Subject: "Generic" MMIO ADC
Date: Fri, 30 Jun 2017 10:44:42 +0200 [thread overview]
Message-ID: <b60def9a-45dc-bf97-e059-abbe105648b2@topic.nl> (raw)
I'm writing an IIO driver for a custom IP, which is pretty simple:
- Map the registers to memory and register IRQ routine
- To start acquisition, write a value to the config register
- On interrupt, read data register, push it into queue
- To stop, write another value to config.
Would it be useful to provide this as a generic driver in Linux, so that you
can provide the config register and data register offsets and values in the
devicetree? That would make it work on a lot of similar project without
everyone coding the same thing.
And a related question: Is there a driver that's close to this?
Kind regards,
