes via the pinctrl, as the board
has not wired up the data strobe line, which prevents HS400 mode from
working. As both the controller and the eMMC support this mode, it is
automatically selected when we allow the faster modes, leading to failing
transfers. Until we have a proper solution to only disable HS400 mode,
keep the eMMC at the slow bus modes.

v2:
- remove 100/200MHz pinctrl states for usdhc1
- rename i2c nodes

[PATCH v3 4/4] arm64: dts: imx8mq: add support for MNT Reform2

From: Lucas Stach <dev@lynxeye.de>
Date: 2021-05-24 12:46:23 

This adds a basic devicetree for the MNT Reform2 DIY laptop. Not all
of the board periperals are enabled yet, as some of them still require
kernel patches to work properly. The nodes for those peripherals will
be added as soon as the required patches are upstream.

The following has been tested to work:
- UART console
- SD card
- eMMC
- Gigabit Ethernet
- USB (internal Keyboard, Mouse, external ports)
- M.2 PCIe port

Co-developed-by: Lukas F. Hartmann <redacted>

v2: Fix checkpatch complaints.
v3:
- split out binding
- move status to end of usb node property list
- rename RTC node name to generic name

has not wired up the data strobe line, which prevents HS400 mode from
working. As both the controller and the eMMC support this mode, it is
automatically selected when we allow the faster modes, leading to failing
transfers. Until we have a proper solution to only disable HS400 mode,
keep the eMMC at the slow bus modes.

With the change below, you should be able to keep 100MHz pinctrl state?

I've landed a different change to be able to just disable the HS400
mode and planned to send a follow-on patch using this. As I need to
respin anyways, I'll just fold it in now.
