From 77fb0dc77249891340160063a5c91b2225d2a1be Mon Sep 17 00:00:00 2001 From: Jonathan Santos Date: Wed, 1 Apr 2026 08:58:02 -0300 Subject: [PATCH] dt-bindings: iio: adc: ad4130: Document interrupts property The Data Ready/FIFO interrupt has a special behavior that inverts the IRQ polarity when devices with FIFO support enter FIFO mode, while using normal polarity for data ready. Document the interrupts property to clarify this special behavior for users.
