99638ba9d8 hw/adc: Make adci[*] R/W in NPCM7XX ADC
Our sensor test requires both reading and writing from a sensor's
QOM property. So we need to make the input of ADC module R/W instead
of write only for that to work.

4a84e85413 hw/adc: Fix CONV bit in NPCM7XX ADC CON register
The correct bit for the CONV bit in NPCM7XX ADC is bit 13. This patch
fixes that in the module, and also lower the IRQ when the guest
is done handling an interrupt event from the ADC module.

5ee0abed51 clock: Add ClockEvent parameter to callbacks
The Clock framework allows users to specify a callback which is
called after the clock's period has been updated.  Some users need to
also have a callback which is called before the clock period is
updated.

As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.

Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

77c05b0b74 hw/adc: Add an ADC module for NPCM7XX
The ADC is part of NPCM7XX Module. Its behavior is controled by the
ADC_CON register. It converts one of the eight analog inputs into a
digital input and stores it in the ADC_DATA register when enabled.

Users can alter input value by using qom-set QMP command.
