From 5ded578a18c9515c2c0e1cd148ca42133bbcf055 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 10 Oct 2023 21:42:11 +0200 Subject: rtc: rtc7301: Rewrite bindings in schema This rewrites the Epson RTC7301 bindings to use YAML schema, and adds a property for "reg-io-width" as used in several other bindings to account for different register strides. The USRobotics USR8200 uses the byte IO width.
