Hi,
We need to support rk3036 soc platform via upstream, there are
some primary parts for the initial release of minimum system: dts,
clk-pll, smp, and clock tree for rk3036, and additional, we can use
these startup and run to init processs.
Thanks.
Changed in v6:
- add hardware timer in dtsi
The rk3036's pll and clock are different with base on the rk3066(rk3188,
rk3288, rk3368 use it), there are different adjust foctors and control
registers, so these should be independent and separate from the series
of rk3066s.

We still need to agree on the user space interface which is the
In case we monitor events system wide, we get EXIT event
(when configured) twice for each task that exited.
Note doubled lines with same pid/tid in following example:
$ sudo ./perf record -a

VXLAN may be a loadable module, and this driver cannot be built-in
in that case, or we get a link error:
drivers/built-in.o: In function `__bnxt_open_nic':
drivers/net/ethernet/broadcom/bnxt/bnxt.c:4581: undefined reference to
`vxlan_get_rx_port'
This adds a Kconfig dependency that ensures that
