The second VBIF instance, VBIF_NRT, is only used for the separate inline
rotator block. It is unsupported by the DPU driver and will require a
separate driver (or separate instance of the DPU device).
The only possible user of VBIF_NRT is writeback on MSM8996, however
writeback on that platform is currently unsupported and it's not worth
keeping extra complexity for the sake of that single legacy platform.
None of the hardware catalogs entries actually declare VBIF_NRT, so it
is left in its default state.
Stop pretending that DPU driver cares about VBIF_NRT and drop it.

dpu_encoder_toggle_vblank_for_crtc() can call control_vblank_irq()
at any time in response to a userspace vblank request, independently
of the atomic commit sequence. If this happens before the encoder's
first atomic_mode_set(), irq[INTR_IDX_RDPTR] is still zero.
Passing irq_idx=0 to dpu_core_irq_register_callback() is treated as
invalid, and DPU_IRQ_REG(0) and DPU_IRQ_BIT(0) produce misleading
values of 134217727 and 31 respectively due to unsigned wraparound
in the (irq_idx - 1) macros, resulting in the confusing error:
[dpu error]invalid IRQ=[134217727, 31]
Since irq[INTR_IDX_RDPTR] will be properly populated by
atomic_mode_set() and registered by irq_enable() as part of the
normal modeset sequence, silently skip the vblank IRQ registration
when the index has not yet been initialized. This matches the
existing pattern of the master encoder check above it.

Commit 384d2b03d0 ("drm/msm/hdmi: make use of the drm_connector_hdmi

updates: read, apply mask, write. The new code reads
REG_HDMI_INFOFRAME_CTRL1 register, applies fields/mask for
HDMI_INFOFRAME_CTRL0 register and finally writes to
HDMI_INFOFRAME_CTRL0. This difference between CTRL1 and CTRL0 looks
unintended and may result in wrong data being written to HDMI bridge

During DPU runtime suspend, calling dev_pm_opp_set_rate(dev, 0) drops
the MMCX rail to MIN_SVS while the core clock frequency remains at its
original (highest) rate. When runtime resume re-enables the clock, this
may result in a mismatch between the rail voltage and the clock rate.
For example, in the DPU bind path, the sequence could be:
cpu0: dev_sync_state -> rpmhpd_sync_state
cpu1: dpu_kms_hw_init
timeline 0 ------------------------------------------------> t
After rpmhpd_sync_state, the voltage performance is no longer guaranteed
to stay at the highest level. During dpu_kms_hw_init, calling
dev_pm_opp_set_rate(dev, 0) drops the voltage, causing the MMCX rail to
fall to MIN_SVS while the core clock is still at its maximum frequency.
When the power is re-enabled, only the clock is enabled, leading to a
situation where the MMCX rail is at MIN_SVS but the core clock is at its
highest rate. In this state, the rail cannot sustain the clock rate,
which may cause instability or system crash.
Remove the call to dev_pm_opp_set_rate(dev, 0) from dpu_runtime_suspend
to ensure the correct vote is restored when DPU resumes.

three controllers only have two streams wired to the display subsystem,
while the fourth controller operates in single-stream mode.
Add a dedicated clause for the Glymur compatible to require the register
ranges for all four stream blocks, while allowing either one pixel clock
(for the single-stream controller) or two pixel clocks (for the remaining
controllers).
Update the Glymur MDSS schema example by adding the missing p2, p3,
mst2link and mst3link register blocks. Without these, the bindings
validation fails. Also replace the made-up register addresses with the
actual addresses from the first controller to match the SoC devicetree

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
This was previously fixed in this driver in commit 1ba9fbe403
