From bc5957567e76e1e8cf18a6692963eef43d66ac3e Mon Sep 17 00:00:00 2001 From: Robin Gong Date: Wed, 12 May 2021 21:16:57 +0800 Subject: [PATCH] MLK-25465-2: arm64: dts: imx8mn-ddr4-evk: update vdd_soc in suspend to 0.75v To match with the latest datasheet, besides, correct vdd_soc to buck1 instead of buck2. But this patch should be no any impact since uboot has already done the same thing. Anyway correct it, since rohm driver has this ability now and could be indepedent of uboot in the future.
