Fix the dp_panel_get_supported_bpp() API to return the minimum
supported bpp correctly for relevant cases and use this API
to correct the behavior of DP driver which hard-codes the max supported
bpp to 30.
This is incorrect because the number of lanes and max data rate
supported by the lanes need to be taken into account.
Replace the hardcoded limit with the appropriate math which accounts
for the accurate number of lanes and max data rate.
changes in v2:
- Fix the dp_panel_get_supported_bpp() and use it
- Drop the max_t usage as dp_panel_get_supported_bpp() already
returns the min_bpp correctly now
changes in v3:
- replace min_t with just min as all params are u32

The dp_audio read and write operations uses members in struct dp_catalog

Before the introduction of the wait_hpd_asserted() callback in
commit 841d742f09 ("drm/dp: Add wait_hpd_asserted() callback to struct
drm_dp_aux") the API between panel drivers and DP AUX bus drivers was
that it was up to the AUX bus driver to wait for HPD in the transfer()
function.
Now wait_hpd_asserted() has been added. The two panel drivers that are
DP AUX endpoints use it. See commit 2327b13d6c ("drm/panel-edp: Take
advantage of wait_hpd_asserted() in struct drm_dp_aux") and
commit 3b5765df37 ("drm/panel: atna33xc20: Take advantage of
wait_hpd_asserted() in struct drm_dp_aux"). We've implemented
wait_hpd_asserted() in the MSM DP driver as of commit e2969ee302
("drm/msm/dp: move of_dp_aux_populate_bus() to eDP probe()"). There is
no longer any reason for long wait in the AUX transfer() function.
Remove it.
NOTE: the wait_hpd_asserted() is listed as "optional". That means it's
optional for the DP AUX bus to implement. In the case of the MSM DP
driver we implement it so we can assume it will be called.
ALSO NOTE: the wait wasn't actually _hurting_ anything and wasn't even
causing long timeouts, but it's still nice to get rid of unneeded
code. Specificaly it's not truly needed because to handle other DP
drivers that can't power on as quickly (specifically parade-ps8640) we
already avoid DP AUX transfers for eDP panels that aren't powered
on. See commit 8df1ddb5bf ("drm/dp: Don't attempt AUX transfers when
eDP panels are not powered").

The DP wait_hpd_asserted() callback is passed a timeout which
indicates how long we should wait for HPD. This timeout was being
ignored in the MSM DP implementation and instead a hardcoded 500 ms
timeout was used. Fix it to use the proper timeout.
As part of this we move the hardcoded 500 ms number into the AUX
transfer function, which isn't given a timeout. The wait in the AUX
transfer function will be removed in a future commit.

As documented in the description of the transfer() function of
"struct drm_dp_aux", the transfer() function can be called at any time
regardless of the state of the DP port. Specifically if the kernel has
the DP AUX character device enabled and userspace accesses
"/dev/drm_dp_auxN" directly then the AUX transfer function will be
called regardless of whether a DP device is connected.
For eDP panels we have a special rule where we wait (with a 5 second
timeout) for HPD to go high. This rule was important before all panels
drivers were converted to call wait_hpd_asserted() and actually can be
removed in a future commit.
For external DP devices we never checked for HPD. That means that
trying to access the DP AUX character device (AKA `hexdump -C
/dev/drm_dp_auxN`) would very, very slowly timeout. Specifically on my
system:
$ time hexdump -C /dev/drm_dp_aux0
hexdump: /dev/drm_dp_aux0: Connection timed out
real 0m8.200s
We want access to the drm_dp_auxN character device to fail faster than
8 seconds when no DP cable is plugged in.
Let's add a test to make transfers fail right away if a device isn't
plugged in. Rather than testing the HPD line directly, we have the
dp_display module tell us when AUX transfers should be enabled so we
can handle cases where HPD is signaled out of band like with Type C.

All the components of YUV420 over DP are added. Therefore, let's mark the
connector property as true for DP connector when the DP type is not eDP
and when there is a CDM block available.
Changes in v3:
- Move setting the connector's ycbcr_420_allowed parameter so
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
checking if VSC SDP is allowed when setting the dp connector's
ycbcr_420_allowed parameter

