Can you help me understand how these two files are related?  Why is
sgtl5000 added into one and sound node added into the other?

Same question here: why is sgtl5000 added to imx6ul-geam-kit.dts, while
sound code that references to sgtl5000 is added to imx6ul-geam.dtsi?

Why cannot you just add sgtl5000 node into dtsi rather than keeping the
same copy for 4 dts files?

lcdif, ts and sound card which may differ based on the base-board
connected with SOM, So I moved these stuff which are related to
Starter kit supported once's and used with SOM dts files. if some
other board with same SOM can have different lcdif and etc so they can
define locally to dts.

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?

isiot is a modules class, with that emmc and nand are two separate
SOM's. the current support is for mounting these SOM's on Development
base board[1]. 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

So you are not sure if imx6ul-isiot-common.dtsi will be used by carrier
board.  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?

So,even the common stuff (lcdif, ts and etc) should be in -isiot.dtsi
and make it "disabled" and let them enabled on respective dts. this
what you mentioned here?

Yes, anything common can be in -isiot.dtsi.

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.

OK, thanks for the help. I'll resolve and send v4 changes by breaking
this series for each respective modules.
