Subject: [PATCH v4 0/6] Add support for PCIe3 on x1e80100

This series add support for PCIe3 on x1e80100.

PCIe3 needs additional set of clocks, regulators and new set of PCIe QMP
PHY configuration compare other PCIe instances on x1e80100. Hence add
required resource configuration and usage for PCIe3.

v3->v4:
1. Reword commit msg of [PATCH v3 5/6]
2. Drop opp-table property from qcom,pcie-sm8450.yaml
3. Add Reviewed-by tag

v2->v3:
1. Use 'Gen 4 x8' in commit msg
2. Move opp-table property to qcom,pcie-common.yaml
3. Add Reviewed-by tag
4. Add global interrupt and use GIC_SPI for the parent interrupt specifier
5. Use 0x0 in reg property and use pcie@ for pcie3 device node
6. Show different IP version v6.30 in commit msg
7. Add logic in controller driver to have new ops for x1e80100

v2->v1:
1. Squash [PATCH 1/8], [PATCH 2/8],[PATCH 3/8] into one patch and make the
   indentation consistent.
2. Put dts patch at the end of the patchset.
3. Put dt-binding patch at the first of the patchset.
4. Add a new patch where opp-table is added in dt-binding to avoid dtbs
   checking error.
5. Remove GCC_PCIE_3_AUX_CLK, RPMH_CXO_CLK, put in TCSR_PCIE_8L_CLKREF_EN
   as ref.
6. Remove lane_broadcasting.
7. Add 64 bit bar, Remove GCC_PCIE_3_PIPE_CLK_SRC, 
   GCC_CFG_NOC_PCIE_ANOC_SOUTH_AHB_CLK is changed to
   GCC_CFG_NOC_PCIE_ANOC_NORTH_AHB_CLK.
8. Add Reviewed-by tag.
9. Remove [PATCH 7/8], [PATCH 8/8].
