Hi qiang,
In next series can you add logic in controller driver
to have new ops for this x1e80100 since this hardware
has smmuv3 support but currently the ops_1_9_0 ops which
is being used has configuring bdf to sid table which will
be not present for this devices.
Sure, bdf2sid map is not supported and required since we use smmuv3 for
pcie on x1e80100. Can I add a new ops which is same as ops_1_9_0 basically
and only config_sid callback is removed. Or add a new flag to determine if
we need to config bdf2sid map like no_l0s.
Hi Mani, what do you think about this?
Thanks,
Qiang

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.
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].
