Hello, here is a patchset updating the existing max1027.c driver (for 10-bit max1027/29/31 ADCs) with a few corrections/improvements and then introducing their 12-bit cousins named max1227/29/31. As on my hardware setup the "start conversion" and "end of conversion" pin are not wired (which is absolutely fine for this chip), I also updated the driver and the bindings to support optional interrupts. In this case, triggered buffers are not available and the user must poll the value from sysfs. Thanks, Miquèl Changes in v2: ============== * Removed the addition of three compatibles from patch 4 (the preparation patch) to add these lines back in patch 5 (the actual introduction).
