This series enables LPAC on a7xx GPUs
Currently hangcheck and recovery are broken as the patches to make them
work depend on https://lore.kernel.org/linux-arm-msm/20250911-preemption...
The series also depends on https://lore.kernel.org/linux-arm-msm/177919116291.814652...
to work correctly.

Anna Maniscalco (13):
iommu: arm-smmu-qcom: Configure lpac device with split address space
drm/msm: add support for lpac_domain in msm_mmu
drm/msm: look for lpac from dts
arm64: dts: qcom: sm8650: move smmu sid 1 to new lpac device
firmware: qcom: scm: Configure LPAC aperture
DEBUGGING: print contextbank and other ttbrs on fault
iommu: arm-smmu-qcom: Fixed mapping between sid and cb for gpu and lpac
HACK: use cb1 address in lpac dtb node
temp: add LPAC regs
drm/msm: initialize LPAC ring
drm/msm: Add LPAC submitqueue
drm/msm: set ctxbank and asid based on ring
drm/msm: add lpac ring to devcoredump
