[Why] The DISPCLK value was previously requested to be 15% higher for all ASICs that went through the dce110 bandwidth code path. As part of a refactoring of dce_clocks and the dce110 set bandwidth codepath this was removed for power saving considerations. That change caused display corruption under certain hardware configurations with Vega10. [How] The 15% DISPCLK increase is brought back but only on dce110 for now. This is should be a temporary workaround until the root cause is sorted out for why this occurs on Vega (or other ASICs, if reported). Tested-by:

[WHY] Previously night light forced a full update by applying a transfer function update regardless of if it was changed. This logic was removed, Now gamma surface updates are only applied when there is also a plane info update, this does not work in cases such as using the night light slider. [HOW] When moving the night light slider we will perform a full update if the gamma has changed and there is a surface, even when the surface has not changed. Also get stream updates in setgamma prior to update planes and stream. Signed-off-by:

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:

Currently the driver overwrites the surface depth provided by the fb helper to give an invalid bpp/surface depth combination. This has been exposed by commit 70109354 ("drm: Reject unknown legacy bpp and depth for drm_mode_addfb ioctl"), which now causes the driver to fail to probe. Fix by not overwriting the surface depth.

The official way to stop the display is to clear the display enable (DEN) bit in the DSYSR register, but that operates at a group level and affects the two channels in the group. To disable channels selectively, the driver uses TV sync mode that stops display operation on the channel and turns output signals into inputs. While TV sync mode is available in all DU models currently supported, the D3 and E3 DUs don't support it. We will thus need to find an alternative way to turn channels off. In the meantime, condition the switch to TV sync mode to the availability of the feature, to avoid writing an invalid value to the DSYSR register. When the feature is unavailable the display output will turn blank as all planes are disabled when stopping the CRTC. Signed-off-by:

DSYSR is a DU channel register that also contains group fields. It is thus written to by both the group and CRTC code, using read-update-write sequences. As the register isn't initialized explicitly at startup time, this can lead to invalid or otherwise unexpected values being written to some of the fields if they have been modified by the firmware or just not reset properly. To fix this we can write a fully known value to the DSYSR register when turning a channel's functional clock on. However, the mix of group and channel fields complicate this. A simpler solution is to cache the register and initialize the cached value to the desired hardware defaults. Signed-off-by:

All Gen3 SoCs supported so far have a fixed association between DPAD0 and DU channels, which led to hardcoding that association when writing the corresponding hardware register. The D3 and E3 will break that mechanism as DPAD0 can be dynamically connected to either DU0 or DU1. Make DPAD0 routing dynamic on Gen3. To ensure a valid hardware configuration when the DU starts without the RGB output enabled, DPAD0 is associated at initialization time to the first DU channel that it can be connected to. This makes no change on Gen2 as all Gen2 SoCs can connected DPAD0 to DU0, which is the current implicit default value. As the DPAD0 source is always 0 when a single source is possible on Gen2, we can also simplify the Gen2 code in the same function to remove a conditional check. Signed-off-by:

On selected SoCs, the DU can use the clock output by the LVDS encoder PLL as its input dot clock. This feature is optional, but on the D3 and E3 SoC it is often the only way to obtain a precise dot clock frequency, as the other available clocks (CPG-generated clock and external clock) usually have fixed rates. Add a DU model information field to describe which DU channels can use the LVDS PLL output clock as their input clock, and configure clock routing accordingly. This feature is available on H2, M2-W, M2-N, D3 and E3 SoCs, with D3 and E3 being the primary targets. It is left disabled in this commit, and will be enabled per-SoC after careful testing. At the hardware level, clock routing is configured at runtime in two steps, first selecting an internal dot clock between the LVDS PLL clock and the external DOTCLKIN clock, and then selecting between the internal dot clock and the CPG-generated clock. The first part requires stopping the whole DU group in order for the change to take effect, thus causing flickering on the screen. For this reason we currently hardcode the clock source to the LVDS PLL clock if available, and allow flicker-free selection of the external DOTCLKIN clock or CPG-generated clock otherwise. A more dynamic clock selection process can be implemented later if the need arises. Signed-off-by:
