cpu: imx8: use intended cpu-thermal device when getting temp value

2020-05-22T11:27:46+00:00

This fixes getting DT alert and critical pdata values in imx_scu_thermal
driver. On i.MX8QXP using not initialized alert pdata value resulted in
boot hang and endless loop outputting:
CPU Temperature (47200C) has beyond alert (0C), close to critical (0C) waiting...

While at it, preset CPU type values once to avoid multiple calls
of device_is_compatible() for same property.

common: Drop net.h from common header

2020-05-18T21:33:31+00:00

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

When current cpu is A53, using is_cortex_a53 could not detect A72
information, so check cpu device compatible property to get
the correct information.
