These prints flood the logs with drm debugging set to enable kms and
driver logging (DRM_UT_KMS and DRM_UT_DRIVER). Let's move these prints
to the atomic bucket (DRM_UT_ATOMIC) as they're related to the atomic
paths.

These are verbose prints that tell us about the framebuffer state. Let's
move them to drm_dbg_state() so that they're only printed if we're
interested in verbose state logging while drm debugging.

Merge dpu_core_irq_enable() into dpu_core_irq_register_callback() and
dpu_core_irq_disable() into dpu_core_irq_unregister_callback(), because
they are called in pairs. There is no need to have separate

Let's look at the irq status bits after a transfer and see if we got a
nack or a defer or a timeout, instead of telling drm layers that
everything was fine, while still printing an error message. I wasn't
sure about NACK+DEFER so I lumped all those various errors along with a
nack so that the drm core can figure out that things are just not going
well. The important thing is that we're now returning -ETIMEDOUT when
the message times out and nacks for bad addresses.

irq_hpd interrupt should be handled after dongle plugged in and
before dongle unplugged. Hence irq_hpd interrupt is enabled at
the end of the plugin handle and disabled at the beginning of
unplugged handle. Current irq_hpd with sink_count = 0 is wrongly
handled same as the dongle unplugged which tears down the mainlink
and disables the phy. This patch fixes this problem by only tearing
down the mainlink but keeping phy enabled at irq_hpd with
sink_count = 0 handle so that next irq_hpd with sink_count =1 can be
handled by setup mainlink only. This patch also set dongle into D3
(power off) state at end of handling irq_hpd with sink_count = 0.

A problem was reported on CoachZ devices where the display wouldn't come
up, or it would be distorted. It turns out that the PLL code here wasn't
getting called once dsi_pll_10nm_vco_recalc_rate() started returning the
same exact frequency, down to the Hz, that the bootloader was setting
instead of 0 when the clk was registered with the clk framework.
After commit 001d8dc33875 ("drm/msm/dsi: remove temp data from global
pll structure") we use a hardcoded value for the parent clk frequency,
i.e. VCO_REF_CLK_RATE, and we also hardcode the value for FRAC_BITS,
instead of getting it from the config structure. This combination of
changes to the recalc function allows us to properly calculate the
frequency of the PLL regardless of whether or not the PLL has been
clk_prepare()d or clk_set_rate()d. That's a good improvement.
Unfortunately, this means that now we won't call down into the PLL clk
driver when we call clk_set_rate() because the frequency calculated in
the framework matches the frequency that is set in hardware. If the rate
is the same as what we want it should be OK to not call the set_rate PLL
op. The real problem is that the prepare op in this driver uses a
private struct member to stash away the vco frequency so that it can
call the set_rate op directly during prepare. Once the set_rate op is
never called because recalc_rate told us the rate is the same, we don't
set this private struct member before the prepare op runs, so we try to
call the set_rate function directly with a frequency of 0. This
effectively kills the PLL and configures it for a rate that won't work.
Calling set_rate from prepare is really quite bad and will confuse any
downstream clks about what the rate actually is of their parent. Fixing
that will be a rather large change though so we leave that to later.
For now, let's stash away the rate we calculate during recalc so that
the prepare op knows what frequency to set, instead of 0. This way
things keep working and the display can enable the PLL properly. In the
future, we should remove that code from the prepare op so that it
doesn't even try to call the set rate function.

Update CP_PROTECT register programming based on downstream.
A6XX_PROTECT_RW is renamed to A6XX_PROTECT_NORDWR to make things aligned
and also be more clear about what it does.
Note that this required switching to use the CP_ALWAYS_ON_COUNTER as the
GMU counter is not accessible from the cmdstream. Which also means
using the CPU counter for the msm_gpu_submit_flush() tracepoint (as
catapult depends on being able to compare this to the start/end values
captured in cmdstream). This may need to be revisited when IFPC is
enabled.
Also, compared to downstream, this opens up CP_PERFCTR_CP_SEL as the
userspace performance tooling (fdperf and pps-producer) expect to be
able to configure the CP counters.

Initialize audio_comp when audio starts and wait for audio_comp at
dp_display_disable(). This will take care of both dongle unplugged
and display off (suspend) cases.
Changes in v2:
-- add dp_display_signal_audio_start()
Changes in v3:
-- restore dp_display_handle_plugged_change() at dp_hpd_unplug_handle().
Changes in v4:
-- none

Link status is different from display connected status in the case
of something like an Apple dongle where the type-c plug can be
connected, and therefore the link is connected, but no sink is
connected until an HDMI cable is plugged into the dongle.
The sink_count of DPCD of dongle will increase to 1 once an HDMI
cable is plugged into the dongle so that display connected status
will become true. This checking also apply at pm_resume.