Adjust the encoder format programming in the case of video mode for DP

- Remove hw_cdm check when getting the fmt_fourcc in
dpu_encoder_phys_vid_enable()
Changes in v2:
- Move timing engine programming to a separate patch from this
one
- Move update_pending_flush_periph() invocation completely to
this patch
- Change the logic of dpu_encoder_get_drm_fmt() so that it only
calls drm_mode_is_420_only() instead of doing additional
unnecessary checks
- Create new functions msm_dp_needs_periph_flush() and it's

if the mode is YUV420 and VSC SDP is enabled before doing a
peripheral flush

DP controller can be setup to operate in either SDP update flush mode or
peripheral flush mode based on the DP controller hardware version.
Starting in DP v1.2, the hardware documents require the use of
peripheral flush mode for SDP packets such as PPS OR VSC SDP packets.
In-line with this guidance, lets program the DP controller to use
peripheral flush mode starting DP v1.2
Changes in v4:
- Clear up that DP_MAINLINK_CTRL_FLUSH_MODE register requires
the use of bits [24:23]
- Modify macros DP_MAINLINK_FLUSH_MODE_UPDATE_SDP and
DP_MAINLINK_FLUSH_MODE_SDP_PERIPH_UPDATE to explicitly set
their values in the bits of DP_MAINLINK_CTRL_FLUSH_MODE_MASK
Changes in v3:
- Clear up that the DP_MAINLINK_FLUSH_MODE_SDE_PERIPH_UPDATE
macro is setting bits [24:23] to a value of 3
Changes in v2:
- Use the original dp_catalog_hw_revision() function to
correctly check the DP HW version

Add support to pack and send the VSC SDP packet for DP. This therefore
allows the transmision of format information to the sinks which is
needed for YUV420 support over DP.
Changes in v5:
- Slightly modify use of drm_dp_vsc_sdp_pack()
- Remove dp_catalog NULL checks
- Modify dp_utils_pack_sdp_header() to more clearly pack the
header buffer
- Move dp_utils_pack_sdp_header() inside of
dp_catalog_panel_send_vsc_sdp to clearly show the relationship
between the header buffer and the vsc_sdp struct
- Due to the last point, remove the dp_utils_pack_vsc_sdp()
function and only call drm_dp_vsc_sdp_pack() in
dp_panel_setup_vsc_sdp_yuv_420()
Changes in v4:
- Remove struct msm_dp_sdp_with_parity
- Use dp_utils_pack_sdp_header() to pack the SDP header and
parity bytes into a buffer
- Use this buffer when writing the VSC SDP data in
dp_catalog_panel_send_vsc_sdp()
- Write to all of the MMSS_DP_GENERIC0 registers instead of just
the ones with non-zero values
Changes in v3:
- Create a new struct, msm_dp_sdp_with_parity, which holds the
packing information for VSC SDP
- Use drm_dp_vsc_sdp_pack() to pack the data into the new
msm_dp_sdp_with_parity struct instead of specifically packing
for YUV420 format
- Modify dp_catalog_panel_send_vsc_sdp() to send the VSC SDP
data using the new msm_dp_sdp_with_parity struct
Changes in v2:
- Rename GENERIC0_SDPSIZE macro to GENERIC0_SDPSIZE_VALID
- Remove dp_sdp from the dp_catalog struct since this data is
being allocated at the point used
- Create a new function in dp_utils to pack the VSC SDP data
into a buffer
- Create a new function that packs the SDP header bytes into a
buffer. This function is made generic so that it can be
utilized by dp_audio
header bytes into a buffer
- Create a new function in dp_utils that takes the packed buffer
and writes to the DP_GENERIC0_* registers
- Split the dp_catalog_panel_config_vsc_sdp() function into two
to disable/enable sending VSC SDP packets
- Check the DP HW version using the original useage of
dp_catalog_hw_revision() and correct the version checking
logic
- Rename dp_panel_setup_vsc_sdp() to
dp_panel_setup_vsc_sdp_yuv_420() to explicitly state that
currently VSC SDP is only being set up to support YUV420 modes

Parity calculation is necessary for VSC SDP implementation. Therefore
create new files dp_utils.c and dp_utils.h and move the parity

programming in both dp_catalog.c and dp_audio.c
Changes in v3:

This reverts commit e467e0bde8 ("drm/msm/dp: use
drm_bridge_hpd_notify() to report HPD status changes").
The commit changed the way how the MSM DP driver communicates
HPD-related events to the userspace. The mentioned commit made some of
the HPD events being reported earlier. This way userspace starts poking
around. It interacts in a bad way with the dp_bridge_detect and the
driver's state machine, ending up either with the very long delays
during hotplug detection or even inability of the DP driver to report
the display as connected.
A proper fix will involve redesigning of the HPD handling in the MSM DP
driver. It is underway, but it will be intrusive and can not be thought
about as a simple fix for the issue. Thus, revert the offending commit.

All supported platforms use the same clocks configuration. Instead of
parsing names from DT in a pretty complex manner, use the static
configuration. If at some point newer (or older) platforms have
different clock configuration, this clock config can be moved to the
device data.

It makes little sense to split the submodule get and actual DT parsing.
Call dp_parser_parse() directly from dp_parser_get(), so that the parser
data is fully initialised once it is returned to the caller.
