When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but not REGMAP_MMIO, so the kernel fails to link with an undefined reference to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in drivers/base/regmap/Kconfig. This creates the following dependency loop: drivers/of/Kconfig:68: symbol OF_IRQ depends on IRQ_DOMAIN kernel/irq/Kconfig:63: symbol IRQ_DOMAIN is selected by REGMAP drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_MMIO drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by SUNXI_SRAM drivers/soc/sunxi/Kconfig:4: symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI drivers/usb/musb/Kconfig:63: symbol USB_MUSB_SUNXI depends on GENERIC_PHY drivers/phy/Kconfig:7: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3 drivers/phy/broadcom/Kconfig:29: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS drivers/net/phy/Kconfig:12: symbol MDIO_BUS default is visible depending on PHYLIB drivers/net/phy/Kconfig:181: symbol PHYLIB is selected by ARC_EMAC_CORE drivers/net/ethernet/arc/Kconfig:18: symbol ARC_EMAC_CORE is selected by ARC_EMAC drivers/net/ethernet/arc/Kconfig:24: symbol ARC_EMAC depends on OF_IRQ To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY instead of depending on it.

I noticed that musb is blocking core retention for omap4 unlike for omap3. This is because for omap3 we have phy-twl4030-usb implement it's own PM runtime to handle errata "VUSB3V1 VBUS overvoltage debouncer not working when the PHY is powered down". That is done in order to keep the USB PHY powered when phy-twl4030-usb is loaded. For the other USB PHYs, we need to enable and disable the PHY based on musb PM runtime. With the session bit based PM runtime for musb core, we can now idle the USB PHY always when musb is idle. Note that adding these calls will not affect the twl4030 driver as it's phy functions will just query the PHY state without powering the PHY on or off. Signed-off-by:

Johan Hovold authored
Fix two long-standing bugs which could potentially lead to memory corruption or leave the port throttled until it is reopened (on weakly ordered systems), respectively, when read-URB completion races with unthrottle(). First, the URB must not be marked as free before processing is complete to prevent it from being submitted by unthrottle() on another CPU. CPU 1 CPU 2 ================ ================ complete() unthrottle() process_urb(); smp_mb__before_atomic(); set_bit(i, free); if (test_and_clear_bit(i, free)) submit_urb(); Second, the URB must be marked as free before checking the throttled flag to prevent unthrottle() on another CPU from failing to observe that the URB needs to be submitted if complete() sees that the throttled flag is set. CPU 1 CPU 2 ================ ================ complete() unthrottle() set_bit(i, free); throttled = 0; smp_mb__after_atomic(); smp_mb(); if (throttled) if (test_and_clear_bit(i, free)) return; submit_urb(); Note that test_and_clear_bit() only implies barriers when the test is successful. To handle the case where the URB is still in use an explicit barrier needs to be added to unthrottle() for the second race condition. Also note that the first race was fixed by 36e59e0d ("cdc-acm: fix race between callback and unthrottle") back in 2015, but the bug was reintroduced a year later.

Immediate data transfers (IDT) allow the HCD to copy small chunks of data (up to 8bytes) directly into its output transfer TRBs. This avoids the somewhat expensive DMA mappings that are performed by default on most URBs submissions. In the case an URB was suitable for IDT. The data is directly copied into the "Data Buffer Pointer" region of the TRB and the IDT flag is set. Instead of triggering memory accesses the HC will use the data directly. The implementation could cover all kind of output endpoints. Yet Isochronous endpoints are bypassed as I was unable to find one that matched IDT's constraints. As we try to bypass the default DMA mappings on URB buffers we'd need to find a Isochronous device with an urb->transfer_buffer_length <= 8 bytes. The implementation takes into account that the 8 byte buffers provided by the URB will never cross a 64KB boundary. Signed-off-by:

It's pointless to scan the hub' i2c-bus segment if GPIOs aren't supported by the system, since no GPIO-driven reset could be cleared by the driver then. Moreover if CONFIG_GPIOLIB is disabled the gpio_chip structure definition won't be available, which causes the incomplete type pointer dereference compilation error. In order to fix this we need to create an empty usb251x_check_gpio_chip() method returning zero, so the driver would skip the i2c-bus segment checking and proceed with further probing in this case.

Ajay Gupta authored
VirtualLink standard extends the DisplayPort Alt Mode by utilizing also the USB 2 pins on the USB Type-C connector. It uses the same messages as DisplayPort, but not the DP SVID. At the time of writing, USB IF has not assigned a Standard ID (SID) for VirtualLink, so the manufacturers of VirtualLink adapters use their Vendor IDs as the SVID. Since the SVID specific communication is exactly the same as with DisplayPort alternate mode, there is no need to implement separate driver for VirtualLink. We'll handle the current VirtualLink adapters with probe drivers, and once there is SVID assigned for it, we add it to the displayport alt mode driver. To support probing drivers, exporting the probe and remove functions, and also changing the DP_HEADER helper macro to use the SVID of the alternate mode device instead of the DisplayPort alt mode SVID.

