is to split your driver into a generic drivers/iio/adc/rockchips-tsadc.c
file, and a smaller thermal driver that uses the iio in-kernel interfaces,
ideally one that is independent of the underlying hardware and can
work on any ADC implementation.
such way, that would be great.
from a generic thermal driver to a generic adc driver for the rk3288-tsadc.
I guess the general temperature irq handling would use iio-triggers? But how
does the target temperature get into the TSADC_COMP1_INT register.
Also when getting the temperature, Caesar's driver compares it to its trip
points and sets the next trip point depending on the current temperature
(passive <-> critical) in rockchip_get_temp.
Maybe there is some completely easy way for this, but currently I don't see
thermal, which was posted in February but hasn't been merged.
There may be a newer version of this patch, which I haven't found.
