Subject: [PATCH] bcm2838.dtsi: Use BCM2711 PCIe compatible string
|
|
|
|
The BCM2711 PCIe controller has a limited address range in the B0
|
|
silicon, and the driver uses a compatible string to identify the
|
|
limitation. The current Pi 4 firmware will override the compatible
|
|
string if it detects a downstream DTB and it is running on a newer
|
|
revision but set the default value to enable the workaround for
|
|
backwards-compatibility with old firmware.
