Subject: [PATCH 344/464] phy: phy-rockchip-inno-usb2: Decrease delay between
|
||
|
|
port init and charger detection
|
||
|
|
|
||
|
|
When used on systems with TCPM, the charger detection via USB2.0 PHY
|
||
|
|
will take too much time during boot, so the fusb302 driver will not
|
||
|
|
be able to get the result, and will set incorrect current_max on
|
||
|
|
its power supply device.
|
||
|
|
|
||
|
|
This will lead to failure to charge when the device is powered up
|
||
|
|
while connected to non-PD charger.
|
||
|
|
|
||
|
|
Decreasing delay of otg_sm_work from 6s to 500ms ensures that
|
||
|
|
port type detection via the PHY will finish well in time for
|
||
|
|
TCPM to be able to use its result when Rp=default is detected
|
||
|
|
via CC pins.
