[PATCH v3 1/4] dt-bindings: usb: mtk-xhci: add support mt8196

[Chunfeng Yun]

There are three USB controllers on mt8196, each controller's wakeup
control is different, add some specific versions for them, and add
a new compatilbe for mt8196.

Since all of the USB controllers of the MT8196 SoC are behind MTU3, and
since the wakeup control for all of them will be handled by the MTU3 driver
and *not* by the xhci-mtk driver....

NACK!

Please drop this commit.

Angelo

As I explained before, this is used for back compatible, and we always
use host only for some projects, and don not use mtu3 driver, that will
make dts complicated.

And xhci-mtk's patch is higher priority than mtu3's, I already add
mtu3's patch as you suggestion, but I still hope to keep it. provide
one more option is better for our customers.

Please help to pick up these patches, I also hate to add these specific
wakeup ways, but our haredware designer do not follow the hwip rules
sometimes.

[PATCH v3 4/4] usb: mtu3: add support remote wakeup of mt8196

[Chunfeng Yun]

There are three USB controllers on mt8196, each controller's wakeup
control is different, add some specific versions for them.

v3: add the ommitted third dual-role controller suggested by Angelo
v2: add wakeup for dual-role controllers
