Subject: [PATCH] arm64: dts: rockchip: Enable device-tree overlay support for select devices
Date: Thu, 28 Mar 2024 13:05:51 -0500 [thread overview]
Message-ID: <20240328180551.361381-1-macroalpha82@gmail.com> (raw)
From: Chris Morgan <macromorgan@hotmail.com>
Add the '-@' DTC option for the Rock 5B and Indiedroid Nova devices.
These two devices are relatively new both with external GPIO headers
for expansion. This does impact the filesize of the DTB substantially.
rk3588-rock-5b.dtb 75352 -> 150094 bytes
rk3588s-indiedroid-nova.dtb 69507 -> 136739 bytes
