1, the phy support up to 8Mbit/s databitrate for CAN FD.
refer to product data sheet:
https://www.nxp.com/docs/en/data-sheet/TJA1463.pdf
2, the standby pin of the phy is ACTIVE_LOW.
3, the phy of flexcan2 connect the standby/en pin to PCAL6408 on i2c4 bus.

The i.MX 8DualXLite/8SoloXLite has a different connectivity memory map
than the generic i.MX8 has. One conflicting resource is usb, where the
imx8dxl has a second usb2 phy @5b110000, while the generic imx8 dtsi has
one usb2 phy and one usb3 phy, and the usb3otg @5b110000. When
including both imx8dxl-ss-conn.dtsi and imx8-ss-conn.dtsi as done in
imx8dxl.dtsi this leads to a duplicate unit-address warning.
The usb3otg node was introduced after the initial imx8dxl support with
commit a8bd7f155126 ("arm64: dts: imx8qxp: add cadence usb3 support")
and since then leads to warnings like this (when built with W=2):

Fix SD card removal caused by automatic LDO5 power off after boot:
LDO5: disabling
mmc1: card 59b4 removed
EXT4-fs (mmcblk1p2): shut down requested (2)
Aborting journal on device mmcblk1p2-8.
JBD2: I/O error when updating journal superblock for mmcblk1p2-8.
To prevent this, add vqmmc regulator for USDHC, using a GPIO-controlled
regulator that is supplied by LDO5. Since this is implemented on SoM but
used on baseboards with SD-card interface, implement the functionality
on SoM part and optionally enable it on baseboards if needed.
