[why] Prevent clock source sharing between HDMI and DP connectors. DP shouldn't be sharing its ref clock with phy clock, which caused an issue of older ASICS booting up with multiple diplays plugged in. [how] Add an extra check that would prevent HDMI and DP sharing clk. Signed-off-by:

[Why] The calculated values for actual disp_clk_khz were ignored when notifying pplib of the new display requirements. In order to honor DFS bypass clocks from the hardware, the calculated value should be used. [How] The return value for set_dispclk is now assigned back into new_clocks and correctly carried through into dccg->clks.phyclk_khz. When notifying pplib of new display requirements dccg->clks.phyclk_khz is used instead of dce.dispclk_khz. The value of dce.dispclk_khz was never explicitly set to anything before. A 15% higher display clock value than calculated is no longer requested for dce110 since it now makes use of the calculated value. Since dce112 makes use of dce110's set_bandwidth but not its update_clocks it needs to have the value correctly carried through. Signed-off-by:

[Why] If there is no program explicitly setting the backlight brightness (for example, during a minimal install of linux), the hardware defaults to maximum brightness but the backlight_device defaults to 0 value.

[Why] VGA sometimes has trouble retrieving the EDID on very long cables, KVM switches, or old displays. [How] Only require EDID read for HDMI and DVI and exempt other types (DP, VGA). We currently don't support VGA but if anyone adds support in the future this might get overlooked. Signed-off-by:

[Why] Some boards seem to have a problem where HPD is high on HDMI even though no display is connected. We don't want to report these as connected. DP spec still requires us to report DP displays as connected when HPD is high but we can't read the EDID in order to go to fail-safe mode.

idx can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:408 amdgpu_set_pp_force_state() warn: potential spectre issue 'data.states' Fix this by sanitizing idx before using it to index data.states Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. Signed-off-by:
