From: Honghui Zhang The clocks was not enabled when enable MSI. This patch fix this issue by calling mtk_pcie_enable_msi in mtk_pcie_startup_port_v2 since the clock was all enabled at that time. The function of mtk_pcie_startup_port_v2's define location is re-arranged to avoid

[PATCH v2 1/4] PCI: mediatek: fixup mtk_pcie_find_port logical

From: Honghui Zhang The Mediatek's host controller has two slots, each with it's own control registers. The host driver need to identify which slot was connected in order to access the device's configuration space. There's problem for current host driver to find out which slot was connected to

[PATCH v2 4/4] PCI: mediatek: Add loadable kernel module support

From: Honghui Zhang Implement remove callback function for Mediatek PCIe driver to add loadable kernel module support. Signed-off-by: Honghui Zhang --- drivers/pci/controller/Kconfig | 2 +- drivers/pci/controller/pcie-mediatek.c | 60 +++--- 2 files

[PATCH v2 0/4] PCI: mediatek: fixup find_port, enable_msi and add pm, module support

From: Honghui Zhang This patchset includes misc patchs: The first patch fixup the mtk_pcie_find_port logical which will cause system could not touch the EP's configuration space which was connected to PCIe slot 1. The second patch fixup the enable msi logical, the operation to enable msi

[PATCH v2 3/4] PCI: mediatek: Add system pm support for MT2712 and MT7622

From: Honghui Zhang The MTCMOS of PCIe Host for MT2712 and MT7622 will be off when system suspend, and all the internal control register will be reset after system resume. The PCIe link should be re-established and the related control register values should be re-set after system resume.

[PATCH v4] PCI: mediatek: Add system pm support for MT2712

From: Honghui Zhang The MTCMOS of PCIe Host for MT2712 will be off when system suspend, and all the internal control register will be reset after system resume. The PCIe link should be re-established and the related control register values should be re-set after system resume. Signed-off-by:

[PATCH v7 0/2] PCI: mediatek: Fixups for the IRQ handle routine and MT7622's class code

From: Honghui Zhang Two fixups for mediatek's host bridge: The first patch fixup class type and vendor ID for MT7622. The second patch fixup the IRQ handle routine by using irq_chip solution to avoid IRQ reentry which may exist for both MT2712 and MT7622. Change
