[src/trunk]: src/sys/arch/arm/rockchip mostly port to rk3328.
details: https://anonhg.NetBSD.org/src/rev/5192e225bc23
branches: trunk
changeset: 451289:5192e225bc23

description:
mostly port to rk3328.
- add rk3328 data<->temp table, and adjust code to use this vs rk3399
table for rk3328. add support for decrementing data.
- adjust auto period times for rk3328 vs rk3399
- add min/max data values, if data is outside these values mark the
sensor invalid.
- move init code into cpu specific sections, add rk3328 support
with a rk3328_cru.c update to add clocks, this attaches and reports
garbage values, so for now it's disabled.
