Ensure the TX descriptor type fields are published in a safe order so the
DMA engine never begins processing a descriptor chain before all descriptor
fields are fully initialised.
For multi-descriptor transmits the driver writes DT_FEND into the last
descriptor and DT_FSTART into the first. The DMA engine begins processing
when it observes DT_FSTART. Move the dma_wmb() barrier so it executes
immediately after DT_FEND and immediately before writing DT_FSTART
(and before DT_FSINGLE in the single-descriptor case). This guarantees
that all prior CPU writes to the descriptor memory are visible to the
device before DT_FSTART is seen.
This avoids a situation where compiler/CPU reordering could publish
DT_FSTART ahead of DT_FEND or other descriptor fields, allowing the DMA to
start on a partially initialised chain and causing corrupted transmissions
or TX timeouts. Such a failure was observed on RZ/G2L with an RT kernel as
transmit queue timeouts and device resets.

In the commit referenced by the Fixes tag, devm_clk_get_enabled() was
introduced to replace devm_clk_get() and clk_prepare_enable(). While
the clk_disable_unprepare() call in the error path was correctly
removed, the one in the remove function was overlooked, leading to a
double disable issue.
Remove the redundant clk_disable_unprepare() call from gsbi_remove()
to fix this issue. Since all resources are now managed by devres
and will be automatically released, the remove function serves no purpose
and can be deleted entirely.

System On Chip Control Processor (SOCCP) is a subsystem that can have
battery management firmware running on it to support Type-C/PD and
battery charging. SOCCP does not have multiple PDs and hence PDR is not
supported. So, if the subsystem comes up/down, rpmsg driver would be
probed or removed. Use that for notifying clients of pmic_glink for
PDR events.
Add support for battery management FW running on SOCCP by adding the
"PMIC_RTR_SOCCP_APPS" channel name to the rpmsg_match list and
updating notify_clients logic.

The USB4 HPG says this frequency remains unused, remove it from the
frequency table to avoid any misunderstandings.
The reason it's unused seems to be that the lower RPMh level required
to support it (LOW_SVS) is not enough for other pieces of the pipeline
which require SVS, which in turn is enough to support a faster, 175-ish
MHz rate.

DMC_EVT_CTL_ENABLE cannot be cleared once set. So currently
any event we never enable will have DMC_EVT_CTL_ENABLE cleared,
whereas any event which has been enabled even once will have
DMC_EVT_CTL_ENABLE set. For that reason assert_dmc_loaded() has
a special case to ignore any mismatches in DMC_EVT_CTL_ENABLE.
Eliminate the special case by always configuring DMC_EVT_CTL_ENABLE
based on the original firmware event definition. Now all
event handlers will have DMC_EVT_CTL_ENABLE set, whether or
not the event has been enabled in the past.
All disabled event handlers will still have the event type set
to DMC_EVENT_FALSE so they will not actually trigger despite
DMC_EVT_CTL_ENABLE being set.

TGL/ADL-S DMC firmware incorrectly uses the undelayed vblank
trigger for the HRR event, when it should be using the delayed
vblank trigger.
Fixed DMC firmware was never relaesed and isntead the Windows
driver just fixes this up by hand. Follow suit.
Not that we actually enable the HRR event currently. But let's
fix up the event ID, just in case someone ever needs to enable
this.

On ADL-S the main DMC HRR event DMC_EVT_CTL/HTP are never
restored to their previous values during DC6 exit. This
angers assert_dmc_loaded(), and basically makes the HRR
handler unusable because we don't rewrite EVT_HTP when
enabling DMC events.
Let's just clear the HRR EVT_CTL/HTP to zero from the
beginnning so that the expected value matches the post-DC6
reality.
I suppose if we ever had actual use for HRR we'd have to both,
reject HRR+PSR, and reprogram EVT_HTP when enabling the event.
But for now we don't care about HRR so keeping both registers
zeroed is fine.

While the user manual states that the PLL's rate should be between 180
MHz and 3 GHz in the register defninition section, it also says the
actual operating frequency is 22.5792*4 MHz in the PLL features table.
22.5792*4 MHz is one of the actual clock rates that we want and is
is available in the SDM table. Lower the minimum clock rate to 90 MHz
so that both rates in the SDM table can be used.

The "bus-r-dma" clock in the A523's PRCM clock controller is also
referred to as "DMA_CLKEN_SW" or "DMA ADB400 gating". It is unclear how
this ties into the DMA controller MBUS clock gate; however if the clock
is not enabled, the DMA controller in the MCU block will fail to access
DRAM, even failing to retrieve the DMA descriptors.
Mark this clock as critical. This sort of mirrors what is done for the
main DMA controller's MBUS clock, which has a separate toggle that is
currently left out of the main clock controller driver.

The intel_crtc_state::fec_enable check in intel_dp_needs_8b10b_fec() is
redundant drop it: originally it ensured that the FEC enabled state for
a CRTC other than the CRTC intel_dp_needs_8b10b_fec() called for is
preserved, even if DSC is not enabled for the latter CRTC. The way FEC
gets enabled for all the CRTCs on an 8b10b MST link is changed by
commit 7c027070e98d ("drm/i915/dp_mst: Track DSC enabled status on the
MST link") and
commit 470b84af457e ("drm/i915/dp_mst: Recompute all MST link CRTCs if
DSC gets enabled on the link")
depending on intel_dsc_enabled_on_link() in intel_dp_needs_8b10b_fec()
instead of the above fec_enable check. Drop the check.

Existing tools like myftm use 'legacy' test command API. Similarly
to ath11k and ath12k, we want to support raw TLV payload submitted
from the test tool. This requires segmenting the TLV payload and
encapsulating it within a WMI command. The opposite operation needs
to be done upon corresponding event receiving.
