8844f467d6 drm/msm/dpu: make error messages at dpu_core_irq_register_callback() more sensible 
There is little point in using %ps to print a value known to be NULL. On
the other hand it makes sense to print the callback symbol in the
'invalid IRQ' message. Correct those two error messages to make more
sense.

	  that it is not dependent on if the dp_display is not eDP

Changes in v2:
	- Check for if dp_catalog has a CDM block available instead of

06267d22f9 drm/msm/dpu: Only enable DSC_MODE_MULTIPLEX if dsc_merge is enabled 
When the topology calls for two interfaces on the current fixed topology
of 2 DSC blocks, or uses 1 DSC block for a single interface (e.g. SC7280
with only one DSC block), there should be no merging of DSC output.

This is already represented by the return value of
dpu_encoder_use_dsc_merge(), but not yet used to correctly configure
this flag.

2f4a67a389 drm/msm/dpu: fix the programming of INTF_CFG2_DATA_HCTL_EN 
Currently INTF_CFG2_DATA_HCTL_EN is coupled with the enablement
of widebus but this is incorrect because we should be enabling
this bit independent of widebus except for cases where compression
is enabled in one pixel per clock mode.

Fix this by making the condition checks more explicit and enabling
INTF_CFG2_DATA_HCTL_EN for all other cases when supported by DPU.

858ddb64f1 drm/msm/dpu: improve DSC allocation 
At DSC V1.1 DCE (Display Compression Engine) contains a DSC encoder.
However, at DSC V1.2 DCE consists of two DSC encoders, one has an odd
index and another one has an even index. Each encoder can work
independently. But only two DSC encoders from same DCE can be paired
to work together to support DSC merge mode at DSC V1.2. For DSC V1.1
two consecutive DSC encoders (start with even index) have to be paired
to support DSC merge mode.  In addition, the DSC with even index have
to be mapped to even PINGPONG index and DSC with odd index have to be
mapped to odd PINGPONG index at its data path in regardless of DSC
V1.1 or V1.2. This patch improves DSC allocation mechanism with
consideration of those factors.

Changes in V6:
-- rename _dpu_rm_reserve_dsc_single to _dpu_rm_dsc_alloc
-- rename _dpu_rm_reserve_dsc_pair to _dpu_rm_dsc_alloc_pair
-- pass global_state to _dpu_rm_pingpong_next_index()
-- remove pp_max
-- fix for loop condition check at _dpu_rm_dsc_alloc()

Changes in V5:
-- delete dsc_id[]
-- update to global_state->dsc_to_enc_id[] directly
-- replace ndx with idx
-- fix indentation at function declaration
-- only one for loop at _dpu_rm_reserve_dsc_single()

Changes in V4:
-- rework commit message
-- use reserved_by_other()
-- add _dpu_rm_pingpong_next_index()
-- revise _dpu_rm_pingpong_dsc_check()

Changes in V3:
-- add dpu_rm_pingpong_dsc_check()
-- for pair allocation use i += 2 at for loop

Changes in V2:
    -- split _dpu_rm_reserve_dsc() into _dpu_rm_reserve_dsc_single() and
       _dpu_rm_reserve_dsc_pair()

	- 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()
