[why] As a fail-safe, in case 'set FEC_READY' DPCD write fails, a HW shadow register should be cleared and the internal FEC stat should be set to 'not ready'. This is to make sure HW settings will be consistent with FEC_READY state on the RX. Signed-off-by:

[Why&How] 1. Stack usage is pretty high as fixed31_32 struct is 8 bytes and we have functions with >30 vars on the stack. 2. Optimize gamma calculation by reducing number of calls to dc_fixpt_pow Our X points are divided into 32 regions wth 16 pts each. Each region is 2x the previous, meaning x[i] = 2*x[i-16] for i>=16. Using (2x)^gamma = 2^gamma * x^gamma, we can recursively compute powers of gamma, we just need first 16 pts to start it up. dc_fixpt_pow() is expensive, it computes x^y by doing exp(y*logx) Exp is done by Taylor series approximation, and log by Newton-like approximation that also uses exp internally. In short, it's significantly heavier than run-of-the-mill addition/subtraction/multiply. Signed-off-by:

[Why] Seamless boot optimization removed proper front end power off sequence. In driver disable enable case, this causes driver to power gate hubp and dpp while there is still memory fetching going on, this can cause invalid memory requests to be generated which will hang data fabric.

[why] Right now we FEC_READY is set only before the final link training, i.e. at mode set time. This means FEC_READY won't be set when doing link training as a response to HPD. It also fails UCD400 FEC test in DP compliance. [how] Move FEC_READY setup to link training. Signed-off-by:

[Why] Some display's hsync width is lower than the minimum dcn20 is set to support right now. This will cause optc1_validate_timing to fail which eventually will result in wrong set mode. This was set to 8 as per HW team's request for no valid reason. [How] Changing min_h_sync_width to 4 will let us validate timing for preffered mode and light up the headset. This change was made to Vega 10 before for a similar issue. Signed-off-by:

[Why] On some platforms, the encoder id 3 is not populated. So the encoders are not stored in right order as index (id: 0, 1, 2, 4, 5) at pool. This would cause encoders id 4 & id 5 to fail when finding corresponding audio device, defaulting to the first available audio device. As result, we cannot stream audio into two DP ports with encoders id 4 & id 5. [How] It need to create enough audio device objects (0 - 5) to perform matching. Then use encoder engine id to find matched audio device. Signed-off-by:

[why] When the system is going into suspend, set_backlight gets called after the eDP got blanked. Since smooth brightness is enabled, the driver will make a call into the DMCU to ramp the brightness. The DMCU would try to enable ABM to do so. But since the display is blanked, this ends up causing ABM1_ACE_DBUF_REG_UPDATE_PENDING to get stuck at 1, which results in a dead lock in the DMCU firmware.

[Why] Fixes issue when we have a display connected using a passive dongle and then emulate over it using a DP connection at 1 x 1.62 Ghz. System hangs because register bus returns back 0xFFFFFFFF for all register reads after setting register DIG_BE_CNTL in dcn10_link_encoder_connect_dig_be_to_fe(). Hang occurs later when trying to do a register read. [How] At the start of the emulation, dc_link_set_preferred_link_settings() and dp_retrain_link_dp_test() is called, even though it is connected using a passive dongle. Add an extra condition in dp_retrain_link_dp_test() to check for link->dongle_max_pix_clk > 0. This is the only way we know if the connection is using passive dongle so we don't retrain DP.
