Subject: [PATCH RESEND 2/3] arm64: dts: amlogic: Fix the register name of the 'DBI' region
Date: Sat, 01 Nov 2025 09:59:41 +0530 [thread overview]
Message-ID: <20251101-pci-meson-fix-v1-2-c50dcc56ed6a@oss.qualcomm.com> (raw)
In-Reply-To: <20251101-pci-meson-fix-v1-0-c50dcc56ed6a@oss.qualcomm.com>
DT incorrectly specifies the 'DBI' region as 'ELBI'. DBI is a must have
region for DWC controllers as it has the Root Port and controller specific
registers, while ELBI has optional registers.
Hence, fix the DT for both Meson platforms.

Fixes: 1f8607d59763 ("arm64: dts: meson-g12a: Add PCIe node")
