Our soc architecture is the loongson2 series, so we will modify it accordingly.

I don't get your point, that dts compatible is "loongson,loongson2-thermal", so this driver file name is named
loongson2-thermal that according what you said about "Filename based on compatible."
If what I understand is not what you expect, please tell me how to modify it.

The loongson2_thermal.c driver need parse this "id" property.

The interrupts of our dts do not specify an interrupt parent,
eg. interrupts = <7 IRQ_TYPE_LEVEL_LOW>
so we need to add an interrupt parent property.

okay, I will have a change.

I refer qoriq platform,
tmu@f0000 {
compatible = "fsl,qoriq-tmu";

You mean to modify it like this
- thermal: thermal@1fe01500 {
+ thermal@1fe01500 {

right ?


Thanks,
