device_imx.h duplicated and put in 2 locations. Is there a common place we can add this file?

[mmahadevan108]

@mcuxsusan. Any thoughts on avoiding device_imx.h duplication?

[mcuxsusan]

Hi @mmahadevan108 , sorry for my late response. Per my understanding, this device_imx.h header file is similar as our fsl_device_registers.h, just used to include the needed header file for this specific device. So, I was wondering we should have individual device_imx.h, just like our fsl_device_registers.h.

I could make the content only specified for this device, is that acceptable for your side?

[mmahadevan108]

I think that should work. Thank you

@mcuxsusan Getting back to this PR. Can it be update per the above discussion.

@mmahadevan108, please check the updated PR, thanks a lot.

@mcuxsusan , restarting this thread as there are some PR's in Zephyr that could benefit from adding this support in the SDK. Does this PR need to be updated for the current version of the SDK?

[mcuxsusan]

Hello @mmahadevan108, checking with the NPI team, these two devices are not in SDK support scope now. So, we are not able to add the two devices into the mcux-sdk repo. Not sure if you would like to have these two devices support maintain in hal_nxp.
