Added three patches to fix the mmc issue as described here: https://github.com/SolidHal/Librean/issues/17 Source for the patches is the chrome os kernel. Links to the commits can be found in the issue. Locking into version 4.17.2 for the time being. Better organized patches. Added logic to only apply tested patches on fresh kernel. Moved some debian build improvements in from my devsus master branch, including switching from xfce to lxqt. May be able to add option between the two in the future, as the issue that led to switching DEs may have been with the xorg video drivers that are now skipped by the script and not xfce itself. Cleaned up uneeded old configs

Subject: [PATCH] usb: dwc2: disable power_down on rockchip devices
|
|
|
|
The bug would let the usb controller enter partial power down,
|
|
which was formally known as hibernate, upon boot if nothing was plugged
|
|
in to the port. Partial power down couldn't be exited properly, so any
|
|
usb devices plugged in after boot would not be usable.
|
|
|
|
Before the name change, params.hibernation was false by default, so
|
|
_dwc2_hcd_suspend() would skip entering hibernation. With the
|
|
rename, _dwc2_hcd_suspend() was changed to use params.power_down
|
|
to decide whether or not to enter partial power down.
|
|
|
|
Since params.power_down is non-zero by default, it needs to be set
|
|
to 0 for rockchip devices to restore functionality.
|
|
|
|
This bug was reported in the linux-usb thread:
