Subject: [PATCH v2 0/7] arm64: dts: qcom: sa8775p: add more IOMMUs

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

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

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 (6):
  dt-bindings: clock: qcom: describe the GPUCC clock for SA8775P
  arm64: defconfig: enable the SA8775P GPUCC driver
  dt-bindings: iommu: arm,smmu: enable clocks for sa8775p
  arm64: dts: qcom: sa8775p: add the pcie smmu node
  arm64: dts: qcom: sa8775p: add the GPU clock controller node
  arm64: dts: qcom: sa8775p: add the GPU IOMMU node
