usb: dwc2: add support for STM32MP15 SoCs USB OTG HS and FS

2020-03-15T09:06:39Z

This patch introduces a new parameter to activate external ID pin and valid vbus level detection, required on STM32MP15 SoC to support dual role, either in HS or FS. The STM32MP15 SoC uses the GGPIO register to enable the level detection. The level detector requires to be powered. Also adds the params structures for STM32MP15 OTG HS and STM32MP1 OTG FS.

USB: dwc2: Don't turn off the usbphy in suspend if wakeup is enabled

2019-06-18T08:58:28Z

If the 'snps,need-phy-for-wake' is set in the device tree then: - We know that we can wakeup, so call device_set_wakeup_capable(). The USB core will use this knowledge to enable wakeup by default. - We know that we should keep the PHY on during suspend if something on our root hub needs remote wakeup. This requires the patch (USB: Export usb_wakeup_enabled_descendants()). Note that we don't keep the PHY on at suspend time if it's not needed because it would be a power draw. If we later find some users of dwc2 that can support wakeup without keeping the PHY on we may want to add a way to call device_set_wakeup_capable() without keeping the PHY on at suspend time.

usb: dwc2: Delayed status support

2019-05-03T06:13:48Z

Added delayed status support for Control transfers. Tested in all 3 modes: Slave, BDMA and DDMA. Performed tests: USB CV (Ch9 and MSC), Control Read/Write tests using Synopsys USB test environment function driver. Signed-off-by: Minas Harutyunyan Signed-off-by: Felipe Balbi

usb: dwc2: Move phy init into core

2019-05-03T06:13:48Z

As the phy initialization is almost the same in host and gadget mode. This only move the phy initialization functions into core.c for now, the goal is to share theses functions between the two modes. Acked-by: Minas Harutyunyan Signed-off-by: Jules Maselbas Signed-off-by: Felipe Balbi

usb: dwc2: gadget: Replace phyif with phy_utmi_width

2019-05-03T06:13:48Z

The phy utmi width information is already set in hsotg params, phyif is only used in few places and I don't see any reason to not use hsotg's params. Moreover the utmi width was being forced to 16 bits by platform initialization which doesn't take in account HW configuration.

usb: dwc2: optionally assert phy reset when waking up

2019-05-03T06:13:47Z

On the rk3288 USB host-only port (the one that's not the OTG-enabled port) the PHY can get into a bad state when a wakeup is asserted (not just a wakeup from full system suspend but also a wakeup from autosuspend). We can get the PHY out of its bad state by asserting its "port reset", but unfortunately that seems to assert a reset onto the USB bus so it could confuse things if we don't actually deenumerate / reenumerate the device. We can also get the PHY out of its bad state by fully resetting it using the reset from the CRU (clock reset unit), which does a more full reset. The CRU-based reset appears to actually cause devices on the bus to be removed and reinserted, which fixes the problem (albeit in a hacky way). It's unfortunate that we need to do a full re-enumeration of devices at wakeup time, but this is better than alternative of letting the bus get wedged.
