Subject: [PATCH v2 0/2] PCI: mediatek-gen3: Support controlling power and

From: "jian.yang" <jian.yang@...iatek.com>

These series patches add support for controlling power supplies and reset
GPIO of a downstream component in Mediatek's PCIe GEN3 controller driver.

Changes in v2:
1. Remove an unnecessary property in dt-bindings file.
2. Use the flag 'GPIOD_OUT_LOW' to set initial state of a downstream
component's reset GPIO.
3. Keep downstream component powered on in suspend state if it need to
wakeup the system.

    reset
  PCI: mediatek-gen3: Add power and reset control feature for downstream
    component
