The Adreno GPU Management Unit (GMU) can also scale DDR Bandwidth along
the Frequency and Power Domain level, but by default we leave the
OPP core scale the interconnect ddr path.
While scaling via the interconnect path was sufficient, newer GPUs
like the A750 requires specific vote paremeters and bandwidth to
achieve full functionality.
In order to calculate vote values used by the GPU Management
Unit (GMU), we need to parse all the possible OPP Bandwidths and
create a vote value to be sent to the appropriate Bus Control
Modules (BCMs) declared in the GPU info struct.
This vote value is called IB, while on the other side the GMU also
takes another vote called AB which is a 16bit quantized value
of the floor bandwidth against the maximum supported bandwidth.
The AB vote will be calculated later when setting the frequency.
The vote array will then be used to dynamically generate the GMU
bw_table sent during the GMU power-up.

Log the version for informational purposes, such as for keeping track
of possible GMU fw-related failures in crash / CI logs.
Intentionally not implemented on the if (gmu->legacy) codepath, as
these registers seem not to be used on there.
Downstream additionally warns if the firmware version is too old for
a given GPU, but we already pair the binary to a given GPU, so let's
not go there at the moment.

Driver queries vport_cxt.num_plane and enables multiplane when it is
greater then 0, but some old FWs (versions from x.40.1000 till x.42.1000),
report vport_cxt.num_plane = 1 unexpectedly.

When ICSSG interfaces are brought down and brought up again, the
pru cores are shut down and booted again, flushing out all the memories
and start again in a clean state. Hence it is expected that the
IEP_CMP_CFG register needs to be flushed during iep_init() to ensure
that the existing residual configuration doesn't cause any unusual
behavior. If the register is not cleared, existing IEP_CMP_CFG set for
CMP1 will result in SYNC0_OUT signal based on the SYNC_OUT register values.
After bringing the interface up, calling PPS enable doesn't work as
the driver believes PPS is already enabled, (iep->pps_enabled is not
cleared during interface bring down) and driver will just return true
even though there is no signal. Fix this by disabling pps and perout.

Timesync related operations are ran in PRU0 cores for both ICSSG SLICE0
and SLICE1. Currently whenever any ICSSG interface comes up we load the
respective firmwares to PRU cores and whenever interface goes down, we
stop the resective cores. Due to this, when SLICE0 goes down while
SLICE1 is still active, PRU0 firmwares are unloaded and PRU0 core is
stopped. This results in clock jump for SLICE1 interface as the timesync
related operations are no longer running.
As there are interdependencies between SLICE0 and SLICE1 firmwares,
fix this by running both PRU0 and PRU1 firmwares as long as at least 1
ICSSG interface is up. Add new flag in prueth struct to check if all
firmwares are running and remove the old flag (fw_running).
Use emacs_initialized as reference count to load the firmwares for the
first and last interface up/down. Moving init_emac_mode and fw_offload_mode
API outside of icssg_config to icssg_common_start API as they need
to be called only once per firmware boot.
Change prueth_emac_restart() to return error code and add error prints
inside the caller of this functions in case of any failures.
Move prueth_emac_stop() from common to sr1 driver.
sr1 and sr2 drivers have different logic handling for stopping
the firmwares. While sr1 driver is dependent on emac structure
to stop the corresponding pru cores for that slice, for sr2
all the pru cores of both the slices are stopped and is not
dependent on emac. So the prueth_emac_stop() function is no
longer common and can be moved to sr1 driver.

ipc_mmio_init() used the post-decrement operator in its loop continuing
condition of "retries" counter being "> 0", which meant that when this
condition caused loop exit "retries" counter reached -1.
But the later valid exec stage failure check only tests for "retries"
counter being exactly zero, so it didn't trigger in this case (but
would wrongly trigger if the code reaches a valid exec stage in the
very last loop iteration).
Fix this by using the pre-decrement operator instead, so the loop counter
is exactly zero on valid exec stage failure.

In efx_tc_ct_zone_ht_params, the key_len was previously set to
offsetof(struct efx_tc_ct_zone, linkage). This calculation is incorrect
because it includes any padding between the zone field and the linkage
field due to structure alignment, which can vary between systems.
This patch updates key_len to use sizeof_field(struct efx_tc_ct_zone, zone)
, ensuring that the hash table correctly uses the zone as the key. This fix
prevents potential hash lookup errors and improves connection tracking
reliability.

This is a set of squashed commits to facilitate smooth applying to
stable. Each commit message is retained for reference.
1) Allow a GGTT mapped batch to be submitted to user exec queue
For a OA use case, one of the HW registers needs to be modified by
submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so
that the register is modified in the user's hardware context. In order
to do this a batch that is mapped in GGTT, needs to be submitted to the
user exec queue. Since all user submissions use q->vm and hence PPGTT,
add some plumbing to enable submission of batches mapped in GGTT.
v2: ggtt is zero-initialized, so no need to set it false (Matt Brost)
2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC
To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set.
Setting this bit cause the context image size to change and if not done
correct, can cause undesired hangs.
Current code uses a separate exec_queue to modify this bit and is
error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to
the target hardware context to modify the relevant bit.
In v2 version, an attempt to submit everything to the user-queue was
made, but it failed the unprivileged-single-ctx-counters test. It
appears that the OACTXCONTROL must be modified from a remote context.
In v3 version, all context specific register configurations were moved
to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a
cleaner way, since we can now submit all configuration to user
exec_queue and the fence handling is simplified.
v2:
(Matt)
- set job->ggtt to true if create job is successful
- unlock vm on job error
(Ashutosh)
- don't wait on job submission
- use kernel exec queue where possible
v3:
(Ashutosh)
- Fix checkpatch issues
- Remove extra spaces/new-lines
- Add Fixes: and Cc: tags
- Reset context control bit when OA stream is closed
- Submit all config via MI_LOAD_REGISTER_IMMEDIATE

