Hi Mr. Jonathan and all,=0A=
=0A=
My name is Naidu Tellapati from India. I work for Imagination Technologies,=
India. Thanks in advance for your help in this regard.=0A=
=0A=
After going through some of the emails in the Linux-IIO email archive, we h=
ave taken the following approach to implement our Linux IIO based ADC drive=
r.=0A=
=0A=
We are planning to have two drivers as part of our implementation.=0A=
=0A=
1. Timer's Periodic Interrupt Trigger Provider IIO driver (This driver uses=
our SOC specific Timer's periodic interrupt)=0A=
=0A=
2. The generic IIO ADC driver (This ADC driver uses the periodic Timer Inte=
rrupt Trigger provided by the above driver)=0A=
=0A=
The plan is to push both the drivers upstream to kernel.org. Now please sug=
gest us, do you consider SOC specific Trigger Provider driver as well for p=
ushing upstream to kernel.org ?=0A=

For now just cc'd Lars-Peter on the basis Analog have a very similar timer based trigger (still in staging)
and I suspect he has some thoughts on this.
Lars, want to comment?

The plan for that driver is to replace it with a generic driver that uses
the PWM framework. What we really want from this driver is that it generates
a waveform on a pin which can be used as a conversion start signal.
If you just want to use a timer chip without a PWM waveform write a
clockchip/clocksource driver for your timer IP and then use hrtimer as a
generic IIO trigger. Which brings us back to the old problem that we still
need to create the infrastructure to instantiate hrtimer triggers.
