Subject: [PATCH v9 0/4] PCI: mediatek: Spilt PCIe node to comply with hardware design
Date: Tue, 6 Apr 2021 11:44:06 +0800 [thread overview]
Message-ID: <20210406034410.24381-1-chuanjia.liu@mediatek.com> (raw)
There are two independent PCIe controllers in MT2712 and MT7622 platform. Each of them should contain an independent MSI domain.
In old dts architecture, MSI domain will be inherited from the root bridge, and all of the devices will share the same MSI domain.
Hence that, the PCIe devices will not work properly if the irq number which required is more than 32.
Split the PCIe node for MT2712 and MT7622 platform to comply with the hardware design and fix MSI issue.
change note:
v9:fix kernel-ci bot warning. In the scene of using new dts format,
when mtk_pcie_parse_port fails, of_node_put don't need to be called.
v8:remove slot node and fix yaml warning.
v7:dt-bindings file was modified as suggested by Rob, other file no
change.
v6:Fix yaml error. make sure driver compatible with old and
new DTS format.
v5:rebase for 5.9-rc1, no code change.
v4:change commit message due to bayes statistical bogofilter
considers this series patch SPAM.
v3:rebase for 5.8-rc1. Only collect ack of Ryder, No code change.
v2:change the allocation of MT2712 PCIe MMIO space due to the
allocation size is not right in v1.
