According to the documents, the i.MX8M-Mini features a GC320 and a
GCNanoUltra GPU core. Etnaviv detects them as:

	etnaviv-gpu 38008000.gpu: model: GC520, revision: 5341

This seems to work fine more or less without any changes to the HWDB,
which still might be needed in the future to correct some features,
etc.

The internal Ethernet switch suffers from erratum A-050484 ("Ethernet
flow control not functional on L2 switch NPI port when XFH is used").
XFH stands for "Extraction Frame Header" - which basically means the
default "ocelot" DSA tagging protocol.

However, the switch supports one other tagging protocol - "ocelot-8021q",
and this is not subject to the erratum above. So describe the hardware
ability to pass PAUSE frames in the device tree, and let the driver
figure out whether it should use flow control on the CPU port or not,
depending on whether the "ocelot" or "ocelot-8021q" tagging protocol is
being used.

In linux both are identical, phy-mode is used more often, though. Also
for the ls1028a both phy-connection-type and phy-mode was used, one for
the enetc nodes and the other for the switch nodes. Unify them. But the
main reason for this is that the device tree files can be shared with

The NXP BlueBox3 is a prototyping board for high-performance autonomous
driving systems. It contains two Linux systems, running on the
LX2160A and the other on the S32G2 SoC. This patch adds the device tree
support for the LX2160A SoC.

In terms of networking from the LX2160A's perspective, there are:

- 4 RJ45 10G ports using Aquantia copper PHYs which are attached
  directly to DPAA2 ports on the LX2160A

- 3 NXP SJA1110 automotive Ethernet switches. First two are managed by
  the LX2160A (each switch has a host port towards a dpmac), the third
  switch is managed by the S32G2. All 3 switches are interconnected
  through on-board SERDES lanes. The cascade ports between the 2
  switches managed by LX2160A form a DSA link, the cascade ports between
  the LX2160A and the S32G2 domain form user ports (the "to_sw3" net
  device).

- 2 RJ45 1G ports using Atheros copper PHYs which are attached directly
  to NXP SJA1110 switches

- 12 automotive 100base-T1 single-pair Ethernet ports routed from the
  SJA1110 internal PHY ports (TJA1103)

- One SGMII SERDES lane towards an internal connector, attached to one
  of the SJA1110 switch ports

On board rev A, the AR8035 RGMII PHY addresses were different than on
rev B and later. This patch introduces a separate device tree for rev A.
The main device tree is supposed to cover rev B and later.

The conversion of the spi-imx driver to use GPIO descriptors
in commit 8cdcd8ae ("spi: imx/fsl-lpspi: Convert to GPIO descriptors")
helped to detect the following SPI chipselect polarity mismatch on an
imx6q-sabresd for example:

[    4.854337] m25p80@0 enforce active low on chipselect handle

Prior to the above commit, the chipselect polarity passed via cs-gpios
property was ignored and considered active-low.

The reason for such mismatch is clearly explained in the comments inside
drivers/gpio/gpiolib-of.c:

* SPI children have active low chip selects
* by default. This can be specified negatively
* by just omitting "spi-cs-high" in the
* device node, or actively by tagging on
* GPIO_ACTIVE_LOW as flag in the device
* tree. If the line is simultaneously
* tagged as active low in the device tree
* and has the "spi-cs-high" set, we get a
* conflict and the "spi-cs-high" flag will
* take precedence.

To properly represent the SPI chipselect polarity, change it to active-low
when the "spi-cs-high" property is absent.
