Subject: arm64: dts: rockchip: fix second M.2 slot on ROCK 5T
|
|
|
|
The Radxa ROCK 5T has two M.2 slots, much like the Radxa Rock 5B+. As it
|
|
stands, the board won't be able to use PCIe3 if the second M.2 slot is
|
|
in use.
|
|
|
|
Fix this by adding the necessary node enablement and data-lanes property
|
|
to the ROCK 5T device tree, mirroring what's in the ROCK 5B+ device
|
|
tree.
|
