Fixes for v6.6-rc5 - fix to not reset the PHY everytime we start link training but only do it if link training fails. Without this, the PLL unlocked interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when not busy" spam in the logs since last 2-3 cycles - correct the highest bank bit to match downstream device tree for msm8998 - skip the video mode wait if the timing engine is not enabled. This was introduced after pre_enable flag for DSI video mode panels where we would end up waiting for the video mode done interrupt even before enabling timing engine causing error spam and long bootup times. - check the correct return code of irq_of_parse_and_map() in DSI code - avoid overflow issues in the dpu bandwidth calculation . This was exposed for high resolution displays and a critical fix to avoid atomic_check failure - minor fix to add new lines in DP print messages. - Fix to fail atomic_check() if the resolution exceeds max mdp clk. This leads to underflow otherwise if we try to allow that frame.
