Follow the MSM8998 example and limit num_context_banks on SDM630 / SDM660 platforms. This allows Linux to make use of the A2NOC and KGSL SMMU, making it possible to enable GPU and WiFi on those platforms, and, in particular, Inforce IFC6560 SBC. Note, while WiFI starts up and can work for a short amount of time, MSS starts crashing with the following message: qcom-q6v5-mss 4080000.remoteproc: fatal error received: dog_hb.c:266:Task starvation: diag, ping: 4, triage with owner(d.dump 0xde5825 Note2: DTS changes should be applied only after IOMMU chages get merged. If it is not possible to get IOMMU changes into 6.12 in its last days of the merge window, I'd kindly ask for the immutable branch from the iommu subsys to be submerged into MSM tree.
