From d7cf67fc940264e2ad6e60eaa914a214df9b81d8 Mon Sep 17 00:00:00 2001 From: Peter Seiderer Date: Tue, 21 Sep 2021 22:21:34 +0200 Subject: [PATCH] board/raspberrypicm4io-64: enable RTC and USB overlays The CM4 IO Board is equipped with an on-board RTC connected over I2C, and has USB 2.0 host ports. This commit loads the appropriate overlays to enable both. The USB 2.0 interface is by default disabled on CM4 to reduce the power consumption so it needs to be explicitly enabled on the CM4 IO Board to use the USB ports.
