The required clocks needs to be enabled before the first register
access. After commit fe8abf33 ("usb: dwc3: support clocks and resets
for DWC3 core"), this happens when the dwc3_core_is_valid function is
called, but the mentioned commit adds that call in the wrong place,
before the clocks are enabled. So, move that call after the
clk_bulk_enable() to ensure the clocks are enabled and the reset
deasserted.

I detected this while, as experiment, I tried to move the clocks and resets
from the glue layer to the DWC3 core on a Samsung Chromebook Plus.

That was not detected before because, in most cases, the glue layer
initializes SoC-specific things and then populates the child "snps,dwc3"
with those clocks already enabled.

dwc3_qcom_clk_init() is called with of_count_phandle_with_args() as an
argument.  If of_count_phandle_with_args() returns an error, the number
of clocks will be a negative value and will lead to undefined behaviour.

Ensure we check for an error before attempting to blindly use the value.

When booting with Device Tree, the current default boot configuration
table option, the request to boot via 'host mode' comes from the
'dr_mode' property.  A property of the same name can be used inside
ACPI tables too.  However it is missing from the SDM845's ACPI tables
so we have to supply this information using Platform Device Properties
instead.

This does not change the behaviour of any currently supported devices.
The property is only set on ACPI enabled platforms, thus for H/W
booting DT, unless a 'dr_mode' property is present, the default is
still OTG (On-The-Go) as per [0].  Any new ACPI devices added will
also be able to over-ride this implementation by providing a 'dr_mode'
property in their ACPI tables.  In cases where 'dr_mode' is omitted
from the tables AND 'host mode' should not be the default (very
unlikely), then we will have to add some way of choosing between them
at run time - most likely by ACPI HID.

In Linux, the DWC3 core exists as its own independent platform device.
Thus when describing relationships in Device Tree, the current default
boot configuration table option, the DWC3 core often resides as a child
of the platform specific node.  Both of which are given their own
address space descriptions and the drivers can be mostly agnostic to
each other.

However, other Operating Systems have taken a more monolithic approach,
which is evident in the configuration ACPI tables for the Qualcomm
Snapdragon SDM850, where all DWC3 (core and platform) components are
described under a single IO memory region.

To ensure successful booting using the supplied ACPI tables, we need to
devise a way to chop up the address regions provided and subsequently
register the DWC3 core with the resultant information, which is
precisely what this patch aims to achieve.

In some cases the "Allocate & copy" block in ffs_epfile_io() is not
executed. Consequently, in such a case ffs_alloc_buffer() is never called
and struct ffs_io_data is not initialized properly. This in turn leads to
problems when ffs_free_buffer() is called at the end of ffs_epfile_io().

This patch uses kzalloc() instead of kmalloc() in the aio case and memset()
in non-aio case to properly initialize struct ffs_io_data.

The following line of code in function ffs_epfile_io is trying to set
flag io_data->use_sg in case buffer required is larger than one page.

    io_data->use_sg = gadget->sg_supported && data_len > PAGE_SIZE;

However at this point of time the variable data_len has not been set
to the proper buffer size yet. The consequence is that io_data->use_sg
is always set regardless what buffer size really is, because the condition
(data_len > PAGE_SIZE) is effectively an unsigned comparison between
-EINVAL and PAGE_SIZE which would always result in TRUE.

If the 'snps,need-phy-for-wake' is set in the device tree then:

- We know that we can wakeup, so call device_set_wakeup_capable().
  The USB core will use this knowledge to enable wakeup by default.
- We know that we should keep the PHY on during suspend if something
  on our root hub needs remote wakeup.  This requires the patch (USB:
  Export usb_wakeup_enabled_descendants()).  Note that we don't keep
  the PHY on at suspend time if it's not needed because it would be a
  power draw.

If we later find some users of dwc2 that can support wakeup without
keeping the PHY on we may want to add a way to call
device_set_wakeup_capable() without keeping the PHY on at suspend
time.

NOTE: this is added specifically to veyron and not to rk3288 in

important rails in S3.

Also note that currently wakeup doesn't seem to happen unless you use
the "deep" suspend mode (where SDRAM is turned off).  Presumably the
shallow suspend mode is gating some sort of clock that's important but

 "The accumulated fixes from this and last week:

   - Fix vmalloc TLB flush and map range calculations which lead to
     stale TLBs, spurious faults and other hard to diagnose issues.

   - Use fault_in_pages_writable() for prefaulting the user stack in the
     FPU code as it's less fragile than the current solution

   - Use the PF_KTHREAD flag when checking for a kernel thread instead
     of current->mm as the latter can give the wrong answer due to
     use_mm()

   - Compute the vmemmap size correctly for KASLR and 5-Level paging.
     Otherwise this can end up with a way too small vmemmap area.

   - Make KASAN and 5-level paging work again by making sure that all
     invalid bits are masked out when computing the P4D offset. This
     worked before but got broken recently when the LDT remap area was
     moved.

   - Prevent a NULL pointer dereference in the resource control code
     which can be triggered with certain mount options when the
     requested resource is not available.

   - Enforce ordering of microcode loading vs. perf initialization on
     secondary CPUs. Otherwise perf tries to access a non-existing MSR
     as the boot CPU marked it as available.

   - Don't stop the resource control group walk early otherwise the
     control bitmaps are not updated correctly and become inconsistent.

   - Unbreak kgdb by returning 0 on success from
     kgdb_arch_set_breakpoint() instead of an error code.

   - Add more Icelake CPU model defines so depending changes can be
     queued in other trees"

The 5.1 mount system rework changed the smackfsdef mount option to
smackfsdefault.  This fixes the regression by making smackfsdef treated
the same way as smackfsdefault.

Also fix the smack_param_specs[] to have "smack" prefixes on all the
names.  This isn't visible to a user unless they either:

 (a) Try to mount a filesystem that's converted to the internal mount API
     and that implements the ->parse_monolithic() context operation - and
     only then if they call security_fs_context_parse_param() rather than
     security_sb_eat_lsm_opts().

     There are no examples of this upstream yet, but nfs will probably want
     to do this for nfs2 or nfs3.

 (b) Use fsconfig() to configure the filesystem - in which case
     security_fs_context_parse_param() will be called.

This issue is that smack_sb_eat_lsm_opts() checks for the "smack" prefix
on the options, but smack_fs_context_parse_param() does not.
