We are using an iMX6S and a TJA1101 as the Ethernet PHY wired for RMII. The Linux kernel is based on 4.9.9 and we are building with Yocto and the rocko branch. Our hardware is not done yet but we are trying to get as much in place as possible before that event. A couple questions I've not found the answer to yet.
Basically, we want to understand the best way to use this phy with the imx6.
Thanks in advance for any advice!
Hi Buster
one can try TJA1101 driver from latest nxp linux L4.14.78_1.0.0
tja110x.c\phy\net\drivers - linux-imx - i.MX Linux kernel
AN12088 Application hints for TJA1100 Automotive Ethernet PHY
https://www.nxp.com/docs/en/application-note/AN12088.pdf
Seems latest i.MX8 processors drivers support it:
linux/arch/arm64/boot/dts/freescale/fsl-imx8qxp-enet2-tja1100.dtsi
fsl-imx8qxp-enet2-tja1100.dtsi\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel
Best regards
igor

Thanks. That was one of the drivers I mentioned (and, in fact, the one I used) so that's helpful.
