Because otherwise, you are asking to merge duplicated code. There's a generic way to define thermal zones, trip points, cooling devices, etc. And also code to parse and plug them together. Why add soc-specific code to do the same? > I believe omap,tegar and rockchip are the three seperate thermals driver. Yes, and OMAP is already using the generic bindings, and the proposed patches for Tegra as well, and I think it would make sense for Rockchip to also use them (unless I'm missing something).

You are talking about drivers/thermal/of-thermal.c, right? Yes, I think Rockchip should be using the same generic framework if possible. Thanks.
