This patch fixes an issue that sometimes this controller is not able
to complete the Control write status stage.
This driver should enable DCPCTR.CCPL and PID_BUF to complete the status
stage. However, if this driver detects the ctrl_stage interruption first
before the control write data is received, this driver will clear the
PID_BUF wrongly in the usbhsf_pio_try_pop(). To avoid this issue, this
patch doesn't clear the PID_BUF in the usbhsf_pio_try_pop().
(Since also the privious code doesn't disable the PID_BUF after a control
transfer was finished, this patch doesn't have any side efforts.)

After the renesas_usbhs driver is enabled in ARM multi_v7_defconfig,
we now get a new warning:
renesas_usbhs/mod.c: In function 'usbhs_interrupt':
renesas_usbhs/mod.c:246:7: warning: 'intenb1' may be used uninitialized in this function [-Wmaybe-uninitialized]
gcc correctly points to a problem here, for the case that the
device is in host mode, we use the intenb1 variable without
having assigned it first. The state->intsts1 has a similar
problem, but gcc cannot know that.
This avoids the problem by initializing both sides of the
comparison to zero when we don't read them from the respective
registers.

According to the gadget.h, a "complete" function will always be called
with interrupts disabled. However, sometimes usbhsg_queue_pop() function
is called with interrupts enabled. So, this function should be held by
usbhs_lock() to disable interruption. Also, this driver has to call
spin_unlock() to avoid spinlock recursion by this driver before calling
usb_gadget_giveback_request().
Otherwise, there is possible to cause a spinlock suspected in a gadget
complete function.

Some Renesas SoCs have the USB-DMAC. It is able to terminate transfers
when a short packet is received, even if less bytes than the transfer
counter size have been received. Also, it is able to send a short
packet even if the packet size is not multiples of 8bytes.
Since the previous code has used the interruption of USBHS controller
when receiving packets even if this driver has used a dmac, a lot of
interruptions has happened. This patch will reduce such interruptions.
This patch allows to use the USB-DMAC on R-Car H2 and M2.

The renesas usbhs driver calls extcon_get_edev_by_phandle(), which
is defined in drivers/extcon/extcon-class.c, and that can be a
loadable module. If the extcon-class support is disabled, usbhs
will work correctly for all devices that do not need extcon.
However, if extcon-class is a loadable module, and usbhs is
built-in, the kernel fails to link. In order to solve that,
we need a Kconfig dependency that allows extcon to be disabled
but does not allow usbhs built-in if extcon is a module.

USB connector corresponding to USB port 0 driven either by EHCI/OHCI or Renesas
USBHS gadget controller. And we'd like the host/gadget drivers to work based on
the cable type connected. An 'extcon' driver for MAX3355 has been written, so we
only need to bind to it via device tree which I'm doing in this patch.
(Perhaps, it would also make sense to use OTG HNP when the USBHS host mode is

According to the datasheet, this driver should clear the INTSTS0.CTRT
bit before this controller detects the next stage transition. Otherwise,
the driver may not be able to clear the bit after the controller went to
the next stage transition. After that, the driver will not be able to
clear the INTSTS0.VALID, and a usb control transfer will not finish
finally.
If we use the testusb tool, it is easy to reproduce this issue:
# testusb -a -t 10
Since the previous code handled a data stage and a status stage in
the usbhsf_pio_try_push(), it may not clear the INTSTS0.CTRT at the
right timing.
So, this patch change the timing of usbhs_dcp_control_transfer_done()

This commit is based on previous work by

out to have a high probability of regressing
many UDC drivers because of a blind search & replace

pointer when it should be NULL, thus causing UDCs

This patch fixes an issue that the renesas_usbhs driver in gadget mode
cannot work correctly even if I disabled DMAC of the driver when I used

When a usb cable is re-connected, the renesas_usbhs driver calls the

call the usbhsp_flags_init() when usbhsg_ep_disable() is called.
So, if a gadget driver calls usb_ep_enable() and usb_ep_disable() again
and again, the renesas_usbhs driver will output the following log:
