Hello,
This change looks reasonable, I remember the similar issue was in
s3c-hsotg driver
and it caused kernel ops on driver probe, when bootloader left dwc2
enabled.
The other way of solving it would be to add
irq_set_status_flags(irq, IRQ_NOAUTOEN);
before devm_request_irq() and then call enable_irq(irq) after
dwc2_lowlevel_hw_enable().
Best regards
unfortunately this fixes only the oops. I need to revert commit
09a75e85779014 ("usb: dwc2: refactor common low-level hw code to
platform.c") to get USB working again.
In dwc2_lowlevel_hw_init the following statement on Raspberry Pi seems
to never come true:
if (!hsotg->phy && !hsotg->uphy && !hsotg->plat) {
dev_err(hsotg->dev, "no platform data or transceiver defined\n");
return -EPROBE_DEFER;
}
This looks wrong to me. According to dwc2 binding the PHY could be
optional, isn't it?
Best regards
Stefan
