Make sure to deregister the controller before disabling it during driver
unbind.
Note that clocks were also disabled before the recent commit
1f8fd9490e31 ("spi: zynq-qspi: Simplify clock handling with
devm_clk_get_enabled()").

Note that the controller is suspended before disabling and releasing

transfer complete
The WARN_ON_ONCE/WARN_ON fired unconditionally on any completion
timeout, including the recoverable case where the interrupt was lost but
the hardware actually finished the transfer. This produced a noisy splat
with a full call trace even though the driver successfully recovered via
tegra_qspi_handle_timeout().
Since tegra210 uses threaded interrupts, the transfer completion can be
signaled before the interrupt fires, making this false positive case
common in practice.
Almost all the hosts I sysadmin in my fleet produce the following splat:
WARNING: CPU: 47 PID: 844 at drivers/spi/spi-tegra210-quad.c:1226 tegra_qspi_transfer_one_message+0x8a4/0xba8
....
tegra-qspi NVDA1513:00: QSPI interrupt timeout, but transfer complete
Move WARN_ON_ONCE/WARN_ON to fire only on real unrecoverable timeouts,
i.e., when tegra_qspi_handle_timeout() confirms the hardware did NOT
complete. This makes the warning actionable instead of just polluting
the metrics.

Prabhakar <prabhakar.csengg@gmail.com> says:
This patch series addresses three issues in the RZV2H RSPI driver:
1. The max_speed_hz field was advertising a prohibited bit rate, which
could lead to incorrect behavior when userspace applications attempt
to set the SPI clock speed.
2. The clock configuration logic allowed for an invalid combination of
SPR=0 and BRDV=0, which is not supported by the hardware.
3. Simplified the clock rate search function as min/max speed parameters
are not needed.
Note, patches apply on top of next-20260409.
|
|
The spr_min and spr_max parameters passed to
rzv2h_rspi_find_rate_variable() and rzv2h_rspi_find_rate_fixed() were
always called with RSPI_SPBR_SPR_MIN and RSPI_SPBR_SPR_MAX respectively.
There is no need to pass these as parameters since the valid SPR range
is fixed by the hardware.

The combination of SPR=0 and BRDV=0 results in the minimum division
ratio of 2, producing the maximum possible bit rate for a given clock
source. This combination is not supported in two cases:
- On RZ/G3E, RZ/G3L, RZ/V2H(P) and RZ/V2N, RSPI_n_TCLK is fixed at
200MHz, which would yield 100Mbps. The next hardware manual update
will explicitly state that since the maximum frequency of the
RSPICKn clock signal is 50MHz, settings with N=0 and n=0 resulting
in 100Mbps are prohibited.
- On RZ/T2H and RZ/N2H, when PCLK (125MHz) is used as the clock
source, SPR=0 and BRDV=0 is explicitly listed as unsupported in
the hardware manual (Table 36.7).
Skip the SPR=0/BRDV=0 combination in rzv2h_rspi_find_rate_fixed() to
prevent the driver from selecting an invalid clock configuration on the
affected SoCs.
Additionally, remove the now redundant RSPI_SPBR_SPR_PCLK_MIN define
which was previously set to 1 to work around the PCLK restriction, but
was overly broad as it incorrectly blocked valid combinations such as
SPR=0/BRDV=1 (31.25Mbps on PCLK=125MHz).
Fixes: 8b61c8919dff ("spi: Add driver for the RZ/V2H(P) RSPI IP")

On RZ/V2H(P), RZ/G3E and RZ/G3L, RSPI_n_TCLK is fixed at 200MHz.
The max_speed_hz was computed using clk_round_rate(tclk, ULONG_MAX)
with SPR=0 and BRDV=0, resulting in 100Mbps - the exact combination
prohibited on these SoCs. This could cause the SPI framework to request
a speed that rzv2h_rspi_find_rate_fixed() would skip, potentially
leading to a clock selection failure.
On RZ/T2H and RZ/N2H the max_speed_hz was correctly calculated as
50Mbps for both the variable PCLKSPIn and fixed PCLK clock sources.
Since the maximum supported bit rate is 50Mbps across all supported SoC
variants, replace the clk_round_rate() based calculation with a define
RSPI_MAX_SPEED_HZ set to 50MHz and use it directly for max_speed_hz.

The bindings describe the OTG enable GPIO as optional, but the driver
gets upset if it's not provided in the device tree.
Make the driver accept the absence of the GPIO, and just use register
writes to handle OTG mode in that case, skipping the error message for
-ENOENT.

Add __regmap_init_i3c() and the corresponding regmap_init_i3c() macro to
allow creating a regmap for I3C devices without using the device-managed
version. This mirrors the pattern already established for other buses
such as I2C, SPI and so on, giving drivers more flexibility when
the regmap lifetime is not directly tied to the device.

Mario Limonciello)
- Fix sysfs files being present when HW missing and broken/outdated
documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)

leads to a scheduling-while-atomic bug (K Prateek Nayak)
- Clean up dead code in Kconfig for cpufreq (Julian Braha)

boost_freq_req QoS request to save the boost constraint instead of
overwriting the last scaling_max_freq constraint (Pierre Gondois)

are allocated in one go along with the policy to simplify lifetime
rules and avoid error handling issues (Viresh Kumar)
- Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
scaling driver (Henry Tseng)

In current linux.git, gnttab_suspend() and gnttab_resume() are defined
and declared unconditionally. However, their only in-tree callers reside
in drivers/xen/manage.c, which are guarded by CONFIG_HIBERNATE_CALLBACKS.
Match the helper scope to their callers by wrapping the definitions in
CONFIG_HIBERNATE_CALLBACKS and providing no-op stubs in the header. This
fixes the config-scope mismatch and reduces the code footprint when
hibernation callbacks are disabled.

When the console out buffer is filled, __write_console() will return 0
as it cannot send any data. domU_write_console() will then spin in
`while (len)` as len doesn't decrement until xenconsoled attaches. This
would block a domU and nullify the parallelism of Hyperlaunch until dom0
userspace starts xenconsoled, which empties the buffer.
Xen 4.21 added a connection field to the xen console page. This is set
to XENCONSOLE_DISCONNECTED (1) when a domain is built, and xenconsoled
will set it to XENCONSOLE_CONNECTED (0) when it connects.
Update the hvc_xen driver to check the field. When the field is
disconnected, drop the write with -ENOTCONN. We only drop the write
when the field is XENCONSOLE_DISCONNECTED (1) to try for maximum
compatibility. The Xen toolstack has historically zero initialized the
console, so it should see XENCONSOLE_CONNECTED (0) by default. If an
implemenation used uninitialized memory, only checking for
XENCONSOLE_DISCONNECTED could have the lowest chance of not connecting.
This lets the hyperlaunched domU boot without stalling. Once dom0
starts xenconsoled, xl console can be used to access the domU's hvc0.
Paritally sync console.h from xen.git to bring in the new field.

Commit af85de5a9f00 ("xen: swiotlb: Switch to physical
address mapping callbacks") renamed xen_swiotlb_unmap_page()
to xen_swiotlb_unmap_phys(). The comment in
xen_swiotlb_unmap_sg() had already been missing the xen_
prefix (reading swiotlb_unmap_page()), and the rename only
changed _page to _phys without correcting this, leaving it
as swiotlb_unmap_phys(). Fix the reference to use the
correct function name xen_swiotlb_unmap_phys().

setup_shutdown_watcher() registers shutdown_watch first, then the sysrq
watch, and finally publishes the supported feature-* nodes in xenstore.
If sysrq watch registration fails, or xenbus_printf() fails after one or
more feature nodes were created, the function returns immediately without
undoing the earlier setup.
This leaves the system in a partially initialized state, with registered
watches and/or stale xenstore entries despite the function reporting
failure.
Unwind the partial setup before returning an error by unregistering any
watches that were already registered and removing feature nodes that were
already published.

fbnic_up() calls netif_tx_start_all_queues(), which only clears
__QUEUE_STATE_DRV_XOFF. If qdisc backlog has accumulated on any TX
queue before the reconfiguration (e.g. ring resize via ethtool -G),
start does not call __netif_schedule() to kick the qdisc, so the
pending backlog is never drained and the queue stalls.
Switch to netif_tx_wake_all_queues(), which clears DRV_XOFF and also
calls __netif_schedule() on every queue, ensuring any backlog that
built up before the down/up cycle is promptly dequeued.
