From fde109dc75686cf3d49970ea838d76ec840f4347 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Mon, 3 Feb 2020 19:16:53 +0530 Subject: [PATCH] arm: dts: k3-j721e-r5-common-proc-board: Disable power-domains for mcu uart mcu uart will be used during uart boot for loading sysfw.itb. Since sysfw is not yet available during uart load, power-domain cannot be enabled. We need to rely on ROM for doing that, so disable power-domains and clocks for mcu uart. Also fix the mcu uart frequency.
