First thing, very good progress in this driver!

Just for the sake of code / documentation history, this patch, which
adds the driver, should come after patch 2, which adds dt documentation.

So, did I miss something here? Looks like you have extended the of
thermal, and I haven't seen the patch.
  CC [M]  drivers/thermal/rockchip_thermal.o
  drivers/thermal/rockchip_thermal.c: In function
  `rockchip_thermal_register_sensor':
  drivers/thermal/rockchip_thermal.c:482:7: error: too many arguments to
  function `thermal_zone_of_sensor_register'
         rockchip_thermal_set_trips);
