When the controller is configured to be dual role and it's in host mode,
if bind udc and gadgt driver, those gadget operations will do gadget
disconnect and finally pull down DP line, which will break host function.

For each platform devices which is created by device tree, the default
DMA mask is set by of_dma_configure when the device are created. So
delete the redundant code at driver.

B-device detects that bus is idle for more than TB_AIDL_BDIS min and
begins HNP by turning off pullup on DP, this allows the bus to discharge
to the SE0 state. This timer was missed and failed with PET test:
6.8.5 B-UUT HNP of USB OTG and EH automated compliance plan v1.2,
this patch is to fix this timing issue.

This reverts commit e765bfb73ff7.
In the most of cases, we only use one transaction per frame and the
frame rate may be high, If the platforms want to support multiple
transactions but less frame rate cases like [1] and [2], it can set
"non-zero-ttctrl-ttha" at dts.

In chipidea IP RTL, there is a very limited design for siTD, the detail
like below:
There is no Max Packet Size at siTD, so it uses one constant for both
Max Packet Size for packet and the packet size for the last transaction
when considering schedule.
If the ttctrl.ttha does not match against Hub Address field in siTD,
this constant is 188 bytes, else this constant is 1023 bytes.
If the ttctrl.ttha is non-zero value, RTL will use 188 as this constant,
so it will lose the data if the packet size is larger than 188 bytes, eg,
if we playback a wav which format is 48khz, 16 bits, 2 channels, the
packet size will be 192bytes, but the controller will only send 188 bytes
for this packet, the noise will be heared using USB audio card.
The use case is single transaction, but higher frame rate.
If the ttctr.ttha is zero value, we can send 1023 bytes within one
transaction, but the controller will not accept the coming tranaction
if it considers the schedule time is less than 1023 bytes. So the
limitation is we can't schedule as many as transactions within frame.
If the total bytes is already 256 bytes for previous transactions within
frame, it can't accept another transaction. The use case is multiple
transactions, but less frame rate.

Until now the imx23 uses the imx27 platform flag. But the
imx23 needs the flag CI_HDRC_TURN_VBUS_EARLY_ON, too. So
fix this by adding a separate platform flag.

If we use USB ID pin as wakeup source, and there is a USB block
device on this USB OTG (ID) cable, the system will be deadlock
after system resume.
The root cause for this problem is: the workqueue ci_otg may try
to remove hcd before the driver resume has finished, and hcd will
disconnect the device on it, then, it will call device_release_driver,
and holds the device lock "dev->mutex", but it is never unlocked since
it waits workqueue writeback to run to flush the block information, but
the workqueue writeback is freezable, it is not thawed before driver
resume has finished.
When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it
tries to get its device lock "dev->mutex", but it can't get it forever,
then the deadlock occurs. Below call stacks show the situation.
So, in order to fix this problem, we need to change workqueue ci_otg
as freezable, then the work item in this workqueue will be run after
driver's resume, this workqueue will not be blocked forever like above
case since the workqueue writeback has been thawed too.
Tested at: i.mx6qdl-sabresd and i.mx6sx-sdb.

call to of_find_property() before of_property_read_u32() is unnecessary.
of_property_read_u32() anyway calls to of_find_property() only.

Since we need to mount debugfs to show/store the things we
want to debug, it is duplicated to add another configuration
to enable it. Meanwhile, with CONFIG_USB_CHIPIDEA_DEBUG,
we can't support chipidea debugfs at runtime.

This allows to write
drm-$(CONFIG_AGP) += drm_agpsupport.o
without having to handle CONFIG_AGP=y vs. CONFIG_AGP=m. Only support
this syntax for modules, since built-in code depending on something
modular cannot work and init/Makefile actually relies on the current
semantics. There are a few drivers which adapted to the current
semantics out of necessity; these are fixed to also work when the
respective subsystem is modular.

Since the ci->role will be set after the host role start is complete, there
will be nobody cared irq during start host if usb irq enabled. This error
can be reproduced on i.mx6 sololite EVK board by:
1. disable otg id irq(IDIE) and disable all real otg properties of usbotg1
in dts.
2. boot up the board with ID cable and usb device connected.
3. echo gadget > /sys/kernel/debug/ci_hdrc.0/role
4. echo host > /sys/kernel/debug/ci_hdrc.0/role
5. irq 212: nobody cared.

Some HW design may use ID pin state to control vbus for otg port,
so before host role start, the vbus is already turned on, in this
case, we do not need wait vbus dropping below BSV.

Due to having hardware tx buffers less than 512 bytes in size, streaming
must be enabled on the Zynq for the udc to work at all. Add platform data
specific to the Zynq udc, which does not set the CI_HDRC_DISABLE_STREAMING
flag.

According to spec, there are functional and protocol stalls.
For functional stall, it is for bulk and interrupt endpoints,
below are cases for it:
- Host sends SET_FEATURE request for Set-Halt, the udc driver
needs to set stall, and return true unconditionally.
- The gadget driver may call usb_ep_set_halt to stall certain
endpoints, if there is a transfer in pending, the udc driver
should not set stall, and return -EAGAIN accordingly.
These two kinds of stall need to be cleared by host using CLEAR_FEATURE
request (Clear-Halt).
For protocol stall, it is for control endpoint, this stall will
be set if the control request has failed. This stall will be
cleared by next setup request (hardware will do it).
It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt"
test failure, meanwhile, this change has been verified by
USB2 CV Compliance Test and MSC Tests.
