Subject: [PATCH 0854/1085] dts: rp1: nobble HS and FS/LS park mode for dwc3
|
||
|
|
xhci
|
||
|
|
|
||
|
|
Synopsys have recommended that we disable this feature entirely, as
|
||
|
|
Superspeed park mode can hang the controller, and Hs/FS/LS park mode can
|
||
|
|
cause performance degradation with bursty devices.
