Subject: [PATCH 8/9] ARM: dts: Add Raspberry Pi Compute Module 4 IO Board
Date: Sun, 1 Aug 2021 14:28:51 +0200 [thread overview]
Message-ID: <1627820932-7247-9-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1627820932-7247-1-git-send-email-stefan.wahren@i2se.com>
This adds the matching carrier for Raspberry Pi Compute Module 4.
Instead of xHCI USB host controller there is just a USB 2.0 interface
connected to the DWC2 controller from the BCM2711. As a result
there is a free PCIe Gen 2 socket. Also there are 2 full-size HDMI 2.0
connectors.
