[PATCH 2/3] arm: dts: omap: Add support for BeagleBone Black RevD
From: Robert Nelson
Date: Tue Sep 01 2026 - 17:43:26 EST
The BeagleBoard.org BeagleBone Black RevD and Industrial (00D0/EID0) are
redesigns of the BeagleBone Black Rev C3. They feature an IT66122 HDMI PHY to
replace the EOL NXP TDA19988. Additionally, these models include a larger eMMC
capacity to address the limited availability of 4GB modules.
