This patch series adds fixes and improvements in the ad7124 driver.
Fixes:
- properly compare config values
- add a delay after reset to allow chip initialization
Improvements:
- reduce the number of SPI transfers
- ensure that after probe the ADC is in idle mode
and not continuos conversion mode
Another thing that could be considered is improving the config pop
behavior as kfifo_get() will return the least recently added config
instead of the least recently *used* one.
This could be an issue when multiple channels are using the same "old"
config and the LRU considers that one as the least recently used.
If this is considered a valid issue, I can add another patch for it.
