According to the BCM2835 datasheet the used Synopsys IP isn't a LPM-capable core. So disable these features and suppress these confusing warnings: dwc2 3f980000.usb: dwc2_check_params: Invalid parameter lpm=1 dwc2 3f980000.usb: dwc2_check_params: Invalid parameter lpm_clock_gating=1 dwc2 3f980000.usb: dwc2_check_params: Invalid parameter besl=1 dwc2 3f980000.usb: dwc2_check_params: Invalid parameter hird_threshold_en=1 Signed-off-by: Stefan Wahren <stefan.wahren@xxxxxxxx> --- drivers/usb/dwc2/params.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/usb/dwc2/params.c b/drivers/usb/dwc2/params.c index 24ff5f2..a158abb 100644 --- a/drivers/usb/dwc2/params.c +++ b/drivers/usb/dwc2/params.c @@ -47,6 +47,10 @@ static void dwc2_set_bcm_params(struct dwc2_hsotg *hsotg) p->max_transfer_size = 65535; p->max_packet_count = 511; p->ahbcfg = 0x10; + p->lpm = false; + p->lpm_clock_gating = false; + p->besl = false; + p->hird_threshold_en = false; } static void dwc2_set_his_params(struct dwc2_hsotg *hsotg) -- 2.7.4
