8c07f7653a The DTS may report fewer than 4 parents for a module clock. Avoid setting 
the module clock parent to an out-of-range index in these cases.

bd95d8610a Fix H3 temperature reporting. The formula in for V1.0 of the H3 datasheet 
seems to be incorrect, so use the same method of conversion as the H3 BSP
instead.

a6e9118bf4 Add support for Allwinner Consumer IR interface. 
RX is supported now and the driver is using evdev framework.
It was tested on Cubieboard2 (A20 SoC) using lirc
with dfrobot's IR remote controller.

3c2b90f1d1 Throttle CPU frequency when hot temperature threshold has been reached to

d3bf5efc1f Fix device delete child function. 
When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().

Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.

While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

1834282de6 Split CPU_CORTEXA into CPU_CORTEXA8, for the Cortex-A8, and CPU_CORTEXA_MP, 
for later Cortex-A CPUs that support the Multiprocessor Extensions. This
will be needed to support both in a single GENERIC kernel while still
being able to only build for a single SoC.

Rename registers as in the manual.

to differentiate SoC as the fdt compatible string were the same.
