From fdaf4c5acf268bfcc455d8c2ab775cd54317c788 Mon Sep 17 00:00:00 2001 From: Javier Carrasco Date: Thu, 14 Sep 2023 11:07:59 +0200 Subject: dt-bindings: rtc: pcf2123: convert to YAML Convert the existing txt binding to the preferred YAML format. The pcf2123 node may contain SPI settings such as spi-cs-high and spi-max-frequency, which keeps it from being added to the trivial-rtc binding with its current definition. Add a reference to spi-peripheral-props.yaml to account for that. The "interrupts" property was missing in the binding although it is already supported. Add the missing property in the new binding.
