log: convert pr_*() to logging

2021-03-01T14:54:11+00:00

In drivers we use a family of printing functions including pr_err() and
pr_cont(). CONFIG_LOGLEVEL is used to control which of these lead to output
via printf().

Our logging functions allow finer grained control of output. So replace
printf() by the matching logging functions. The usage of CONFIG_LOGLEVEL
remains unchanged.

usb: gadget: OS Feature Descriptors support

2021-01-31T13:08:56+00:00

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 contents of the string is generated based on the qw_sign

fill cdev->qw_sign with appropriate values and fill cdev->b_vendor_code
with a value of their choice.

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.

smccc: fix sign bit expansion

2021-01-27T21:58:57+00:00

Signed ARM_SMCCC_FAST_CALL value is shifted to 31'st bit. Then, it is expanded
to 64 bit value, which results in 1s in higher 32 bits.

This causes corrupted values in 64-bit SMC IDs and issues in buggy handlers of
32-bit calls.

We need to make ARM_SMCCC_FAST_CALL unsigned long, so it would work properly
on 32 bit architectures.
