Throughout the gpib drivers, a 'void *' struct member is used in place
of either port numbers or __iomem pointers, which leads to lots of extra
type casts, sparse warnings and less portable code.
Split the struct member in two separate ones with the correct types,
so each driver can pick which one to use.

The USB_GPIB_SET_LINES command string used to be: "\nIBDC \n" but when
we were merging this code into the upstream kernel we deleted the space
character before the newline to make checkpatch happy. That turned
out to be a mistake.
The "\nIBDC" part of the string is a command that we pass to the
firmware and the next character is a variable u8 value.
It gets set in set_control_line().
msg[leng - 2] = value ? (retval & ~line) : retval | line;
where leng is the length of the command string.
Imagine the parameter was supposed to be "8".
With the pre-merge code the command string would be "\nIBDC8\n"
With the post-merge code the command string became "\nIBD8\n"
The firmware doesn't recognize "IBD8" as a valid command and rejects it.
Putting a "." where the parameter is supposed to go fixes the driver
and makes checkpatch happy. Same thing with the other define and
the in-line assignment.

This patch fixes a number of consistency issues in the queue allocation
path related to XDP.
As it stands, the number of allocated XDP queues changes in three
different scenarios.
1) Adding an XDP program while the interface is up via
gve_add_xdp_queues
2) Removing an XDP program while the interface is up via
gve_remove_xdp_queues
3) After queues have been allocated and the old queue memory has been
removed in gve_queues_start.
However, the requirement for the interface to be up for
gve_(add|remove)_xdp_queues to be called, in conjunction with the fact
that the number of queues stored in priv isn't updated until _after_ XDP
queues have been allocated in the normal queue allocation path means
that if an XDP program is added while the interface is down, XDP queues
won't be added until the _second_ if_up, not the first.
Given the expectation that the number of XDP queues is equal to the
number of RX queues, scenario (3) has another problematic implication.
When changing the number of queues while an XDP program is loaded, the
number of XDP queues must be updated as well, as there is logic in the
driver (gve_xdp_tx_queue_id()) which relies on every RX queue having a
corresponding XDP TX queue. However, the number of XDP queues stored in
priv would not be updated until _after_ a close/open leading to a
mismatch in the number of XDP queues reported vs the number of XDP
queues which actually exist after the queue count update completes.
This patch remedies these issues by doing the following:
1) The allocation config getter function is set up to retrieve the
_expected_ number of XDP queues to allocate instead of relying
on the value stored in `priv` which is only updated once the queues
have been allocated.
2) When adjusting queues, XDP queues are adjusted to match the number of
RX queues when XDP is enabled. This only works in the case when
queues are live, so part (1) of the fix must still be available in
the case that queues are adjusted when there is an XDP program and
the interface is down.

When busy polling is enabled, xsk_sendmsg for AF_XDP zero copy marks
the NAPI ID corresponding to the memory pool allocated for the socket.
In GVE, this NAPI ID will never correspond to a NAPI ID of one of the
dedicated XDP TX queues registered with the umem because XDP TX is not
set up to share a NAPI with a corresponding RX queue.
This patch moves XSK TX descriptor processing from the TX NAPI to the RX
NAPI, and the gve_xsk_wakeup callback is updated to use the RX NAPI
instead of the TX NAPI, accordingly. The branch on if the wakeup is for
TX is removed, as the NAPI poll should be invoked whether the wakeup is
for TX or for RX.

This patch predicates the enabling and disabling of XSK pools on the
existence of queues. As it stands, if the interface is down, disabling
or enabling XSK pools would result in a crash, as the RX queue pointer
would be NULL. XSK pool registration will occur as part of the next
interface up.
Similarly, xsk_wakeup needs be guarded against queues disappearing
while the function is executing, so a check against the
GVE_PRIV_FLAGS_NAPI_ENABLED flag is added to synchronize with the
disabling of the bit and the synchronize_net() in gve_turndown.

In GVE, dedicated XDP queues only exist when an XDP program is installed
and the interface is up. As such, the NDO XDP XMIT callback should
return early if either of these conditions are false.
In the case of no loaded XDP program, priv->num_xdp_queues=0 which can
cause a divide-by-zero error, and in the case of interface down,
num_xdp_queues remains untouched to persist XDP queue count for the next
interface up, but the TX pointer itself would be NULL.
The XDP xmit callback also needs to synchronize with a device
transitioning from open to close. This synchronization will happen via
the GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call,
which waits for any RCU critical sections at call-time to complete.

When user enabled HDCP feature, userspace will set HDCP content
to DRM_MODE_CONTENT_PROTECTION_DESIRED. Next, anx7625 will update
HDCP content to DRM_MODE_CONTENT_PROTECTION_ENABLED if down stream
support HDCP feature.
As anx7625 bridge IC will be power down after call .atomic_disable(),
then all HDCP status will be lost on chip. So we should reestablish
HDCP again in .atomic_enable(), and update hdcp content to DESIRE if
current HDCP content is ENABLE in .atomic_disable().

original multiplier which is 4 as the second count is still 300 seconds
by default.
As the 20-bit number is now too large for practical use there is an option
to interpret it as microseconds instead of seconds.

The host_node pointer was assigned and freed in adv7533_parse_dt(), and
later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue
by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put()
in error path of probe() and also in the remove().

AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
- In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
before/after setting ADV7511_REG_AUDIO_INFOFRAME.
- In audio_startup() use the correct register for clearing
AUDIO_UPDATE bit.
The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.
Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

On the i.MX6ULL-14x14-EVK board, enet1_ref and enet2_ref are used as the
clock sources for two external KSZ PHYs. However, after closing the two
FEC ports, the clk_enable_count of the enet1_ref and enet2_ref clocks is
not 0. The root cause is that since the commit 985329462723 ("net: phy:
micrel: use devm_clk_get_optional_enabled for the rmii-ref clock"), the
external clock of KSZ PHY has been enabled when the PHY driver probes,
and it can only be disabled when the PHY driver is removed. This causes
the clock to continue working when the system is suspended or the network
port is down.
Although Heiko explained in the commit message that the patch was because
some clock suppliers need to enable the clock to get the valid clock rate
, it seems that the simple fix is to disable the clock after getting the
clock rate to solve the current problem. This is indeed true, but we need
to admit that Heiko's patch has been applied for more than a year, and we
cannot guarantee whether there are platforms that only enable rmii-ref in
the KSZ PHY driver during this period. If this is the case, disabling
rmii-ref will cause RMII on these platforms to not work.
Secondly, commit 99ac4cbcc2a5 ("net: phy: micrel: allow usage of generic
ethernet-phy clock") just simply enables the generic clock permanently,
which seems like the generic clock may only be enabled in the PHY driver.
If we simply disable the generic clock, RMII may not work. If we keep it
as it is, the platform using the generic clock will have the same problem
as the i.MX6ULL platform.
To solve this problem, the clock is enabled when phy_driver::resume() is
called, and the clock is disabled when phy_driver::suspend() is called.
Since phy_driver::resume() and phy_driver::suspend() are not called in
pairs, an additional clk_enable flag is added. When phy_driver::suspend()
is called, the clock is disabled only if clk_enable is true. Conversely,
when phy_driver::resume() is called, the clock is enabled if clk_enable
is false.
The changes that introduced the problem were only a few lines, while the
current fix is about a hundred lines, which seems out of proportion, but
it is necessary because kszphy_probe() is used by multiple KSZ PHYs and
we need to fix all of them.

dm_get_plane_scale doesn't take into account plane scaled size equal to
zero, leading to a kernel oops due to division by zero. Fix by setting
out-scale size as zero when the dst size is zero, similar to what is
done by drm_calc_scale(). This issue started with the introduction of
cursor ovelay mode that uses this function to assess cursor mode changes
via dm_crtc_get_cursor_mode() before checking plane state.

[WHY & HOW]
commit 7fb363c57522 ("drm/amd/display: Let drm_crtc_vblank_on/off manage interrupts")
lets drm_crtc_vblank_* to manage interrupts in amdgpu_dm_crtc_set_vblank,
and amdgpu_irq_get/put do not need to be called here. Part of that
patch got lost somehow, so fix it up.

