pcieport 0000:00:00.0: bridge configuration invalid ([bus 00-00]), reconfiguring

[gravity_one]

Hello NXP,

Using IMX6 to connect WIFI by PCIE, I want to save more power, so I removed the WIFI driver during sleep. After waking up, the PCIE is abnormal, and the WIFI driver cannot be installed. Please help analyze this problem?
Please check the following logs:
1. pcieport 0000:00:00.0: bridge configuration invalid ([bus 00-00]), reconfiguring
2. 01:00.0 Network controller: Broadcom Limited Device 4415 (rev ff) (prog-if ff)
!!! Unknown header type 7f
Kernel modules: bcmdhd
3. The hardware resets the WIFI module. After scanning, you can see the WIFI, but the driver still cannot be installed.
