Historically, the clocks and resets are handled on the glue layer
side instead of the DWC3 core. For simple cases, dwc3-of-simple.c
takes care of arbitrary number of clocks and resets. The DT node
structure typically looks like as follows:
dwc3-glue {
compatible = "foo,dwc3";
clocks = ...;
resets = ...;
...
dwc3 {
compatible = "snps,dwc3";
...
};
}
By supporting the clocks and the reset in the dwc3/core.c, it will
be turned into a single node:
dwc3 {
compatible = "foo,dwc3", "snps,dwc3";
clocks = ...;
resets = ...;
...
}
This commit adds the binding of clocks and resets specific to this IP.
The number of clocks should generally be the same across SoCs, it is
just some SoCs either tie clocks together or do not provide software
control of some of the clocks.
I took the clock names from the Synopsys datasheet: "ref" (ref_clk),
"bus_early" (bus_clk_early), and "suspend" (suspend_clk).
I found only one reset line in the datasheet, hence the reset-names
property is omitted.
Those clocks are required for new platforms. Enforcing the new
binding breaks existing platforms since they specify clocks (and
resets) in their glue layer node, but nothing in the core node.
I listed such exceptional cases in the DT binding. The driver
code has been relaxed to accept no clock. This change is based
on the discussion [1].
I inserted reset_control_deassert() and clk_bulk_enable() before the
first register access, i.e. dwc3_cache_hwparams().

DWC3 controller on Qualcomm SOCs has a Qscratch wrapper.
Some of its uses are described below resulting in need to
have a separate glue driver instead of using dwc3-of-simple:
- It exposes register interface to override vbus-override
and lane0-pwr-present signals going to hardware. These
must be updated in peripheral mode for DWC3 if vbus lines
are not connected to hardware block. Otherwise RX termination
in SS mode or DP pull-up is not applied by device controller.
- pwr_events_irq_stat support to check if USB2 PHY is in L2 state
before glue driver proceeds with suspend.
- Support for wakeup interrupts lines that are asserted whenever
there is any wakeup event on USB3 or USB2 bus.
- Support to replace pip3 clock going to DWC3 with utmi clock
for hardware configuration where SSPHY is not used with DWC3.

Changed existing two descriptor-chain flow to one chain.
In two-chain implementation BNA interrupt used for switching between
two chains. BNA interrupt asserted because of returning to
beginning of the chain based on L-bit of last descriptor.
Because of that we lose packets. This issue resolved by using one
desc-chain.
Removed all staff related to two desc-chain flow from
DDMA ISOC related functions.
Removed request length checking from dwc2_gadget_fill_isoc_desc()
function. Request length checking added to dwc2_hsotg_ep_queue()
function. If request length greater than descriptor limits then
request not added to queue. Additional checking done for High
Bandwidth ISOC OUT's which not supported by driver. In
dwc2_gadget_fill_isoc_desc() function also checked desc-chain
status (full or not) to avoid of reusing not yet processed
descriptors.
In dwc2_gadget_start_isoc_ddma() function creation of desc-chain
always started from descriptor 0. Before filling descriptors, they
were initialized by HOST BUSY status.
In dwc2_gadget_complete_isoc_request_ddma() added checking for
desc-chain rollover. Also added checking completion status.
Request completed successfully if DEV_DMA_STS is DEV_DMA_STS_SUCC,
otherwise complete with actual=0. For systems with high IRQ latency
added pointer compl_desc to next descriptor to be completed by
XferCompl interrupt. This pointer replace descriptor index calculation
based on DxEPDMA register. On descriptor completion interrupt
processing all descriptors starting from compl_desc till descriptor
which Buffer Status field not equal DMA_DONE status.
Actually removed dwc2_gadget_start_next_isoc_ddma() function because
now driver use only one desc-chain and instead that function added
dwc2_gadget_handle_isoc_bna() function for handling BNA interrupts.
Handling BNA interrupt done by flushing TxFIFOs for OUT EPs,
completing request with actual=0 and resetting desc-chain number and
target frame to initial values for restarting transfers.
On handling NAK request completed with actual=0. Incremented target
frame to allow fill desc chain and start transfers.
In DDMA mode avoided of frame number incrementing, because tracking
of frame number performed in dwc2_gadget_fill_isoc_desc() function.
When core assert XferCompl along with BNA, we should ignore XferCompl
in dwc2_hsotg_epint() function.
On BNA interrupt replaced dwc2_gadget_start_next_isoc_ddma() by above
mentioned BNA handler.
In dwc2_hsotg_ep_enable() function added sanity check of bInterval
for ISOC IN in DDMA mode, because HW doesn't supported EP's with
bInterval more than 10 and check for mc for ISOC OUT transfers,
because core doesn't support high bandwidth transfers.

