2018-09-26drm/amd/display: remove redundant null pointer check before kfreezhong jiang1-6/+2

2018-09-26drm/amd/display: Raise dispclk value for dce120 by 15%Nicholas Kazlauskas1-0/+3
[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).

2018-09-26drm/amd/display: fix gamma not being appliedSivapiriyanKumarasamy1-5/+14
[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.

2018-08-27drm/amd/display: Flatten unnecessary i2c functionsDavid Francis1-77/+34
[Why] The dce_i2c_hw code contained four funtcions that were only called in one place and did not have a clearly delineated purpose. [How] Inline these functions, keeping the same functionality. This is not a functional change. The functions disable_i2c_hw_engine and release_engine_dce_hw were pulled into their respective callers. The most interesting part of this change is the acquire functions. dce_i2c_hw_engine_acquire_engine was pulled into dce_i2c_engine_acquire_hw, and dce_i2c_engine_acquire_hw was pulled into acquire_i2c_hw_engine. Some notes to show that this change is not functional: -Failure conditions in any function resulted in a cascade of calls that ended in a 'return NULL'. Those are replaced with a direct 'return NULL'. -The variable result is the one from dce_i2c_hw_engine_acquire_engine. The boolean result used as part of return logic was removed. -As the second half of dce_i2c_hw_engine_acquire_engine is only executed if that function is returning true and therefore exiting the do-while loop in dce_i2c_engine_acquire_hw, those lines were moved outside of the loop.
