I do not follow how these stuff are organized. So far we have the following isiot dts files. - imx6ul-isiot-common.dtsi - imx6ul-isiot.dtsi - imx6ul-isiot-emmc.dts and imx6ul-isiot-nand.dts How are they mapping to SoM and base-board? Shawn

So, for isiot module class we have imx6ul-isiot.dtsi and emmc and nand SOM's have imx6ul-isiot-emmc.dts and imx6ul-isiot-nand.dts. There are some Carrier boards[1] which were used with different lcdif and other changes, So imx6ul-isiot-common.dtsi have changes common across emmc and nand, instead of adding them into individual dts files I moved in -common.dtsi. So in future if isiot SOM mounted on carrier board which should have a separate dts and which may or may not use imx6ul-isiot-common.dtsi [1] https://www.engicam.com/vis-prod/101142 [2] https://www.engicam.com/vis-prod/101128 thanks! -- Jagan Teki Senior Linux Kernel Engineer | Amarula Solutions U-Boot, Linux | Upstream Maintainer Hyderabad, India.

Then what's the point to have it now? You are saying imx6ul-isiot-common.dtsi is created to accommodate the common things across emmc and nand SoMs, but it actually contains LCD and Touch such base-board level of stuff. Confusing. I feel the abstraction is wrong from the beginning. Ideally, we should have something like below. - imx6ul-isiot.dtsi - imx6ul-isiot-kit.dts and imx6ul-isiot-carrier.dts The -isiot should have everything on SoM and common stuff between -kit and -carrier boards, while -kit and -carrier include -isiot and contains the base-board specific things. The -isiot can have both emmc and nand devices with "disabled" status, and let firmware turn device on per SoM it boots. In that case, the abstraction level can be less and clearer. Thoughts? Shawn

It doesn't matter. If the lcd/touch is same on -kit and -carrier, you can even have them enabled by default in -isiot.dtsi. The -kit.dts and -carrier.dts are there to accommodate base-board specific differences. Shawn

OK, thanks for the help. I'll resolve and send v4 changes by breaking this series for each respective modules. thanks! -- Jagan Teki Senior Linux Kernel Engineer | Amarula Solutions U-Boot, Linux | Upstream Maintainer Hyderabad, India.
