2025-09-08drm/i915/display: Remove FBC modulo 4 restriction for ADL-P+Uma Shankar
WA:22010751166 does not apply past display version 12. Or, in other words, the FBC restriction where FBC is disabled for non-modulo 4 plane sizes (including plane size + yoffset) is fixed from display version 13 and onwards. Relax the restriction for the same. v4: Dropped redundant commit message v3: Update comments for clarity (Jonathan Cavitt) v2: Update the macro for display version check (Vinod) Suggested-by: Vidya Srinivas <vidya.srinivas@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Reviewed-by: Vinod Govindapillai <vinod.govindapillai@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://lore.kernel.org/r/20250904095338.300813-2-uma.shankar@intel.com

The MISC protocol can provide System Manager (SM) configuration information, including platform identifiers and board-specific attributes.

The encoder name deduction has become a bit cumbersome within intel_ddi_init().

for_each_set_bit() expects size to be in bits, not bytes.

This controller's input and output logic is similar to previous generations of SoCs. Additionally, it's capable of interrupt masking, and could be configured to detect levels and edges, and is supplied with a distinct reset signal. The interrupt functionality is implemented through an irqchip, whose operations are written with previous generation SoCs in mind and could be reused. Since all Loongson SoCs with similar interrupt capability (LS2K1500, LS2K2000) support byte-control mode, these operations are for byte-control mode only for simplicity.

2025-09-08extcon: Add basic support for Maxim MAX14526 MUICSvyatoslav Ryhel
The MAX14526 is designed to simplify interface requirements on portable devices by multiplexing common inputs (USB, UART, Microphone, Stereo Audio and Composite Video) on a single micro/mini USB connector. The USB input supports Hi-Speed USB and the audio/video inputs feature negative rail signal operation allowing simple DC coupled accessories. These device allow a single micro/mini USB port to support all the common interfaces on Cellular phones and portable media players over the same external lines.

2025-09-08drm/i915/psr: Add poll for checking PSR is idle before starting updateJouni Högander
We are currently observing crc failures after we started using dsb for PSR updates as well. This seems to happen because PSR HW is still sending couple of updates using old framebuffers on wake-up. Fix this by adding poll ensuring PSR is idle before starting update. v2: pass new_crtc_state->dsb_commit to intel_psr_wait_for_idle_dsb Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://lore.kernel.org/r/20250905072708.2659411-5-jouni.hogander@intel.com
