hi,
1:when the IMX6Q booting,it can not link up the PCI device-TW6869,the log is follow:
Bluetooth: Core ver 2.16
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: L2CAP socket layer initialized
Bluetooth: SCO socket layer initialized

2:when booting,IMX6Q can send PCIE_CLK and TX to TW6869,but the TW6869 can only output 240mV PCIE data to IMX6Q's PCIE_RX,then,IMX6Q stop the P[CIE_CLK and TX to TW6869,and logout fail.
the affix includes sch.

您好，
1：我们现在使用IMX6Q连接一个外部的PCIE芯片TW6869，IMX6Q在boot中提示不能LINK UPPCIE设备，如下：
imx6q-pcie 1ffc000.pcie: phy link never came up
imx6q-pcie 1ffc000.pcie: failed to initialize host
2：IMX6Q启动后，会有个瞬间，IMX6Q发送PCIE CLK和TX数据给TW6869，我们的板子TW6869会发个240mV的直流电平出来给IMX6Q的PCIE_RX（感觉正常的情况应该是TW6869发送有摆幅交流信号的PCIE数据给IMX6Q），之后BOOT提示不能LINK UP外设TW6869，之后IMX6Q就停止发送PCIE CLK和TX。
