From 7b34e1e330298cc47985de2e71498ec71f933931 Mon Sep 17 00:00:00 2001 From: Petre Rodan Date: Fri, 29 Dec 2023 11:24:29 +0200 Subject: [PATCH] dt-bindings: iio: pressure: honeywell,mprls0025pa.yaml improvements Define enum inside the honeywell,transfer-function property block. Set the correct irq edge in the example block. Based on the datasheet, in table 13 on page 11: "End-of-conversion indicator: This pin is set high when a measurement and calculation have been completed and the data is ready to be clocked out" Add description on End-of-conversion interrupt.
