2022-07-27usb: typec: ucsi: stm32g0: add bootloader supportFabrice Gasnier1-13/+526
STM32G0 comes with STM32 bootloader in its system memory. Add support for some I2C bootloader commands as described in application notes AN2606 and AN4221, to enable STM32G0 UCSI firmware update. Upon probing, the driver needs to know the STM32G0 state: - In bootloader mode, STM32 G0 answers at i2c addr 0x51. - In running mode, STM32 G0 firmware may answer at two address. - The main address specified in DT is used for UCSI. - 0x51 addr can be re-used for FW controls like getting software version or jump to booloader request. So probe using the main firmware i2c address first, before attempting bootloader address (e.g. check for blank, erased or previously aborted firmware update).

2022-07-27usb: typec: ucsi: stm32g0: add support for stm32g0 controllerFabrice Gasnier3-0/+275
STM32G0 provides an integrated USB Type-C and power delivery interface. It can be programmed with a firmware to handle UCSI protocol over I2C interface. A GPIO is used as an interrupt line. Type-C connector can be used as a wakeup source (typically to detect changes on the port, like attach or detach). PM suspend / resume routines are used to enable wake irqs, and signal a wakeup event in case the IRQ has fired while in suspend. The i2c core is doing the necessary initialization when the "wakeup-source" flag is provided. Note: the interrupt handler shouldn't be called before the i2c bus resumes. So, the interrupts are disabled during suspend period, and re-enabled upon resume, to avoid i2c transfer while suspended, from the irq handler.

2022-07-27usb: typec: retimer: Add missing id check in match callbackNícolas F. R. A. Prado1-2/+7
The fwnode_connection_find_match() function handles two cases: named references and graph endpoints. In the second case, the match function passed in is called with the id to check for the match. However, the match function for the recently added type-c retimer class assumes the connection has already been matched (which is only true for the first case). The result is that with that change, all type-c nodes with graph endpoints defer probe indefinitely, independently of having a retimer connection or not. Add the missing check, like is done by the type-c mux and usb role switch code, to fix the issue.

2022-07-27USB: HCD: Fix URB giveback issue in tasklet functionWeitao Wang1-11/+15
Usb core introduce the mechanism of giveback of URB in tasklet context to reduce hardware interrupt handling time. On some test situation(such as FIO with 4KB block size), when tasklet callback function called to giveback URB, interrupt handler add URB node to the bh->head list also. If check bh->head list again after finish all URB giveback of local_list, then it may introduce a "dynamic balance" between giveback URB and add URB to bh->head list. This tasklet callback function may not exit for a long time, which will cause other tasklet function calls to be delayed. Some real-time applications(such as KB and Mouse) will see noticeable lag. In order to prevent the tasklet function from occupying the cpu for a long time at a time, new URBS will not be added to the local_list even though the bh->head list is not empty. But also need to ensure the left URB giveback to be processed in time, so add a member high_prio for structure giveback_urb_bh to prioritize tasklet and schelule this tasklet again if bh->head list is not empty. At the same time, we are able to prioritize tasklet through structure member high_prio. So, replace the local high_prio_bh variable with this structure member in usb_hcd_giveback_urb.

It returns error pointers if there is an allocation failure, or a similar issue. It returns NULL if no GPIO was assigned to the requested function. Print an error in either case.

Type C ports can be linked to retimers using firmware node device references (again, in a manner similar to "mode-switch").

2022-07-14usb: dwc3: core: Do not perform GCTL_CORE_SOFTRESET during bootupRohith Kollalsi1-3/+7
According to the programming guide, it is recommended to perform a GCTL_CORE_SOFTRESET only when switching the mode from device to host or host to device. However, it is found that during bootup when __dwc3_set_mode() is called for the first time, GCTL_CORESOFTRESET is done with suspendable bit(BIT 17) of DWC3_GUSB3PIPECTL set. This some times leads to issues like controller going into bad state and controller registers reading value zero. Until GCTL_CORESOFTRESET is done and run/stop bit is set core initialization is not complete. Setting suspendable bit of DWC3_GUSB3PIPECTL and then performing GCTL_CORESOFTRESET is therefore not recommended. Avoid this by only performing the reset if current_dr_role is set, that is, when doing subsequent role switching.
