Currently cleaned_count is initialized to ICE_DESC_UNUSED(rx_ring) and
later on during the Rx processing it is incremented per each frame that
driver consumed. This can result in excessive buffers requested from xsk
pool based on that value.
To address this, just drop cleaned_count and pass
ICE_DESC_UNUSED(rx_ring) directly as a function argument to
ice_alloc_rx_bufs_zc(). Idea is to ask for buffers as many as consumed.
Let us also call ice_alloc_rx_bufs_zc unconditionally at the end of
ice_clean_rx_irq_zc. This has been changed in that way for corresponding
ice_clean_rx_irq, but not here.

Commit ac6f733a7bd5 ("ice: allow empty Rx descriptors") stated that ice
HW can produce empty descriptors that are valid and they should be

The descriptor that ntu is pointing at when we exit
ice_alloc_rx_bufs_zc() should not have its corresponding DD bit cleared
as descriptor is not allocated in there and it is not valid for HW
usage.
The allocation routine at the entry will fill the descriptor that ntu
points to after it was set to ntu + nb_buffs on previous call.
Even the spec says:
"The tail pointer should be set to one descriptor beyond the last empty
descriptor in host descriptor ring."
Therefore, step away from clearing the status_error0 on ntu + nb_buffs
descriptor.

The 'if (ntu == rx_ring->count)' block in ice_alloc_rx_buffers_zc()
was previously residing in the loop, but after introducing the
batched interface it is used only to wrap-around the NTU descriptor,
thus no more need to assign 'xdp'.

Currently, the zero-copy data path is reusing the memory region that was
initially allocated for an array of struct ice_rx_buf for its own
purposes. This is error prone as it is based on the ice_rx_buf struct
always being the same size or bigger than what the zero-copy path needs.
There can also be old values present in that array giving rise to errors
when the zero-copy path uses it.
Fix this by freeing the ice_rx_buf region and allocating a new array for
the zero-copy path that has the right length and is initialized to zero.

Currently we only NULL the xdp_buff pointer in the internal SW ring but
we never give it back to the xsk buffer pool. This means that buffers
can be leaked out of the buff pool and never be used again.
Add missing xsk_buff_free() call to the routine that is supposed to
clean the entries that are left in the ring so that these buffers in the
umem can be used by other sockets.
Also, only go through the space that is actually left to be cleaned
instead of a whole ring.

Play a video on the raven (or PCO, raven2) platform, and then do the S3
test. When resume, the following error will be reported:
amdgpu 0000:02:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring
vcn_dec test failed (-110)
[drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block

amdgpu 0000:02:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110
[why]
When playing the video: The power state flag of the vcn block is set to
POWER_STATE_ON.
When doing suspend: There is no change to the power state flag of the
vcn block, it is still POWER_STATE_ON.
When doing resume: Need to open the power gate of the vcn block and set
the power state flag of the VCN block to POWER_STATE_ON.
But at this time, the power state flag of the vcn block is already
POWER_STATE_ON. The power status flag check in the "8f2cdef drm/amd/pm:
avoid duplicate powergate/ungate setting" patch will return the
amdgpu_dpm_set_powergating_by_smu function directly.
As a result, the gate of the power was not opened, causing the
subsequent ring test to fail.
[how]
In the suspend function of the vcn block, explicitly change the power
state flag of the vcn block to POWER_STATE_OFF.

The job embedded fence donesn't initialize the flags at

once we enabled the trace event here. So introduce new amdgpu_fence

The USB2.0 spec chapter 11.24.2.13 says that the USB port which is going
under test needs to be put in suspend state before sending the test
command. Many hubs, don't enforce this precondition and they work fine
without this step. We should follow the specification and put the USB
port in suspend before sending the test command.
Also there are some "special" hubs, which requires to disable the USB
port power instead of putting it in suspend. I found out only three hubs
which requires this step, but if more are found, they can be added to
the list.
Since this changes the default implementation, it raises the posibility
of finding other broken hubs which are not compliant with the spec and
the test command might not work is the port is suspended. If such hubs
are found, a similar workaround like the disable part can be implemented
to skip putting the port in suspend.

The musb glue drivers just copy the glue resources to the musb child device.
Instead, set the musb child device's DT node pointer to the parent device's
node so that platform_get_irq_byname() can find the resources in the DT.
This removes the need for statically populating the IRQ resources from the
DT which has been deprecated for some time.

USB 3.2 spec, 9.2.5.4 "Changing Function Suspend State" says that "If
the link is in a non-U0 state, then the device must transition the link
to U0 prior to sending the remote wake message", but the hub only
transits the link to U0 after signaling remote wakeup.
So be more forgiving and use a 20ms delay to let the link transit to U0
for remote wakeup.

Override enable bits may not be restored when going to low power mode
(e.g. when in DWC2_POWER_DOWN_PARAM_NONE).
These bits are set when probing/initializing drd (role switch). Restore
them upon resume from low power mode (in case these have been lost).
To achieve this, the last known role is restored upon resume. And the
override enable bits are always set when configuring aval, bval and vbval.
When resuming, forcing the role should be done only once, or this can cause
port changes in HOST mode for instance.
So, only restore FORCEDEVMODE/FORCEHOSTMODE when role_sw is unused

The ChipIdea glue drivers just copy the glue resources to the "ci_hdrc"
child device. Instead, set the child device's DT node pointer to the
parent device's node so that platform_get_irq() can find the IRQ
resources in the DT. This removes the need for statically populating the
IRQ resources from the DT which has been deprecated for some time.

This reverts commit 796eed4b2342c9d6b26c958e92af91253a2390e1.
This change causes boot lockups when using "arlyprintk=xdbc" because
ktime can not be used at this point in time in the boot process. Also,
it is not needed for very small delays like this.

The Thumb2 version of the FP exception handling entry code treats the
register holding the CP number (R8) differently, resulting in the iWMMXT
CP number check to be incorrect.
Fix this by unifying the ARM and Thumb2 code paths, and switch the
order of the additions of the TI_USED_CP offset and the shifted CP
index.

The existing values are rejected by the da9063 regulator driver, as they
are unachievable with the declared chip setup (non-merged vcore and bmem
are unable to provide the declared curent).
Fix voltages to match rev3 schematics, which also matches their boot-up
configuration within the chip's available precision.
Declare bcore1/bcore2 and bmem/bio as merged.
Set ldo09 and ldo10 as always-on as their consumers are not declared but
exist.
Drop ldo current limits as there is no current limit feature for these
regulators in the DA9063. Fixes warnings like:
