From 72ebb53bbaba7a59c890fdcc5ba55980ed9da1b7 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Thu, 17 Oct 2019 11:13:04 +0800 Subject: [PATCH] arm64: dts: imx8mn: Add LPDDR4 EVK board support i.MX8MN LPDDR4 EVK board shares most of the device as DDR4 EVK board, the ONLY difference are the DDR type and PMIC, add support for it and make it default i.MX8MN EVK board as usual. The PMIC driver is NOT ready, so cpu-freq needs to be disabled as it depends on regulator provided by PMIC.
