From 04d8cc3514c3da3e3790d56417e0b0d6420d56df Mon Sep 17 00:00:00 2001 From: Werner Zeh Date: Thu, 22 Jul 2021 14:51:26 +0200 Subject: [PATCH] mb/siemens/mc_ehl: Add external RTC RX6110SA All the mainboards based on mc_ehl use the external RTC RX6110SA. Enable the driver in Kconfig for all boards based on mc_ehl. In addition, as mc_ehl1 has the RTC attached to the SMBus, add the devicetree entry on behalf of the SMBus device 00:1f.4 for this variant.
