Subject: [PATCH 012/153] drv:phy: sun4i-usb: Allow reset line to be shared
|
||
|
|
|
||
|
|
The USB HCIs (and PHYs?) in Allwinner's newer generation SoCs (H616)
|
||
|
|
rely on the reset line of USB PHY 2 to be de-asserted, even when only
|
||
|
|
one of the other PHYs is actually in use.
|
||
|
|
|
||
|
|
To make those ports work, we include this reset line in the HCIs' resets
|
||
|
|
property, which requires this line to be shareable.
|
||
|
|
|
||
|
|
Change the call to allocate the reset line to mark it as shared, to
|
||
|
|
enable the other ports on those SoCs.
|
||
