concurrent 3-axis data is stored in the FIFO. This patch adds the option
to configure the FIFO to store peak acceleration (x, y and z) of every
over-threshold event. When pushing to iio buffer we push only enabled
axis data.
Currently the driver configures adxl372 to work in loop mode.
The inactivity and activity timings decide how fast the chip
will loop through the awake and waiting states and the
thresholds on x,y,z axis decide when activity or inactivity
will be detected.
This patch adds standard events sysfs entries for the inactivity

within the same sensor. That is why we created extended calibration
which is automatically switched to when object temperature is too high.
This patch also introduces the object_ambient_temperature variable which
is needed for more accurate calculation of the object infra-red
footprint as sensor's ambient temperature might be totally different
than what the ambient temperature is at object and that is why we can
have some more errors which can be eliminated. Currently this temperature
is fixed at 25, but the interface to adjust it by user (with external
sensor or just IR measurement of the other object which acts as ambient),

The change is mostly cosmetic. When looking into the menuconfig help of the

The driver pretty much uses device managed functions. The only left-over is
the iio_device_register() function, which also requires an action-or-reset

staging: mfd: hi6421-spmi-pmic: get rid of interrupt properties
Both irqnum and irqarray properties reflect the same thing:
the number of bits and bytes for interrupts at this
chipset. E. g.:
irqnum = 8 x irqarray
This can be seen by the way pending interrupts are handled:
/* During probe time */
pmic->irqs = devm_kzalloc(dev, pmic->irqnum * sizeof(int), GFP_KERNEL);
/* While handling IRQs */
for (i = 0; i < pmic->irqarray; i++) {
pending = hi6421_spmi_pmic_read(pmic, (i + pmic->irq_addr));
pending &= 0xff;
for_each_set_bit(offset, &pending, 8)
generic_handle_irq(pmic->irqs[offset + i * 8]);
}
Going further, there are some logic at the driver which assumes
that irqarray is 2:
/* solve powerkey order */
if ((i == HISI_IRQ_KEY_NUM) &&
((pending & HISI_IRQ_KEY_VALUE) == HISI_IRQ_KEY_VALUE)) {
generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_DOWN]);
generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_UP]);
pending &= (~HISI_IRQ_KEY_VALUE);
}
As HISI_IRQ_KEY_DOWN and HISI_IRQ_KEY_UP are fixed values
and don't depend on irqnum/irqarray.
The IRQ addr and mask addr seem to be also fixed, based on some
comments at the OF parsing code. So, get rid of them too,
removing the of parsing function completely.
