From 0417ef17ac1d164f09d12cab0b8e3da03ffb5da3 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 9 Dec 2019 10:43:03 -0300 Subject: mx7ulp: Add support for Embedded Artists COM board The Embedded Artists COM board is based on NXP i.MX7ULP. It has a BD70528 PMIC from Rohm with discrete DCDC powering option and improved current observability (compared to the existing NXP i.MX7ULP EVK). Add the initial support for the board.
