Subject: [PATCH] r8152: adjust the flow of power cut for RTL8153B
|
|
|
|
commit 80fd850b31f09263ad175b2f640d5c5c6f76ed41 upstream.
|
|
|
|
For runtime resuming, the RTL8153B may be resumed from the state
|
|
of power cut, when enabling the feature of UPS. Then, the PHY
|
|
would be reset, so it is necessary to be initailized again.
|
|
|
|
Besides, the USB_U1U2_TIMER also has to be set again, so I move
|
|
it from r8153b_init() to r8153b_hw_phy_cfg().
