AM5728: adding I2C Slave driver in device tree

Tia Basak

Part Number: AM5728

Hello,

I understand that the Ti sdk doesn't have the slave code for the am5728. I have added a patch that was given to me by ti some time ago. I was wondering how to you add an I2C slave to the device tree. So far I have added a child node, and the slave address, but do I need to change something in the i2c-omap.c code as well? Do I need to add a i2c slave driver?

Please let me know thank you!

Hi Tia,

I believe you have already referred: https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Foundational_Components/Kernel/Kernel_Drivers/I2C.html

Yes there is no slave support for i2c controller. I have a question here do you want to connect
a slave device to omap i2c or you want omap i2c as a slave?

For 1) You can refer the PMIC (tps659038) which acts as a slave to omap i2c you can check in am57* dts files under arch/arm/boot/dts folder.
For 2) No such ready code available.

Best Regards,
