From 614d47cc9303893c706c0c94516249eb3adaeb80 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Sun, 26 Sep 2021 14:05:17 +0200 Subject: [PATCH] arm64: dts: ti: iot2050: Add support for product generation 2 boards This adds the devices trees for IOT2050 Product Generation 2 (PG2) boards. We have Basic and an Advanced variants again, differing in number of cores, RAM size, availability of eMMC and further details. The major difference to PG1 is the used silicon revision (SR2.x on PG2).
