Subject: [PATCH v3 00/10] iio: adc: at91-sama5d2_adc: add support for sama7g5
Date: Wed, 1 Sep 2021 15:30:03 +0300 [thread overview]
Message-ID: <20210901123013.329792-1-eugen.hristev@microchip.com> (raw)
Hi,
This series adds support for sama7g5.
The sama7g5 is slightly different from sama5d2, but has the same basic
operations. The register map is a bit different, so, I added some primitives
to differentiate between the two classes of hardware blocks (sama5d2-sam9x60
and sama7g5).
Sama7g5 has 16 channels ADC, no resistive touch, and extra features
(FIFOs, better oversampling , not implemented yet).
It is a rework of the series initially sent here:
https://marc.info/?l=linux-iio&m=161461656807826&w=2
Changes in v3:
updates for the channel indexes ABI
minor nitpicks fixes
fixed krobot report
Changes in v2:
I reworked this according to review by Jonathan, meaning that first I created
a no-op patch that will convert the driver to a more platform specific data
dedicated type of driver. This adds various structures that hold things like
register layout and channel information.
After this I created few patches that implement the main differences between
sama7g5 and older products: the end-of-conversion new register. I added
helper functions to make code more easy to read and more simple.
One the last patches adds the layout and channels for sama7g5.
At this moment in linux-next, the DT for sama7g5 and sama7g5ek is present,
and the last patches add and enable this node in DT for this board.
