drm/amd/display: Check engine is not NULL before acquiring

2020-02-11T20:07:03+00:00

[Why] Engine can be NULL in some cases, so we must not acquire it. [How] Check for NULL engine before acquiring. Signed-off-by: Aric Cyr Reviewed-by: Harry Wentland Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: init hw i2c speed

2020-01-22T21:55:28+00:00

[Why] Driver didn't init hw i2c speed cause hdcp hw cannot send command, because the default value of speed register is 0x2. [How] Restore the default speed when release i2c engine Signed-off-by: Lewis Huang Reviewed-by: Tony Cheng Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: Refine i2c frequency calculating sequence

2020-01-22T21:55:27+00:00

[Why] In HG mode, vbios didn't call DispController_Init to program NV1x XTAL_REF_DIV value when ASIC_INIT, but driver read XTAL_REF_DIV to calculate i2c reference frequency. it cause i2c frequency change from 100kHz to 200kHz. [How] remove get_speed function and calculate reference frequency at set_speed functiton. Signed-off-by: Lewis Huang Reviewed-by: Jun Lei Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: remove psr state condition when psr exit case

2020-01-16T19:15:56+00:00

[Why] DMCU need to wait a vblank to handle psr enter command. When psr exit coming before vblank, the psr exit command will be skip because current psr state is disable.

drm/amd/display: Increase the number of retries after AUX DEFER

2019-12-05T21:32:45+00:00

[Why] When a timeout occurs after a DEFER, some devices require more retries than in the case of a regular timeout. [How] In a timeout occurrence, check whether a DEFER has occurred before the timeout and retry MAX_DEFER_RETRIES retries times instead of MAX_TIMEOUT_RETRIES.

drm/amd/display: add separate of private hwss functions

2019-12-05T21:26:46+00:00

[Why] Some function pointers in the hwss function pointer table are meant to be hw sequencer entry points to be called from dc. However some of those function pointers are not meant to be entry points, but instead used as a code reuse/inheritance tool called directly by other hwss functions, not by dc. Therefore, we want a more clear separation of which functions we determine to be interface functions vs the functions we use within hwss. [How] DC interface functions will be stored in: struct hw_sequencer_funcs Functions used within HWSS will be stored in: struct hwseq_private_funcs Signed-off-by: Anthony Koo Reviewed-by: Tony Cheng Acked-by: Leo Li Signed-off-by: Alex Deucher
