Partial power down couldn't be exited properly, so any - usb devices plugged in after boot would not be usable. - - Before the name change, params.hibernation was false by default, so - _dwc2_hcd_suspend() would skip entering hibernation. With the - rename, _dwc2_hcd_suspend() was changed to use params.power_down - to decide whether or not to enter partial power down. - - Since params.power_down is non-zero by default, it needs to be set - to 0 for rockchip devices to restore functionality. - - This bug was reported in the linux-usb thread: - REGRESSION: usb: dwc2: USB device not seen after boot - - The commit that caused this regression is: - 6d23ee9caa6790aea047f9aca7f3c03cb8d96eb6 - -Signed-off-by: Hal Emmerich <hal@halemmerich.com> ---- - drivers/usb/dwc2/params.c | 1 + - 1 file changed, 1 insertion(+) - -diff --git a/drivers/usb/dwc2/params.c b/drivers/usb/dwc2/params.c -index bf7052e037d6..09292dc977e4 100644 ---- a/drivers/usb/dwc2/params.c -+++ b/drivers/usb/dwc2/params.c -@@ -81,6 +81,7 @@ static void dwc2_set_rk_params(struct dwc2_hsotg *hsotg) - p->host_perio_tx_fifo_size = 256; - p->ahbcfg = GAHBCFG_HBSTLEN_INCR16 << - GAHBCFG_HBSTLEN_SHIFT; -+ p->power_down = 0; - } - - static void dwc2_set_ltq_params(struct dwc2_hsotg *hsotg) --- -2.19.0 - |
