Subject: [PATCH] arm64: tegra: p3310: Explicitly enable GPU
Date: Sat, 26 Apr 2025 19:45:32 -0500	[thread overview]
Message-ID: <20250426-tx2-gpu-v1-1-fa1c78dcdbdc@gmail.com> (raw)

The gpu node originally was explicitly left disabled as it was expected
for the bootloader to enable it. However, this is only done in u-boot.
If u-boot is not in the boot chain, this will never be enabled. Other
Tegra186 devices already explicitly enable the gpu, so make p3310 match.
