The panel connects with the QSB board through an adapter board[1]
designed by NXP.

Can you add some description about raname in commit message?
Use -C option to create patch.

Is it possible to appply this overlay file and kd50g21-40nt-a1 overlay file

to imx93-9x9-qsb.dtb, so needn't create dtsi.

I'll add some description about the file copy in commit message.

Will do.

I'm sorry, I don't get your question here.
Anyway, the DT overlays are needed, because the 40-pin EXP/PRI interface on
the i.MX93 9x9 QSB board can not only connect to a DPI panel adapter board
but also to an audio hat[2], and maybe more.  The newly introduced .dtsi
file just aims to avoid duplicated code.

My means apply two overlay files to dtb

imx93-9x9-qsb-tianma-tm050rdh03-dtbs += imx93-9x9-qsb.dtb imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtbo imx93-9x9-qsb-tianma-tm050rdh03.dtbo

In imx93-9x9-qsb-tianma-tm050rdh03.dtbo, only include
&{/} {
	panel {
		compatible = "tianma,tm050rdh03";
		enable-gpios = <&pcal6524 8 GPIO_ACTIVE_HIGH>;

If an user wants to use imx93-9x9-qsb.dtb and the DT overlay blob
imx93-9x9-qsb-tianma-tm050rdh03.dtbo to enable the tianma,tm050rdh03
DPI panel, then it won't work unless the user also apply
imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtbo, right?

Yes, imx93-9x9-qsb-tianma-tm050rdh03.dtb already created, which already
applied both overlay file.

can the same board be use for imx91 or other evk boards?

.... indicates that imx93-9x9-qsb-tianma-tm050rdh03.dtb is generated by
applying both imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtbo and
imx93-9x9-qsb-tianma-tm050rdh03.dtbo to imx93-9x9-qsb.dtb.
While, imx93-9x9-qsb-tianma-tm050rdh03.dtbo(a DT overlay blob) just contains
the panel node, which means that an user __cannot_ enable the tianma,tm050rdh03
DPI panel by only applying it to imx93-9x9-qsb.dtb, unless the user also
applies imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtbo.  That's why the .dtsi
file is needed.

Yes, both tianma,tm050rdh03 and ontat,kd50g21-40nt-a1 DPI panels can be
connected to i.MX91/93 11x11 EVK and 9x9 QSB boards.

what's problem if we require user do that? Makefile already create finial

Is it possible to use one overlay files for all imx91/imx93 boards?
