cf868772dd usb: xhci: Add missing xhci_readl()
Accessing the xHCI controller registers should be done via the

f2e81c1d38 usb: musb: Ensure that we set musb dynamic FIFO buffer for every endpoint
If we do not set FIFO buffer address and size for some endpoint which is in
use then default programmed address 0x0 would be used which is in conflict
with address of FIFO buffer for endpoint 0. Moreover address of FIFO buffer
for endpoint 0 cannot be programmed, it is fixed to 0x0. Sharing address
space between more endpoints cause data loss and unexpected errors.

This patch is fixing transmission of characters over usbtty serial console
and allows using of usbtty for debugging purposes on Nokia N900.

f1e8d2072c usb: musb: Fix handling interrupts for EP0 and SET ADDRESS commmand
Interrupt for EP0 is indicated in intrtx register via first bit. This bit
is set for both RX and TX despite register has only TX in its name. First
bit in intrrx register is reserved, not used and never set.

So remove calling musb_peri_ep0() function at every iteration of udc_irq()
and musb_peri_rx() and call it only from musb_peri_tx() when correct
interrupt bit in initrtx it set.

Address from SET ADDRESS command must be set to faddr register only after
acknowledging SERV_RXPKTRDY followed by received EP0 interrupt. So prior
calling musb_peri_ep0_set_address() check for EP0 interrupt instead of
(incorrect) MUSB_INTR_SOF interrupt.

This patch fixes issue that host (computer) cannot register U-Boot USB
device and is failing with errors:

    usb 1-1: new full-speed USB device number 86 using xhci_hcd
    usb 1-1: Device not responding to setup address.
    usb 1-1: Device not responding to setup address.
    usb 1-1: device not accepting address 86, error -71

U-Boot was writing address to faddr register too early and did not wait for
correct interrupt after which should update address.

ff77bb301e usb: musb: Fix receiving of bigger buffers
If musb_peri_rx_ep() was called to process received HW buffer but U-Boot
cannot read it yet (e.g. because U-Boot SW buffer is full) then interrupt
was marked as processed also when HW buffer stayed unprocessed.

U-Boot tried to process this buffer again when it received interrupt again,
but it can receive it only when sender (host) sends a new data. As sender
(host) is not going to send a new data until U-Boot process current data
this issue caused a deadlock in case sender (host) is emitting data faster
than U-Boot can process it.

Reading musb intrrx register automatically clears this register and marks
interrupt as processed. So to prevent marking interrupt in U-Boot as
processed, adds a new variable pending_intrrx which would contain
unprocessed bits of intrrx register.

For a second step, every time when musb_peri_rx_ep() is called and there
are waiting data to be processed (signaled by MUSB_RXCSR_RXPKTRDY) either
acknowledge sender (via musb_peri_rx_ack()) that whole HW buffer was
processed or set corresponding bit in pending_intrrx that HW buffer was not
fully processed yet and next iteration is required after U-Boot allocates
space for reading HW buffer.

This patch fixes receiving large usb buffers, e.g. file transfer via Kermit
protocol implemented by 'loadb' U-Boot command over usbtty serial console.

ea7125c4c6 usb: musb: Fix transmission of bigger buffers
If udc_endpoint_write() was called with bigger payload which does not fit
into one USB packet it is needed to transmit payload in more USB packets.
First packet is transmitted by udc_endpoint_write() call itself and other
packets are put into waiting queue.

Implement function musb_peri_tx() which checks if endpoints are ready for
transmit and continue transmission of waiting queue.

10bc132510 usb: musb: Fix configuring FIFO for endpoints
This patch fixes configuring FIFOs for one-directional endpoints which have
only one queue (either RX or TX, but noth both).

Size of FIFO buffer is 2^(idx+3) bytes and starting address is 2^(addr+3).
Moreover first 64 bytes are reserved for EP0.

Without this patch if FIFO size specified by caller was zero then idx was
incorrectly calculated (expr. ffs(0)-1) and size overflowed in fifosz
register. This register uses has only 4 bits for FIFO size. Moreover
specifying zero buffer size is not possible (with idx=0 is minimal buffer
size 8 bytes).

So even for one-directional endpoints we need to correctly specify both
(RX and TX) FIFO buffer sizes and its addresses.

This patch is fixing calculation of start address and buffer size to
minimal value and ensures that it would not overlap with buffer reserved
for EP0.

