what are these [1] and [2] references? Probably there might be some links.

- SIM Slot for Modem
- Debug connectors
- 6x On-Board LEDs

Please change the order of i2c3 and i2c6.

May be put the clock above after &pcie1_phy like in the list of gcc
source clocks?

+&pcie0 {

+ perst-gpios = <&tlmm 94 GPIO_ACTIVE_LOW>;

+ vdda-qref-supply = <&vreg_l1i_0p88>;

So I've found just these minor things, and I've successfully tested
the dtb on the SM8650-HDK board.
