+From: Matrix Screen Controller maintainers
+Subject: [PATCH] arm64: dts: walnutpi: describe AXP313A on eMMC variant
+
+The vendor eMMC board DTS duplicates the PMIC description instead of
+including the non-eMMC board DTS.  Apply the same AXP313A regulator mapping
+to both variants so either boot-device layout gets the cpufreq and rail
+safety fix.
