Currently the driver don't support pm_ops. These ops are not necessary if the supply isn't switchable (always on). This assumptions seems to be wrong because no one needs a powered hub during suspend-to-ram/disk. So adding simple_dev_pm_ops to be able to switch off the hub during suspend and to restore the config after a resume operation. Signed-off-by:

Currently the reset handler was always called to deassert the reset line because assert the line was done during probe. Now if we want to support pm by turn of the supply we need to call this routine twice and the i2c_lock_bus is done twice too. To simplify that we can drop the state and just do a reset in one go. So a future pm operation don't need to lock the i2c bus twice. Signed-off-by:

Currently we don't handle the supply. We need to add the supply support to be able to switch the supply off e.g. during a suspend-to-ram operation. So we can guarantee a correct (re-)initialization. Signed-off-by:

When R-Car Gen3 USB 2.0 is in Gadget mode, if host is detached an interrupt will be generated and Suspended state bit is set in interrupt status register. Interrupt handler will call driver->suspend(composite_suspend) if suspended state bit is set. composite_suspend will call ffs_func_suspend which will post FUNCTIONFS_SUSPEND and will be consumed by user space application via /dev/ep0. To be able to detect host detach, extend the DVSQ_MASK to cover the Suspended bit of the DVSQ[2:0] bitfield from the Interrupt Status Register 0 (INTSTS0) register and perform appropriate action in the DVST interrupt handler (usbhsg_irq_dev_state). Without this commit, disconnection of the phone from R-Car-H3 ES2.0 Salvator-X CN9 port is not recognized and reverse role switch does not happen. If phone is connected again it does not enumerate. With this commit, disconnection will be recognized and reverse role switch will happen by a user space application. If phone is connected again it will enumerate properly and will become visible in the output of 'lsusb'. Signed-off-by:

Commit [1] enabled the possibility of checking the DVST (Device State Transition) bit of INTSTS0 (Interrupt Status Register 0) and calling the irq_dev_state() handler if the DVST bit is set. But neither commit [1] nor commit [2] actually enabled the DVSE (Device State Transition Interrupt Enable) bit in the INTENB0 (Interrupt Enable Register 0). As a consequence, irq_dev_state() handler is getting called as a side effect of other (non-DVSE) interrupts being fired, which definitely can't be relied upon, if DVST notifications are of any value. Why this doesn't hurt is because usbhsg_irq_dev_state() currently doesn't do much except of a dev_dbg(). Once more work is added to the handler (e.g. detecting device "Suspended" state and notifying other USB gadget components about it), enabling DVSE becomes a hard requirement. Do it in a standalone commit for better visibility and clear explanation.

Similar to usbhs_status_get_ctrl_stage(), *_get_device_state() is not supposed to return any error code since its return value is the DVSQ bitfield of the INTSTS0 register. According to SoC HW manual rev1.00, every single value of DVSQ[2:0] is valid and none is an error: ----8<---- Device State 000: Powered state 001: Default state 010: Address state 011: Configuration state 1xx: Suspended state ----8<---- Hence, simplify the function body. The motivation behind dropping the switch/case construct is being able to implement reading the suspended state. The latter (based on the above DVSQ[2:0] description) doesn't have a unique value, but is rather a list of states (which makes switch/case less suitable for reading/validating it): 100: (Suspended) Powered state 101: (Suspended) Default state 110: (Suspended) Address state 111: (Suspended) Configuration state Signed-off-by:

There is a clock enable counter run away problem in resume ohci_at91. Code enables clock that was never disabled in case of non wakeup interface. That would make clock unstoppable in future. Use proper alternative to start clocks only if they were stopped before. Signed-off-by:

In order to completely remove marginal power consumption in PM suspend, we need to let the controller settle down before being stopped. In ohci_hcd_at91_drv_suspend() function, one additional delay is needed before to stop the clocks. Reported-by:

When removing the ohci-at91 module, the fact of not running complete shutdown of all the ports was keeping additional analog cells consuming power for no reason. Doing Reset (OHCI_HCR) to HcCommandStatus register is the way to go, but using the OHCI controller shutdown procedure is just perfect for this. Signed-off-by:
