Request for Driver Support for Multiple Modules

A_VIJAYA7 — Fri, 27 Jun 2025 11:09:43 GMT

Dear NXP Support Team,

We are currently working with S32RDB3 reference board, several modules listed below and have identified that drivers for some of them are not available in the BSP driver package. Kindly assist us with the availability or development support for the following:

Modules without drivers:

LIN Transceiver (TJA1124HG/1Z)
LIN Controller (SJA1124HG/1Z)

ADC (AD7490BCPZ)

Potentiometer (DS3930E)
MUX (CD4052B)
Driver files available for some modules:

gpio-pca953x.c
phy-can-transceiver.c
Please let us know if there are any updates or alternative solutions.

Hello @A_VIJAYA7,

Thanks for reaching out to us. Please find my answers to your question:

TJA1124
- For this part, no driver is needed, since it works only as a transceiver, in fact the RDB3 includes one of this.
- Please check section 12 LLCE Support in particular, subsection 12.5 LINFlexD, as it describes the use and modifications needed to use it.
- Please note that our BSP, only supports UART mode, not LIN mode. Are you planning to use it in UART mode or LIN mode?
SJA1124
- As you mentioned, we do not offer a driver for that device.
AD7490BCPZ, DS3930E, CD4052B.
- These components are not provided by NXP, therefore there is no plan to add them into the BSP.
  - For the ADC I was able to find this driver, which is a newer ADC by the same manufacturer: ad7091r-base.h
  - For the other devices I was not able to find any code reference.
gpio-pca953x.c, phy-can-transceiver.c
- in this files you can see that they were developed by Marvell and Texas instruments respectively.

My recommendation for AD7490BCPZ, DS3930E and CD4052B is to reach out to their respective manufacturers and ask if there is any Linux driver already developed by them.

For SJA1124, you can reach out to your FAE/NXP representative and request a feature added into our BSP. You could request the same for AD7490BCPZ, DS3930E and CD4052B, but I would recommend to reach out to the respective manufacturers first.

Let me know if you have more questions related to this topic.
