Panthor is the open-source implementation for the Arm GPU Valhall series
both in the Linux kernel and Mesa userspace. In the latter, the panfrost
"driver" is actually handling this version of the Arm GPU. One therefore
needs to enable kmsro and panfrost in PACKAGECONFIG to be able to use
this open-source implementation.

The open-source implementation still requires a proprietary blob which
is running on the GPU: mali_csffw.bin. Note that the closed-source
implementation (libmali and vendor kernel drivers) also require this
blob.

Right now, we're still missing a linux-yocto v6.10+ to be able to test
this with everything upstream in Yocto/OE, but I was able to
successfully test this with kmscube on a downstream kernel (6.6 +
backported patches for GPU and custom patches for DSI support) on an
RK3588 Tiger.