- Update commit message for v3 experiment
- Squash patches for easier port to stable
v4:

- No need to pass q to xe_oa_submit_bb
- Do not support exec queues with width > 1
- Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE
v5:

- Drop reg_lri related comments
- Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri

SM8550/SM8650 SoCs
SM8550 and SM8650 SoCs doesn't support UFS PHY retention. So once these SoCs
reaches the low power state (CX power collapse) during system suspend, all
the PHY hardware state gets lost. This leads to the UFS resume failure:
ufshcd-qcom 1d84000.ufs: ufshcd_uic_hibern8_exit: hibern8 exit failed. ret = 5
ufshcd-qcom 1d84000.ufs: __ufshcd_wl_resume: hibern8 exit failed 5
ufs_device_wlun 0:0:0:49488: ufshcd_wl_resume failed: 5
ufs_device_wlun 0:0:0:49488: PM: dpm_run_callback(): scsi_bus_resume+0x0/0x84 returns 5
ufs_device_wlun 0:0:0:49488: PM: failed to resume async: error 5
With the default system suspend level of UFS_PM_LVL_3, the power domain for
UFS PHY needs to be kept always ON to retain the state. But this would
prevent these SoCs from reaching the CX power collapse state, leading to
poor power saving during system suspend.
So to fix this issue without affecting the power saving, set
'ufs_qcom_drvdata::no_phy_retention' to true which sets 'hba->spm_lvl' to
UFS_PM_LVL_5 to allow both the controller and device (in turn the PHY) to be
powered down during system suspend for these SoCs by default.

ufs_qcom_power_up_sequence()
PHY might already be powered on during ufs_qcom_power_up_sequence() in a
couple of cases:
1. During UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH quirk
2. Resuming from spm_lvl = 5 suspend
In those cases, it is necessary to call phy_power_off() and phy_exit() in
ufs_qcom_power_up_sequence() function to power off the PHY before calling
phy_init() and phy_power_on().
Case (1) is doing it via ufs_qcom_reinit_notify() callback, but case (2) is
not handled. So to satisfy both cases, call phy_power_off() and phy_exit()
if the phy_count is non-zero. And with this change, the reinit_notify()
callback is no longer needed.
This fixes the below UFS resume failure with spm_lvl = 5:

The DP calibration data is stored in nvmem cells, and the data layout is
described in the `mtk_dp_efuse_fmt` arrays for each platform.
There is no guarantee that the data is always a 4-length u32 cell array.
For example, MT8188 has a data length of 3, preventing it from passing
the preliminary check and undergoing calibration.
Update the logic to support flexible data lengths. Specifically, we
validate the length returned from `nvmem_cell_read()` against the
platform-specific efuse format. If out-of-bound access is detected, fall
back to the default calibration values. This likely indicates an error
in either the efuse data length described in DT or the efuse format
within the driver.

In all places the MI_STORE_DATA_IMM are not followed by a read of
the same memory address in the same batch buffer and the posted writes
are flushed with PIPE_CONTROL or MI_FLUSH_DW in xe_ring_ops.c functions
so there is no need to set this register.

Commit ba0925c34e0f ("gve: process XSK TX descriptors as part of RX NAPI")
moved XSK TX processing to be part of the RX NAPI. However, that commit
did not include triggering the RX NAPI in gve_xsk_wakeup. This is
necessary because the TX NAPI only processes TX completions, meaning
that a TX wakeup would not actually trigger XSK descriptor processing.
Also, the branch on XDP_WAKEUP_TX was supposed to have been removed, as
the NAPI should be scheduled whether the wakeup is for RX or TX.

The commit 3ab1663af6c1 ("watchdog: stm32_iwdg: Add pretimeout support")
introduces the support for the pre-timeout interrupt.
The support for this interrupt is optional but the driver uses the
platform_get_irq() which produces an error message during the driver
probe if we don't have any `interrupts` property in the DT.
Use the platform_get_irq_optional() API to get rid of the error message
as this property is optional.

Fix dp mode valid issue to avoid abnormal display of limit state.
After DP passes link training, it can express the lane count of the
current link status is good. Calculate the maximum bandwidth supported
by DP using the current lane count.
The color format will select the best one based on the bandwidth
requirements of the current timing mode. If the current timing mode
uses RGB and meets the DP link bandwidth requirements, RGB will be used.
If the timing mode uses RGB but does not meet the DP link bandwidthi
requirements, it will continue to check whether YUV422 meets
the DP link bandwidth.
FEC overhead is approximately 2.4% from DP 1.4a spec 2.2.1.4.2.
The down-spread amplitude shall either be disabled (0.0%) or up
to 0.5% from 1.4a 3.5.2.6. Add up to approximately 3% total overhead.
Because rate is already divided by 10,
mode->clock does not need to be multiplied by 10.
