Merge branch 'pci/pwrctrl-tc9563'
- Add a struct pci_ops.assert_perst() function pointer to assert/deassert
PCIe PERST# and implement it for the qcom driver (Krishna Chaitanya
Chundru)
- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe switch,
which must be held in reset after poweron so the pwrctrl driver can
configure the switch via I2C before bringing up the links (Krishna
Chaitanya Chundru)
* pci/pwrctrl-tc9563:
PCI: pwrctrl: Add power control driver for TC9563
PCI: qcom: Implement .assert_perst()
PCI: dwc: Implement .assert_perst() for dwc glue drivers
PCI: Add .assert_perst() to control PCIe PERST#
dt-bindings: PCI: Add binding for Toshiba TC9563 PCIe switch
