msm_hdmi_get_phy() already prints error messages on each error path
using dev_err_probe(), so final DRM_DEV_ERROR() would duplicate it and
possibly flood the dmesg on probe deferrals.

Commit 384d2b03d0a1 ("drm/msm/hdmi: make use of the drm_connector_hdmi
framework") changed the unconditional register writes in few places to
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
registers.

There's a small window where the MDP clock could be set to a high rate
(say, from the bootloader) without a corresponding RPM(H)PD vote to
back it up. This is normally not an issue, but could be, if rmmod fails
to shut down the display driver cleanly, and the module is inserted
again, or when the providers' .sync_state has timed out.
Mark a TODO to fix it one day. Linking the relevant discussion below.

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.

To the best of my knowledge, the v1 version of this SoC had been
superseded before any device was released on the market. Everywhere
else in the kernel, there are assumptions about the SoC being revision
2 or the later MSM8974PRO.
Remove the config for that flavor of MDP. To bring the naming in line
with the rest of the kernel, remove the v2 suffix from the remaining
config.

EcoNet EN751221 clock/reset driver is significantly similar to the
EN7523 / EN7581, however the EN751221 does not have a neat batch of clock
divider registers so there are fewer known clocks, and the frequency of
each clock is derived differently. This clock driver will probably work
correctly on EN751627, EN7528, and EN7580.
