After removal of DPU_PLANE_QOS_VBLANK_CTRL, several fields of struct dpu_hw_pipe_qos_cfg are fixed to false/0. Drop them from the structure (and drop the corresponding code from the functions). The DPU_PLANE_QOS_VBLANK_AMORTIZE flag is also removed, since it is now a NOP.

The function dpu_plane_sspp_update_pipe() contains code to skip enabling the QoS and OT limitis for CURSOR pipes. However all DPU since sdm845 repurpose DMA SSPP for the cursor planes because they lack the real CURSOR SSPP. Fix the condition to actually check that the plane is CURSOR or not.

2023-05-22drm/msm/dpu: replace IS_ERR_OR_NULL with IS_ERR during DSC initDmitry Baryshkov
Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If the value is NULL, then the function will return 0 instead of a proper return code. Moreover dpu_hw_dsc_init() can not return NULL. Replace the IS_ERR_OR_NULL() call with IS_ERR(). This follows the commit 740828c73a36 ("drm/msm/dpu: fix error handling in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but then the commit f2803ee91a41 ("drm/msm/disp/dpu1: Add DSC support in RM") added it for DSC init.

2023-05-22drm/msm/dpu: Pass catalog pointers in RM to replace for-loop ID lookupsMarijn Suijten
The Resource Manager already iterates over all available blocks from the catalog, only to pass their ID to a dpu_hw_xxx_init() function which uses an _xxx_offset() helper to search for and find the exact same catalog pointer again to initialize the block with, fallible error handling and all. Instead, pass const pointers to the catalog entries directly to these _init functions and drop the for loops entirely, saving on both readability complexity and unnecessary cycles at boot.

2023-05-19drm/msm/dpu: use CTL_SC7280_MASK for sm8450's ctl_0Dmitry Baryshkov
On sm8450 platform the CTL_0 doesn't differ from the rest of CTL blocks, so switch it to CTL_SC7280_MASK too. Some background: original commit 100d7ef6995d ("drm/msm/dpu: add support for SM8450") had all (relevant at that time) bit spelled individually. Then commit 0e91bcbb0016 ("drm/msm/dpu: Add SM8350 to hw catalog"), despite being a mismerge, correctly changed all other CTL entries to use CTL_SC7280_MASK, except CTL_0. While the current BLOCK_SOC_MASK style is not ideal (and while we are working on a better scheme), let's follow its usage as a least minimal surprise. For example, sc8280xp, a close associate of sm8450, also uses CTL_SC7280_MASK.
