drm/msm/dp: move parity calculation to dp_utils

2024-03-04T09:35:05+00:00

Parity calculation is necessary for VSC SDP implementation. Therefore create new files dp_utils.c and dp_utils.h and move the parity calculating functions here. This ensures that they are usable by SDP programming in both dp_catalog.c and dp_audio.c Changes in v3: - Change ordering of the header byte macros Changes in v2: - Create new files dp_utils.c and dp_utils.h - Move the parity calculation to these new files instead of having them in dp_catalog.c and dp_catalog.h Signed-off-by: Paloma Arellano Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/579617/ Link: https://lore.kernel.org/r/20240222194025.25329-13-quic_parellan@quicinc.com Signed-off-by: Dmitry Baryshkov

drm/msm/dp: drop dp_parser

2024-02-11T20:38:07+00:00

Finally drop separate "parsing" submodule. There is no need in it anymore. All submodules handle DT properties directly rather than passing them via the separate structure pointer.

drm/msm/dp: fold dp_power into dp_ctrl module

2024-02-11T20:38:07+00:00

The dp_power submodule is limited to handling the clocks only following previous cleanups. Fold it into the dp_ctrl submodule, removing one unnecessary level of indirection.

drm/msm/dpu: add dpu_hw_cdm abstraction for CDM block

2023-12-14T07:27:23+00:00

CDM block comes with its own set of registers and operations which can be done. In-line with other hardware blocks, this change adds the dpu_hw_cdm abstraction for the CDM block. changes in v4: - used FIELD_PREP() for dpu_hw_cdm_setup_cdwn() operations - change to lowercase hex in dpu_hw_cdm_bind_pingpong_blk() - move disable assignment inside else in dpu_hw_cdm_bind_pingpong_blk() changes in v3: - fix commit text from sub-blk to blk for CDM - fix kbot issue for missing static for dpu_hw_cdm_enable() - fix kbot issue for incorrect documentation style - add more documentation for enums and struct in dpu_hw_cdm.h - drop "enable" parameter from bind_pingpong_blk() as we can just use PINGPONG_NONE for disable cases - drop unnecessary bit operation for zero value of cdm_cfg changes in v2: - replace bit magic with relevant defines - use drmm_kzalloc instead of kzalloc/free - some formatting fixes - inline _setup_cdm_ops() - protect bind_pingpong_blk with core_rev check - drop setup_csc_data() and setup_cdwn() ops as they are merged into enable() Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202312101815.B3ZH7Pfy-lkp@intel.com/ Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/571824/ Link: https://lore.kernel.org/r/20231212205254.12422-8-quic_abhinavk@quicinc.com [DB: Added linux/bitfield.h inclusion] Signed-off-by: Dmitry Baryshkov

drm/msm: carve out KMS code from msm_drv.c

2023-10-09T18:51:48+00:00

The msm_drv.c contains generic code intermixed with KMS handling code. Move all KMS-related code to a separate msm_kms.c file, cleaning up init code while doing this move. This also prevents msm driver from registering modesetting / atomic interfaces in the headless case.
