Hi Dave, Simona,
Pull for v6.15, as described below.
The following changes since commit 72d0af4accd965dc32f504440d74d0a4d18bf781:
drm/msm/dp: Add support for LTTPR handling (2025-02-25 18:34:14 +0200)

_dpu_encoder_trigger_start dereferences "struct dpu_encoder_phys *phys"
before the sanity checks which can lead to a NULL pointer dereference if
phys is NULL.
Fix this by reordering the dereference after the sanity checks.

HDMI standards define a recommended set of values to be used for Audio
Clock Regeneration. Nevertheless, each HDMI driver dealing with audio
implements its own way to determine those values. Implement a common
helper and use it for MSM HDMI (tested), VC4 and DW-HDMI (compile-tested
only) drivers.

Use drm_hdmi_acr_get_n_cts() helper instead of calculating N and CTS
values in the VC4 driver.

HDMI standard defines recommended N and CTS values for Audio Clock
Regeneration. Currently each driver implements those, frequently in
somewhat unique way. Provide a generic helper for getting those values
to be used by the HDMI drivers.
The helper is added to drm_hdmi_hel
From: Dmitry Baryshkov
Use new drm_hdmi_acr_get_n_cts() helper instead of hand-coding the
tables. Instead of storing the rate 'index', store the audio sample rate
in hdmi->audio.rate, removing the need for even more defines.
