Subject: [PATCH 189/224] dt-bindings: usb: mtu3: update USB wakeup properties
|
||
|
|
|
||
|
|
Add two arguments in "mediatek,syscon-wakeup" to support multi
|
||
|
|
wakeup glue layer between SSUSB and SPM, and use standard property
|
||
|
|
"wakeup-source" to replace the private "mediatek,enable-wakeup"
|
