usb: gadget: fsl_udc: fix the usage of udc->max_ep
The max_ep is the number of endpoint * 2.
But in dtd_complete_irq, it does again * 2, it will deference wrong memory
after scanning max_ep - 1.
The another similar problem is at USB_REQ_SET_FEATURE (the pipe number
should be 0 and max_ep - 1).

usb: gadget: rename usb_gadget_driver::speed to max_speed
This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”. This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.
This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures. All
of those represent the *maximal* speed given entity supports.
After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
supports, and
* usb_composite_driver::max_speed - maximal speed composite
gadget supports.

usb: udc: Fix gadget driver's speed check in various UDC drivers
Several UDC drivers had a gadget driver's speed sanity check of the
form of:
driver->speed != USB_SPEED_HIGH
or:
driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL
As more and more gadget drivers support USB SuperSpeed, driver->speed
may be set to USB_SPEED_SUPER and UDC driver should handle such gadget
correctly. The above checks however fail to recognise USB_SPEED_SUPER
as a valid speed.
This commit changes the two checks to:
driver->speed < USB_SPEED_HIGH
or:
driver->speed < USB_SPEED_FULL
respectively.

Below are codes for accessing usb sysif_regs in driver:
usb_sys_regs = (struct usb_sys_interface *)
((u32)dr_regs + USB_DR_SYS_OFFSET);
these codes work in 32-bit, but in 64-bit, use u32 to type cast the address
of ioremap is not right, and accessing members of 'usb_sys_regs' will cause
call trace, so use (void *) for both 32-bit and 64-bit.

usb: Provide usb_speed_string() function
In a few places in the kernel, the code prints
a human-readable USB device speed (eg. "high speed").
This involves a switch statement sometimes wrapped
around in ({ ... }) block leading to code repetition.
To mitigate this issue, this commit introduces
usb_speed_string() function, which returns
a human-readable name of provided speed.
It also changes a few places switch was used to use
this new function. This changes a bit the way the
speed is printed in few instances at the same time
standardising it.

USB: fsl_udc_core: fix build breakage when building for ARM arch
Commit 09ba0def (USB: fsl_udc_core: prepare for SoCs with
BE registers and descriptors) introduced build breakage
on ARM arch. Fix it by setting accessors using a static
inline function which is a nop when compiling the driver
for ARM arch.
Commit 2ea6698 (USB: fsl_udc_core: support device mode of
MPC5121E DR USB Controller) caused another breakage on ARM
by using flush_dcache_range(). Don't use it, convert to the
DMA API usage instead. USB2.0CV Halt Endpoint Test succeeds
on PPC. Tested both on ARM i.MX31 and mpc5121 PPC, also with
CONFIG_DMA_API_DEBUG enabled.

fsl/usb: Unused endpoint failure for USB gadget
Though USB controller works without this most of the time, an issue was faced
where USB was configured as printer device and it was dropping first
packet(64 bytes) in full speed mode due to DATA PID mismatch.
The problem gets resolved once unused endpoints are configured as bulk.
As per P1020 RM (Table17-31, bits 19-18, bits 3-2) "When only one endpoint
(RX or TX, but not both) of an endpoint pair is used, the unused endpoint
should be configured as a bulk type endpoint." So according to the RM,
this patch is initializing TX and RX endpoints as bulk type

USB: fsl_udc_core: support device mode of MPC5121E DR USB Controller
Extend the FSL UDC driver to support MPC5121E DR USB Controller
operation in device mode. Add MPC5121E specific init/uninit
at probe and remove and isolate system interface register accesses
when running on MPC5121E SoC, as these registers are not available
on this platform. This patch relies on previous patch for supporting
big endian registers and descriptors access in the FSL UDC driver.
Additionally support endpoint FIFO status operation by providing
appropriate callback in endpoint ops structure.
Also flush cache for the req buffer used for GetStatus reply.
Without this, the correct reply to an endpoint GetStatus
is written to 'req', but doesn't make it out to the USB bus
since the buffer hasn't been flushed. This would cause the
USBCV Halt Endpoint test to fail (according to changelog in
Freescale LTIB driver code).

On some SoCs, the USB controller registers and descriptors can be big

able to run the same kernel binary on different versions of an SoC, the
BE/LE decision must be made at run time. Provide appropriate register

configuration flags from fsl_usb2_platform_data data structure.
This is in preparation for adding support for MPC5121E DR USB2 Controller

USB: fsl_udc_core: Fix kernel oops on module removal
fsl_udc_release() calls dma_free_coherent() with an inappropriate
device passed to it, and since the device has no dma_ops, the following
oops pops up:
Kernel BUG at d103ce9c [verbose debug info unavailable]
Oops: Exception in kernel mode, sig: 5 [#1]
...
NIP [d103ce9c] fsl_udc_release+0x50/0x80 [fsl_usb2_udc]

This patch fixes the issue by passing dev->parent, which points to
a correct device.

USB: gadget: Add i.MX3x support to the fsl_usb2_udc driver
This patch adds support for i.MX3x (only tested with i.MX31 so far) ARM
SoCs to the fsl_usb2_udc driver. It also moves PHY configuration before
controller reset, because otherwise an ULPI PHY doesn't get a reset and
doesn't function after a reboot. The problem with longer control transfers
is still not fixed. The patch renames the fsl_usb2_udc.c file to
fsl_udc_core.c to preserve the same module name for user-space
backwards compatibility.
