From a3e36525a9b853c09d5f5726eff3641cd0cb5619 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Mon, 6 Jul 2020 22:01:17 +0200 Subject: [PATCH] rtc: i2c_rtc_emul: catch any write to the "reset" register It's more natural that any write that happens to touch the reset register should cause a reset, rather than just a write that starts at that offset.
