Hello.

We have found the ADF7242 driver which lists you as author. :)

Alexander and myself are working on the linux-wpan subsystem which handles IEEE 802.15.4. It seems the driver was submitted to the old linux-zigbee project (ancestor of linux-wpan, renamed due to not being a zigbee stack) but sadly never made it mainline when other parts have been merged.

Are you still actively working on this driver? Is there an interest from your side to get it into mainline? We would be happy to help you with reviewing it.

So far I have only found these. Are they up to date?

Hi All,

I did tis driver a long time ago, when the Linux 802.15.4 support in general was at its beginning and pretty broken as well. From time to time I update this driver - and actually it's pretty mature - and should apply to mainline without problems.

There is currently only one minor thing that I wanted to investigate (some ifdef in the ISR) before submitting the driver mainline. Are you using the ADF7242 in a design already?
Do you have feedback already?

Best regards,
Michael

Are you using the ADF7242 in a design already?

No. The reason I wrote this is that I have an interest in the linux-wpan subsystem in general and thought the driver would be a good candidate for mainline.

I actually searched for some simple ADF7242which I could hook up to SPI
+ IRQ and maybe some more control lines. So far I only found the official evaluation board which is to expensive for some hobbyist testing.

Quoted 1 line

Do you have feedback already?

The driver interface for ieee802154 has advanced since the it got merged initially. Some of the new things you might want to look into and add support are:

o Async transmit (xmit_async)
o LBT support (set_lbt)
o Set CC mode and ed level (set_cc_mode, set_cca_ed_level)
o Support for monitor mode (set_promiscuous_mode)

These I found missing when having a brief look over the driver.

Well there is the EVAL-ADF7242-PMOD [1] which uses a PMOD [2] interface basically a cheap 100mil spaced header, with SPI, IRQ and supply.

If you are really interested testing the driver I can provide you one FOC.

I see. I have seen that one but was under the impression one needed the mother board for this one as well. As it seems it should be easy to just hookup the PMOD interface to all kind of boards via SPI, IRQ and some more GPIOs.

That is an interesting offer. Alex and myself try to keep a transceiver around for every driver we have in tree, if possible. This helps during review to test the patches as well as testing our own changes which might touch all drivers. Given that Alex does the most work on this right now I would propose to provide him with this board.

Alex, does that sound good to you?

These are not really a must to get the driver merged mainline. But if you find some time working on it before submitting some of these might be easy to add.