If a PCIe port only supports a single speed, enabling bandwidth control
is pointless: There's no need to monitor autonomous speed changes, nor
can the speed be changed.
Not enabling it saves a small amount of memory and compute resources,
but also fixes a boot hang reported by Niklas: It occurs when enabling
bandwidth control on Downstream Ports of Intel JHL7540 "Titan Ridge 2018"
Thunderbolt controllers. The ports only support 2.5 GT/s in accordance
with USB4 v2 sec 11.2.1, so the present commit works around the issue.
PCIe r6.2 sec 8.2.1 prescribes that:
"A device must support 2.5 GT/s and is not permitted to skip support
for any data rates between 2.5 GT/s and the highest supported rate."
Consequently, bandwidth control is currently only disabled if a port
doesn't support higher speeds than 2.5 GT/s. However the Implementation
Note in PCIe r6.2 sec 7.5.3.18 cautions:
"It is strongly encouraged that software primarily utilize the
Supported Link Speeds Vector instead of the Max Link Speed field,
so that software can determine the exact set of supported speeds on
current and future hardware. This can avoid software being confused
if a future specification defines Links that do not require support
for all slower speeds."
In other words, future revisions of the PCIe Base Spec may allow gaps
in the Supported Link Speeds Vector. To be future-proof, don't just
check whether speeds above 2.5 GT/s are supported, but rather check
whether *more than one* speed is supported.

The Supported Link Speeds Vector in the Link Capabilities 2 Register
indicates the *supported* link speeds. The Max Link Speed field in the
Link Capabilities Register indicates the *maximum* of those speeds.
pcie_get_supported_speeds() neglects to honor the Max Link Speed field and
will thus incorrectly deem higher speeds as supported. Fix it.
One user-visible issue addressed here is an incorrect value in the sysfs
attribute "max_link_speed".
But the main motivation is a boot hang reported by Niklas: Intel JHL7540
"Titan Ridge 2018" Thunderbolt controllers supports 2.5-8 GT/s speeds,
but indicate 2.5 GT/s as maximum. Ilpo recalls seeing this on more
devices. It can be explained by the controller's Downstream Ports
supporting 8 GT/s if an Endpoint is attached, but limiting to 2.5 GT/s
if the port interfaces to a PCIe Adapter, in accordance with USB4 v2
sec 11.2.1:
"This section defines the functionality of an Internal PCIe Port that
interfaces to a PCIe Adapter. [...]
The Logical sub-block shall update the PCIe configuration registers
with the following characteristics: [...]
Max Link Speed field in the Link Capabilities Register set to 0001b
(data rate of 2.5 GT/s only).
Note: These settings do not represent actual throughput. Throughput
is implementation specific and based on the USB4 Fabric performance."
The present commit is not sufficient on its own to fix Niklas' boot hang,
but it is a prerequisite: A subsequent commit will fix the boot hang by
enabling bandwidth control only if more than one speed is supported.
The GENMASK() macro used herein specifies 0 as lowest bit, even though
the Supported Link Speeds Vector ends at bit 1. This is done on purpose
to avoid a GENMASK(0, 1) macro if Max Link Speed is zero. That macro
would be invalid as the lowest bit is greater than the highest bit.
Ilpo has witnessed a zero Max Link Speed on Root Complex Integrated
Endpoints in particular, so it does occur in practice. (The Link
Capabilities Register is optional on RCiEPs per PCIe r6.2 sec 7.5.3.)

Before, every time fdinfo is queried we try to lock all the BOs in the
VM and calculate memory usage from scratch. This works okay if the
fdinfo is rarely read and the VMs don't have a ton of BOs. If either of
these conditions is not true, we get a massive performance hit.
In this new revision, we track the BOs as they change states. This way
when the fdinfo is queried we only need to take the status lock and copy
out the usage stats with minimal impact to the runtime performance. With
this new approach however, we would no longer be able to track active
buffers.

When memory stats is generated fresh everytime by going though all the
BOs, their active information is quite easy to get. But if the stats are
tracked with BO's state this becomes harder since the job scheduling
part doesn't really deal with individual buffers.
Make drm-active- optional to enable amdgpu to switch to the second
method.
