f2d51b20d7 drm/amd/display: Fix potential integer overflow
Fix potential integer overflow by casting actual_calculated_clock_100hz
to u64, in order to give the compiler complete information about the
proper arithmetic to use.

Notice that such variable is used in a context that expects
an expression of type u64 (64 bits, unsigned) and the following
expression is currently being evaluated using 32-bit arithmetic:

actual_calculated_clock_100hz * post_divider

148816f93f drm/amd/display: Initialize dmub_rb_cmd unions to 0
[Why]
Since dmub_rb_cmds are not initialized to 0,
the header is filled with invalid data.
This is causing issues on the fw side.

[How]
Initialize dmub_rb_cmd unions to 0.

efa18405ba drm/amd/display: Fix HDMI deep color output for DCE 6-11.
This fixes corrupted display output in HDMI deep color
10/12 bpc mode at least as observed on AMD Mullins, DCE-8.3.

It will hopefully also provide fixes for other DCE's up to
DCE-11, assuming those will need similar fixes, but i could
not test that for HDMI due to lack of suitable hw, so viewer
discretion is advised.

dce110_stream_encoder_hdmi_set_stream_attribute() is used for
HDMI setup on all DCE's and is missing color_depth assignment.

dce110_program_pix_clk() is used for pixel clock setup on HDMI
for DCE 6-11, and is missing color_depth assignment.

Additionally some of the underlying Atombios specific encoder
and pixelclock setup functions are missing code which is in
the classic amdgpu kms modesetting path and the in the radeon
kms driver for DCE6/DCE8.

encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
and radeon kms classic drivers. Added here, but untested due to
lack of suitable test hw.

encoder_control_digx_v4() - Added missing setup code.
Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
output at 10 bpc and 12 bpc.

Note that encoder_control_digx_v5() has proper setup code in place
and is used, e.g., by DCE-11.2, but this code wasn't used for deep
color setup due to the missing cntl.color_depth setup in the calling
function for HDMI.

set_pixel_clock_v5() - Missing setup code wrt. classic amdgpu/radeon
kms. Added here, but untested due to lack of hw.

set_pixel_clock_v6() - Missing setup code added. Successfully tested
on AMD mullins DCE-8.3. This fixes corrupted display output at HDMI
deep color output with 10 bpc or 12 bpc.

1916866dfa drm/amd/display: Fix 10/12 bpc setup in DCE output bit depth reduction.
In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
and COLOR_DEPTH_121212 cases directly contradict the code comment which
explains how this should work, whereas the COLOR_DEPTH_888 case
is consistent with the code comments. Comment says the bitmask should
be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
the implementation contradicts that: 10 bit case sets a mask for 12 bpc
clamping, whereas 12 bit case sets a mask for 14 bpc clamping.

Note that during my limited testing on DCE-8.3 (HDMI deep color)
and DCE-11.2 (DP deep color), this didn't have any obvious ill
effects, neither did fixing it change anything obvious for the
better, so this fix may be inconsequential on DCE, and just
reduce the confusion of innocent bystanders when reading the code
and trying to investigate problems with 10 bpc+ output.

6bdeff12a9 drm/amd/display: Add get_dig_frontend implementation for DCEx
Some old ASICs might not implement/require get_dig_frontend helper; in
this scenario, we can have a NULL pointer exception when we try to call
it inside vbios disable operation. For example, this situation might
happen when using Polaris12 with an eDP panel. This commit avoids this
situation by adding a specific get_dig_frontend implementation for DCEx.

[Why]
Cached backlight is never being updated since panel_cntl specific

Update cached backlight in set_abm_immediate_disable as what we used to
do. Also, update the priority of backlight restore mechanism so that
cached backlight has the highest priority since it is always correct.

[Why]
On some platforms, DMCU is no longer used. In these cases, some DMCU

   use
2. Added a debug option to allow this behaviour to be turned off
3. Set all memory low power debug options to off first, to not

df043738b7 drm/amd/display: Refactor ABM_MASK_SH_LIST_DCN301 naming
[Why]
All DCN3x resources share ABM_MASK_SH_LIST_DCN301 definition.
The naming is misleading since it looks like DCN30 code
depends on next version DCN301, which in fact is vice-versa.

[How]
Refactor the naming to ABM_MASK_SH_LIST_DCN30.

b15cde19c3 drm/amd/display: Add i2c speed arbitration for dc_i2c and hdcp_i2c
[why]
HDCP 1.4 failed on SL8800 SW w/a test driver use.

[how]
Slow down the HW i2c speed when used by HW i2c.
This request: each acquired_i2c_engine setup the i2c speed needed
and sets the I2c engine for HDCP use at release_engine.

This covers SW using HW i2c engine and HDCP using HW i2c engine.
for dmcu using HW i2c engine, needs add similar logic in dmcu fw.

1d5503331b drm/amd/display: fix potential integer overflow when shifting 32 bit variable bl_pwm
The 32 bit unsigned integer bl_pwm is being shifted using 32 bit arithmetic
and then being assigned to a 64 bit unsigned integer.  There is a potential
for a 32 bit overflow so cast bl_pwm to enforce a 64 bit shift operation
to avoid this.
