Linux driver request for MAX11410 ADC

Question

Hi! 
 Can you provide a Linux driver for MAX11410 and MAX11410A 24-bit ADCs? It has the highest bit resolution and channel amount in SPI ADCs from Maxim integrated, it would be useful to make it. I would like to use and test it in April of 2022.

Hi Livius, 
 obviously you're looking for some 24-bit ADCs. And we're happy to evaluate if we can meet your schedules. 
 The two requests you put in last week we already ordered some HW. However asking for Linux drivers for every 24-bit precision ADC is not going to be helpful since we then won't be able to meet your schedules. 
 The AD4115 might be ok, since we already support this family in the NoOS driver.

 And our SW development team has already some test HW. 
 Ideally you start evaluation of these ADC using the evaluation boards, with the evaluation SW first. 
 I fully understand that this is different from a real Linux driver, but it would allow you to make a preselection. 
 Ideally we support all our converters with devices drivers, however this will take some time and until then we need to prioritize the requests.

There is a PR in process at: https://github.com/analogdevicesinc/linux/pull/1810 This is under heavy review - so the actual code is likely to have some modifications before it is accepted.
