From 8a9f2c19d44c8db105d0031efd9a2a43d7d1797f Mon Sep 17 00:00:00 2001 From: Bryan Brattlof Date: Fri, 3 Oct 2025 07:15:45 -0500 Subject: [PATCH] arm: dts: k3-am654: add vin-supply regulators for DDR As of commit f98d812e5353 ("power: regulator: Add vin-supply for GPIO and Fixed regulators") we must ensure the parent nodes of a regulator are present in DT if they are described in the vin-supply property For the am65x reference board the DRAM chips are fed by the 3v3 rail which is fed by the main 12v rail. Add the bootph properties to these DT nodes to prevent them from being pruned during the SPL build so we can enable power to the DRAM chips Signed-off-by: Bryan Brattlof Tested-by: Nishanth Menon --- arch/arm/dts/k3-am654-base-board-u-boot.dtsi | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/arm/dts/k3-am654-base-board-u-boot.dtsi b/arch/arm/dts/k3-am654-base-board-u-boot.dtsi index 4fd188fa191..baf5dd562f9 100644 --- a/arch/arm/dts/k3-am654-base-board-u-boot.dtsi +++ b/arch/arm/dts/k3-am654-base-board-u-boot.dtsi @@ -17,6 +17,14 @@ bootph-all; }; +&evm_12v0 { + bootph-all; +}; + +&vcc3v3_io { + bootph-all; +}; + &vtt_supply { bootph-all; }; -- 2.47.3