This issue caused loose of packets on USB bus in both directions and
basically usbtty was unusable.

Since commit 8745b9ebcc ("usb: gadget: add super speed support")
ums was no more functional on platform which use dwc2_udc_otg driver.

This was due to a too restrictive test which checked that the gadget
driver speed was either FS or HS.

So all gadget driver with max speed set to speed higher than
HS (SS in case of composite gadget driver in our case) are not
allowed, which is wrong.

Update the speed test in usb_gadget_register_driver() and in
dwc2_gadget_start() to allow all gadget driver speed equal or higher
than FS.

Tested on stm32mp157c-ev1 board.

1a474559d9 xhci: translate virtual addresses into the bus's address space
So far we've been content with passing physical addresses when
configuring memory addresses into XHCI controllers, but not all
platforms have buses with transparent mappings. Specifically the
Raspberry Pi 4 might introduce an offset to memory accesses incoming
from its PCIe port.

Introduce xhci_virt_to_bus() and xhci_bus_to_virt() to cater with these
limitations, and make sure we don't break non DM users.

a764c94128 usb: gadget: OS Feature Descriptors support
This is a proting patch from linux kernel: 37a3a533429e
("usb: gadget: OS Feature Descriptors support"), the original commit
log see below:

There is a custom (non-USB IF) extension to the USB standard:

http://msdn.microsoft.com/library/windows/hardware/gg463182

They grant permission to use the specification - there is
"Microsoft OS Descriptor Specification License Agreement"
under the link mentioned above, and its Section 2 "Grant
of License", letter (b) reads:

"Patent license. Microsoft hereby grants to You a nonexclusive,
royalty-free, nontransferable, worldwide license under Microsoft鈥檚
patents embodied solely within the Specification and that are owned
or licensable by Microsoft to make, use, import, offer to sell,
sell and distribute directly or indirectly to Your Licensees Your
Implementation. You may sublicense this patent license to Your
Licensees under the same terms and conditions."

The said extension is maintained by Microsoft for Microsoft.

Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".

This patch adds optional support for gadgets whishing to expose
the so called "OS Feature Descriptors", that is "Extended Compatibility ID"
and "Extended Properties".

Hosts which do request "OS descriptors" from gadgets do so during
the enumeration phase and before the configuration is set with
SET_CONFIGURATION. What is more, those hosts never ask for configurations
at indices other than 0. Therefore, gadgets whishing to provide
"OS descriptors" must designate one configuration to be used with
this kind of hosts - this is what os_desc_config is added for in
struct usb_composite_dev. There is an additional advantage to it:
if a gadget provides "OS descriptors" and designates one configuration
to be used with such non-USB-compliant hosts it can invoke
"usb_add_config" in any order because the designated configuration
will be reported to be at index 0 anyway.

This patch also adds handling vendor-specific requests addressed
at device or interface and related to handling "OS descriptors"."

The said extension is maintained by Microsoft for Microsoft.

Yet it is fairly common for various devices to use it, and a
popular proprietary operating system expects devices to provide
"OS descriptors", so Linux-based USB gadgets whishing to be able
to talk to a variety of operating systems should be able to provide
the "OS descriptors".

This patch adds optional support for gadgets whishing to expose
the so called "OS String" under index 0xEE of language 0.
The contents of the string is generated based on the qw_sign
array and b_vendor_code.

Interested gadgets need to set the cdev->use_os_string flag,
fill cdev->qw_sign with appropriate values and fill cdev->b_vendor_code
with a value of their choice.

This patch does not however implement responding to any vendor-specific
USB requests."

change its name hence reset its ep num while do ep autoconfig, this is
only apply for SPL.

71a5732b43 usb: gadget: Add ep_config call back to usb_gadget_ops
Since some new fields in usb_ep structure been moved to usb_ss_ep.
The CDNS3 gadget driver should replies on this operation to bind the
usb_ss_ep with the endpoint descriptor when function layer uses
usb_ep_autoconfig to add endpoint descriptors to gadget. So that
CDNS3 driver can know the EP information and configure the EP once
the set configuration request is received.

Each array is used only in one file (core.c or ep0.c). Move their content
to correct file, mark them as static and do not export out of current file.

This change allows to decrease size of u-boot.bin as more of those strings
are not used.
