nmaggioni opened a new pull request, #16836:
URL: https://github.com/apache/nuttx/pull/16836

   ## Summary
   
   This PR adds support for the Texas Instruments ADS7046 12-bit, 
SPI-compatible ADC.
   
   The atypical `ANIOC_ADS7046_READ_FASTUNSAFE` ioctl considerably speeds up 
reads in single-threaded environments where the ADC is the only device on the 
assigned SPI bus, at the expense of potential conflicts if used outside these 
conditions.
   
   ## Impact
   
   N/A
   
   ## Testing
   
   These changes were tested on a Linux host, targeting a custom Cortex-M0+ 
(RP2040) board using NuttX v12.8.0 as the baseline. They were then manually 
ported to the current master branch.
