drm/dp: Add max bpp delta computation constants

2026-06-24T03:57:33+00:00

Define macros used for decoding DSC max bpp delta values
from the sink DPCD. This includes per-format masks for
RGB/YCbCr444 and YCbCr420, as well as definitions for delta
scaling and the YCbCr420 bit shift. Also add version_1 as
suffix to MAX_DELTA_BPP.

v2: Move constants under 0x6E register. [Ankit]
    Add mask for Native 422 also. [Ankit]
v3: Rename _DSC_NATIVE4222 to _DSC_NATIVE_YCbCr422. [Ankit]
v4: Move Version_1 edit ti patch_1. [Ankit]
    Add shift mask for native also. [sashiko]

Rename DP_DSC_RGB_YCbCr420_MAX_BPP_DELTA_MASK to
DP_DSC_NATIVE_YCbCr420_MAX_BPP_DELTA_MASK to align with
the DP DSC specification, where the field represents the
native YCbCr 4:2:0 format.

The dsc max bpp delta masks were incorrectly placed
under the DP_DSC_BITS_PER_PIXEL_INC(0x06F) register.

drm/hdmi: Rename __drm_atomic_helper_connector_hdmi_reset()

2026-05-29T09:41:54+00:00

__drm_atomic_helper_connector_hdmi_reset() is typically used to
initialize a newly allocated drm_connector_state when the connector is
using the HDMI helpers, and is being called by the
drm_connector_funcs.reset implementation.

Since we want to consolidate DRM objects state allocation around the
atomic_create_state callback that will only allocate and initialize a
new drm_connector_state instance, we will need to call
__drm_atomic_helper_connector_hdmi_reset() from both the reset and
atomic_create hooks.

To avoid any confusion, we can thus rename
__drm_atomic_helper_connector_hdmi_reset() to
__drm_atomic_helper_connector_hdmi_state_init().

drm/dp: Store coasting vtotal in struct drm_dp_as_sdp

2026-05-11T08:58:46+00:00

Add new field in struct drm_dp_as_sdp to store coasting vtotal.
This is used by the sinks that support Panel Replay and Asynchronous
timing during PR Active to derive refresh rate, when AS SDP transmission
is stopped by the source.