When the xHCI driver set PORT_POWER of the OTG port, and if both
IDPIN and VBUS_VALID are high at the same time, the MTU3 controller
will set SESSION and pull up DP, so the Win7 can detect existence
of USB device, but if the mtu3 driver can't switch to device mode

The Aspeed BMC SoCs support a "virtual hub" function. It provides some
HW support for a top-level USB2 hub behind which sit 5 gadget "ports".
This driver adds support for the full functionality, emulating the
hub standard requests and exposing 5 UDC gadget drivers corresponding
to the ports.
The hub itself has HW provided dedicated EP0 and EP1 (the latter for
hub interrupts). It also has dedicated EP0s for each function. For
other endpoints, there's a pool of 15 "generic" endpoints that are
shared among the ports.
The driver relies on my previous patch adding a "dispose" EP op to
handle EP allocation between ports. EPs are allocated from the shared
pool in the UDC "match_ep" callback and assigned to the UDC instance
(added to the gadget ep_list).
When the composite driver gets unbound, the new hook will allow the UDC
to clean things up and return those EPs to the shared pool.

Pull perf fixes from Thomas Gleixner:
"A larger set of updates for perf.
Kernel:
- Handle the SBOX uncore monitoring correctly on Broadwell CPUs which
do not have SBOX.
- Store context switch out type in PERF_RECORD_SWITCH[_CPU_WIDE]. The
percentage of preempting and non-preempting context switches help
understanding the nature of workloads (CPU or IO bound) that are
running on a machine. This adds the kernel facility and userspace
changes needed to show this information in 'perf script' and 'perf
report -D' (Alexey Budankov)
- Remove a WARN_ON() in the trace/kprobes code which is pointless
because the return error code is already telling the caller what's
wrong.
- Revert a fugly workaround for clang BPF targets.
- Fix sample_max_stack maximum check and do not proceed when an error
has been detect, return them to avoid misidentifying errors (Jiri
Olsa)
- Add SPDX idenitifiers and get rid of GPL boilderplate.
Tools:
- Synchronize kernel ABI headers, v4.17-rc1 (Ingo Molnar)
- Support MAP_FIXED_NOREPLACE, noticed when updating the
tools/include/ copies (Arnaldo Carvalho de Melo)
- Add '\n' at the end of parse-options error messages (Ravi Bangoria)
- Add s390 support for detailed/verbose PMU event description (Thomas
Richter)
- perf annotate fixes and improvements:
* Allow showing offsets in more than just jump targets, use the
new 'O' hotkey in the TUI, config ~/.perfconfig
annotate.offset_level for it and for --stdio2 (Arnaldo Carvalho
de Melo)
* Use the resolved variable names from objdump disassembled lines
to make them more compact, just like was already done for some
instructions, like "mov", this eventually will be done more
generally, but lets now add some more to the existing mechanism
(Arnaldo Carvalho de Melo)
- perf record fixes:
* Change warning for missing topology sysfs entry to debug, as not
all architectures have those files, s390 being one of those
(Thomas Richter)
* Remove old error messages about things that unlikely to be the
root cause in modern systems (Andi Kleen)
- perf sched fixes:
* Fix -g/--call-graph documentation (Takuya Yamamoto)
- perf stat:
* Enable 1ms interval for printing event counters values in
(Alexey Budankov)
- perf test fixes:
* Run dwarf unwind on arm32 (Kim Phillips)
* Remove unused ptrace.h include from LLVM test, sidesteping older
clang's lack of support for some asm constructs (Arnaldo
Carvalho de Melo)
* Fixup BPF test using epoll_pwait syscall function probe, to cope
with the syscall routines renames performed in this development
cycle (Arnaldo Carvalho de Melo)
- perf version fixes:
* Do not print info about HAVE_LIBAUDIT_SUPPORT in 'perf version
--build-options' when HAVE_SYSCALL_TABLE_SUPPORT is true, as
libaudit won't be used in that case, print info about
syscall_table support instead (Jin Yao)
- Build system fixes:
* Use HAVE_..._SUPPORT used consistently (Jin Yao)
* Restore READ_ONCE() C++ compatibility in tools/include (Mark
Rutland)
* Give hints about package names needed to build jvmti (Arnaldo
Carvalho de Melo)"

Pull libnvdimm fixes from Dan Williams:
"A regression fix, new unit test infrastructure and a build fix:
- Regression fix addressing support for the new NVDIMM label storage
area access commands (_LSI, _LSR, and _LSW).
The Intel specific version of these commands communicated the
"Device Locked" status on the label-storage-information command.
However, these new commands (standardized in ACPI 6.2) communicate
the "Device Locked" status on the label-storage-read command, and
the driver was missing the indication.
Reading from locked persistent memory is similar to reading
unmapped PCI memory space, returns all 1's.
- Unit test infrastructure is added to regression test the "Device
Locked" detection failure.
- A build fix is included to allow the "of_pmem" driver to be built
as a module and translate an Open Firmware described device to its
local numa node"
