Subject: [PATCH v2 0/2] PCI: mediatek-gen3: Support controlling power and
Date: Mon, 6 Mar 2023 14:40:57 +0800 [thread overview]
Message-ID: <20230306064059.7239-1-jian.yang@mediatek.com> (raw)
From: "jian.yang" <jian.yang@mediatek.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.
