mmDAGB0_CNTL_MISC2: 0x0071(v2.0) 0x0096(v2.3)
...

Continuing using the same file mmhub v2.0 is not good choice, it will
introduce a lot of checking with ASIC types. And also easy to introduce the
issues that offset not align, this kind of issues are really hard to find. Van
Gogh's mmhub vm invalidation is actually caused by the offset mismatch as well.

So it would like to create a new file rather than stick to re-use orignal mmhub
v2.0 here.

v2: add missed translate_further programming.
v3: sync with latest code
v4: add missing callbacks

95d620adb4 drm/amd/display: HDMI remote sink need mode validation for Linux
[Why]
Currently mode validation is bypassed if remote sink exists. That
leads to mode set issue when a BW bottle neck exists in the link path,
e.g., a DP-to-HDMI converter that only supports HDMI 1.4.

Any invalid mode passed to Linux user space will cause the modeset
failure due to limitation of Linux user space implementation.

[How]
Mode validation is skipped only if in edid override. For real remote
sink, clock limit check should be done for HDMI remote sink.

Have HDMI related remote sink going through mode validation to
elimiate modes which pixel clock exceeds BW limitation.

Rodrigo Siqueira
2f8be0e516 drm/amd/display: Avoid set zero in the requested clk
[Why]
Sometimes CRTCs can be disabled due to display unplugging or temporarily
transition in the userspace; in these circumstances, DCE tries to set
the minimum clock threshold. When we have this situation, the function
bw_calcs is invoked with number_of_displays set to zero, making DCE set
dispclk_khz and sclk_khz to zero. For these reasons, we have seen some
ATOM bios errors that look like:

[drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for more than
5secs aborting
[drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios stuck
executing EA8A (len 761, WS 0, PS 0) @ 0xEABA

[How]
This error happens due to an attempt to optimize the bandwidth using the
sclk, and the dispclk clock set to zero. Technically we handle this in
the function dce112_set_clock, but we are not considering the case that
this value is set to zero. This commit fixes this issue by ensuring that
we never set a minimum value below the minimum clock threshold.

introduced a NULL pointer dereference when booting with
amdgpu.discovery=0, because it removed the call of vega10_reg_base_init()
for that case.

Fix this by calling that funcion if amdgpu_discovery == 0 in addition to
the case that amdgpu_discovery_reg_base_init() failed.

f3d52908f6 drm: bridge: dw-hdmi: Constify dw_hdmi_i2s_ops
The only usage of dw_hdmi_i2s_ops is to assign its address to the ops
field in the hdmi_codec_pdata struct, which is a const pointer. Make it
const to allow the compiler to put it in read-only memory.

4e19d51ca5 drm/gma500: fix double free of gma_connector
clang static analysis reports this problem:

cdv_intel_dp.c:2101:2: warning: Attempt to free released memory
        kfree(gma_connector);
        ^~~~~~~~~~~~~~~~~~~~

In cdv_intel_dp_init() when the call to cdv_intel_edp_panel_vdd_off()
fails, the handler calls cdv_intel_dp_destroy(connector) which does
the first free of gma_connector. So adjust the goto label and skip
the second free.
