Add the GPU and PCIe IOMMUs for sa8775p platforms as well as the required
GPU clock controller driver.

NOTE: I didn't pick up Krzysztof's tag for patch 4/5 as the patch changed
significantly.

v3 -> v4:
- fix the adreno smmu compatibles
- drop patches that are already in next

v2 -> v3:
- select QCOM_GDSC in Kconfig for the GPUCC module
- the GPU SMMU is actually an adreno SMMU so describe it as such and
  fix the DT
- fix the mapped memory size for the PCIe SMMU

v1 -> v2:
- remove unused include in the GPUCC driver
- remove unused clock from the GPUCC driver and make it compatible
  with the generic QCom GPUCC bindings
- put the new defconfig option in the right place (as per savedefconfig)
  and make the GPUCC driver a module rather than built-in
- describe the smmu clocks for sa8775p in dt-bindings

Bartosz Golaszewski (5):
  arm64: defconfig: enable the SA8775P GPUCC driver
  arm64: dts: qcom: sa8775p: add the pcie smmu node
  arm64: dts: qcom: sa8775p: add the GPU clock controller node
  dt-bindings: iommu: arm,smmu: enable clocks for sa8775p Adreno SMMU
  arm64: dts: qcom: sa8775p: add the GPU IOMMU node
