[PATCH RFC 0/4] Devicetree support for Glymur GPU

[PATCH RFC 0/4] Devicetree support for Glymur GPU

[Akhil P Oommen]

This series adds the necessary Device Tree bits to enable GPU support
on the Glymur-based CRD devices. The Adreno X2-85 GPU present in Glymur
chipsets is based on the new Adreno A8x family of GPUs. It features a new
slice architecture with 4 slices, significantly higher bandwidth
throughput compared to mobile counterparts, raytracing support, and the
highest GPU Fmax seen so far on an Adreno GPU (1850 Mhz), among other
improvements.

This series includes patches that add GPU SMMU, GPU/GMU support, and a
patch to enable the GPU/GMU nodes on the CRD. Keen-eyed readers may
notice that the secure firmware property is missing. This is
intentional: The Glymur-based laptop platforms generally allow booting
Linux at EL2 (yay!), which means the zap firmware not required here.

The series is marked as RFC because an update is required in the
gxclkctl/drm drivers to properly support the IFPC feature across all A8x
GPUs. We plan to post a separate series shortly to address this. I prefer
to merge the DT series after that series is acked, so that we retain the
flexibility adjust the DT bindings if needed.

This series is only compile tested on linux-next. But I have cherry-picked
and verified the functionality on a downstream tree which is pretty close
to upstream. Also, there is a dtb-check error for the adreno smmu node. I
will fix that in the next revision.

[PATCH RFC 3/4] arm64: dts: qcom: Add GPU support for Glymur

[Akhil P Oommen]

The Adreno X2 series GPU present in Glymur SoC belongs to the A8x
family. It is a new HW IP with architectural improvements as well
as different set of hw configs like GMEM, num SPs, Caches sizes etc.

Add the GPU and GMU nodes to describe this hardware.

Is this going to be a default mode for other laptops too? Otherwise it
might be better to keep ZAP node enabled by default and disable it here.

I believe so. Anyway the laptops are hitting the market right now. If
anyone reports that the EL2 is locked down, we can revisit this.