This makes it possible to bind a driver to a DisplayPort alt mode adapter devices. The driver attempts to cope with the limitations of UCSI by "emulating" behaviour and attempting to guess things when ever possible in order to satisfy the requirements the standard DisplayPort alt mode driver has.

With UCSI the alternate modes, just like everything else related to USB Type-C connectors, are handled in firmware. The operating system can see the status and is allowed to request certain things, for example entering and exiting the modes, but the support for alternate modes is very limited in UCSI. The feature is also optional, which means that even when the platform supports alternate modes, the operating system may not be even made aware of them. UCSI does not support direct VDM reading or writing. Instead, alternate modes can be entered and exited using a single custom command which takes also an optional SVID specific configuration value as parameter. That means every supported alternate mode has to be handled separately in UCSI driver. This commit does not include support for any specific alternate mode. The discovered alternate modes are now registered, but binding a driver to an alternate mode will not be possible until support for that alternate mode is added to the UCSI driver. Tested-by:

CCGx has two copies of the firmware in addition to the bootloader. If the device is running FW1, FW2 can be updated with the new version. Dual firmware mode allows the CCG device to stay in a PD contract and support USB PD and Type-C functionality while a firmware update is in progress. First we read the currently flashed firmware version of both primary and secondary firmware and then compare it with version of firmware file to determine if flashing is required. Command framework is added to support sending commands to CCGx controller. We wait for response after sending the command and then read the response from RAB_RESPONSE register. Below commands are supported, - ENTER_FLASHING - RESET - PDPORT_ENABLE - JUMP_TO_BOOT - FLASH_ROW_RW - VALIDATE_FW Command specific mutex lock is also added to sync between driver and user threads. PD port number information is added which is required while sending PD_PORT_ENABLE command Signed-off-by:

SMBus slave configuration is activated by CFG_SEL[1:0]=0x1 pins state. This is the mode the hub is supposed to be to let this driver work correctly. But a race condition might happen right after reset is cleared due to CFG_SEL[0] pin being multiplexed with SMBus SCL function. In case if the reset pin is handled by a i2c GPIO expander, which is also placed at the same i2c-bus segment as the usb251x SMB-interface connected to, then the hub reset clearance might cause the CFG_SEL[0] being latched in unpredictable state. So sometimes the hub configuration mode might be 0x1 (as expected), but sometimes being 0x0, which doesn't imply to have the hub SMBus-slave interface activated and consequently causes this driver failure. In order to fix the problem we must make sure the GPIO-reset chip doesn't reside the same i2c-bus segment as the SMBus-interface of the hub. If it doesn't, we can safely block the segment for the time the reset is cleared to prevent anyone generating a traffic at the i2c-bus SCL lane connected to the CFG_SEL[0] pin. But if it does, nothing we can do, so just return an error. If we locked the i2c-bus segment and tried to communicate with the GPIO-expander, it would cause a deadlock. If we didn't lock the i2c-bus segment, it would randomly cause the CFG_SEL[0] bit flip. Signed-off-by:

Some tcpc device-drivers need to explicitly be told to watch for connection events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices being plugged into the Type-C port will not be noticed. For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to watch for connection events. But for single-role ports we've so far been falling back to just calling tcpm_set_cc(). For some tcpc-s such as the fusb302 this is not enough and no TCPM_CC_EVENT will be generated. Commit ea3b4d55 ("usb: typec: fusb302: Resolve fixed power role contract setup") fixed SRPs not working because of this by making the fusb302 driver start connection detection on every tcpm_set_cc() call. It turns out this breaks src->snk power-role swapping because during the swap we first set the Cc pins to Rp, calling set_cc, and then send a PS_RDY message. But the fusb302 cannot send PD messages while its toggling engine is active, so sending the PS_RDY message fails. Struct tcpc_dev now has a new start_srp_connection_detect callback and fusb302.c now implements this. This callback gets called when we the fusb302 needs to start connection detection, fixing fusb302 SRPs not seeing connected devices. This allows us to revert the changes to fusb302's set_cc implementation, making it once again purely setup the Cc-s and matching disconnect detection, fixing src->snk power-role swapping no longer working. Note that since the code was refactored in between, codewise this is not a straight forward revert. Functionality wise this is a straight revert and the original functionality is fully restored.

This commit renames start_drp_toggling to start_toggling and since the device-properties are parsed by the tcpm-core, adds a port_type parameter to the start_toggling callback so that the tcpc_dev driver knows the port-type and can act accordingly when it starts toggling. The new start_toggling callback now always gets called if defined, instead of only being called for DRP ports. To avoid this causing undesirable functional changes all existing start_drp_toggling implementations are not only renamed to start_toggling, but also get a port_type check added and return -EOPNOTSUPP when port_type is not DRP.
