kernel config
My hardware is a Pine64 Pinebook, which has an Analogix ANX6345 eDP bridge.
Starting with the 5.11 series, the screen fails to turn on after suspend,
producing the error: '[drm:anx6345_bridge_enable] *ERROR* Failed eDP
transmitter initialization: -13'.
Steps to reproduce:
1) boot series 5.11 kernel on the Pinebook
2) close lid
3) open lid.
Actual results: the display does not turn on.
Expected results: the display turns on.
Build date & hardware: 2021-03-07 on Arch Linux (x86-64 cross compile), run on
a Pine64 Pinebook.
Additional information: the latest 5.10 kernel (5.10.21) compiled with the same
config does not exhibit the bug.
