Subject: arm64: dts: allwinner: h616: Add Mali GPU node
|
|
|
|
The Allwinner H616 SoC contains a Mali-G31 MP2 GPU, which is of the Mali
|
|
Bifrost family. There is a power domain specifically for that GPU, which
|
|
needs to be enabled to make use of the it.
|
|
|
|
Add the DT nodes for those two devices, and link them together through
|
|
the "power-domains" property.
|
|
Any board wishing to use the GPU would need to enable the GPU node and
|
|
specify the "mali-supply" regulator.
