Add support for audio-codec NAU88C22 present on the Apalis Evaluation
Board v1.2 carrier board.
Upstream-Status: Pending
- This change depends on audio being supported on mainline for
iMX8QM/QP, which is not working yet.

Add support for the new version, v1.2, of Apalis Evaluation Board with
Apalis iMX8 v1.1 QP module.
Board versions v1.0 and v1.1 are compatible with each other and should
use imx8qp-apalis-v1.1-eval.dts file dts file.
Upstream-Status: Inappropriate [other]
- Apalis iMX8 QP has no specific device tree file mainline, there the
device file for iMX8 QM is used.

Add support for the new version, v1.2, of Apalis Evaluation Board.
Because only imx8-apalis-eval.dtsi was available and used as the only
board configuration for board version v1.0 and v1.1, it was changed to
be the common hardware configurations for all versions v1.0,
v1.1 and v1.2. Also, two .dtsi board files were added to have the
differences by board. The .dts were organized by SoM and board version.
Board versions v1.0 and v1.1 are compatible with each other and should
use imx8qm-apalis-eval.dts file or imx8qm-apalis-v1.1-eval.dts file
depending on SoM version. Now for v1.2, organized by SoM version too, the
files are imx8qm-apalis-eval-v1.2.dts and imx8qm-apalis-v1.1-eval-v1.2.dts.

The Verdin iMX8M Mini System on Module does not have USB-ID signal
connected on Verdin USB_2 (usbotg2). On Verdin Development board this is
no problem, as we have connected a USB-Hub that is always connected.
However, if Verdin USB_2 is desired to be used as a single USB-Host port
the chipidea driver does not detect if a USB device is plugged into this
port, due to runtime pm shutting down the PHY.
Add the power-domain &pgc_otg2 to &usbphynop2 in order to detect
plugging events and enumerate the usb device.

The GPIO signaling ctrl_sleep_moci is currently handled as a gpio hog.
But the gpio-hog node is made a child of the wrong gpio controller.
Move it to the node representing gpio4 so that it actually works.

The current verdin imx8mm device tree sets up the maximum SPI clock of
the MCP2518FD CAN controller to 2Mhz. After executing tests with real
CAN bus traffic, customers noticed significant packet loss (in some
cases higher than 30% of packets lost). With more testing, we found out
that increasing the SPI clock reduces the packet loss significantly
without noticeable negative impact. The tests were performed with 3
different bus rates (256kbps, 512kbps and 1Mbps) and 3 different CAN bus
occupation rates (~30%, ~55% and ~100%).
To select the SPI clock rate for this change, we considered an errata
for the MCP2518FD chip that states that the RAM can be corrupted when
written at high SPI clock speeds while there's simultaneous activity on
the CAN bus. The listed workaround for this issue is to limit the SPI
clock to 0.85 * (SYSCLK/2). On the verdin imx8mm we have the SYSCLK setup
in the hardware as 20MHz. This commit changes the SPI clock frequency to
8.5 Mhz so that we get the best performance out of the hardware.
With this change we can measure reduced packet loss in several
conditions, according to the table (all the tests executed with DLC 1):
+-------------+----------------+------------------+--------------------+
| Bus bitrate | Bus occupation | Packet Loss 2Mhz | Packet Loss 8.5Mhz |
+-------------+----------------+------------------+--------------------+
| 1Mbps | 57 % | 33.92 % | 0 |
+-------------+----------------+------------------+--------------------+
| 500kbps | 57 % | 12.03 % | 0 |
+-------------+----------------+------------------+--------------------+
| 1Mbps | 100 % | 31.68 % | 4.1 % |
+-------------+----------------+------------------+--------------------+
| 500kbps | 100 % | 32.66 % | 0.2 % |
