Subject: [PATCH 4/5] arm64: dts: qcom: Force host mode for USB on apq8016-sbc
|
||
|
|
|
||
|
|
Commit ed75d6a96905 ("arm64: dts: qcom: Collapse usb support into
|
||
|
|
one node") breaks host mode support on apq8016-sbc boards. This
|
||
|
|
is because the mux driver (tc7usb40mu) hasn't been merged.
|
||
|
|
Without that driver, we can't toggle the GPIO going to the mux to
|
||
|
|
route out the D+/D- lines to the USB hub that's on the board.
|
||
|
|
|
||
|
|
One solution would be to totally revert this change, but that
|
||
|
|
opens us up to other problems when two USB drivers are operating
|
||
|
|
the same hardware block at the same time. Let's modify the DT so
|
||
|
|
that the USB controller is always in host mode and connected to
|
||
|
|
the hub so that things like USB keyboards and mouses work. This
|
||
|
|
is the mode that most people prefer anyway with these devices. We
|
||
|
|
also delete the usb-switch node because the binding was never
|
||
|
|
accepted upstream.
|
||
|
|
|
||
|
|
In the future, we can add muxing support and then update the DT
|
||
|
|
to support both modes at runtime. Patches to support this are
|
||
|
|
already on the mailing list.
|
||
