[Freedreno] toshiba tc358775 dsi2lvds bridge - backlight and standby to resume not proper

[VINAY SIMHA B N]

hi,

i had implemented the toshiba tc358775 dsi2lvds driver with apq8016 ,
facing two problems. please suggest.

1) display backlight problem - earlier by hard-coding the  panel mode
values in the bridge driver, display backlight was working fine, but
after handling by panel method, display backlight is very low, i had
not added backlight in the panel-simple driver, since it is handled by
led at 7

2) standby to resume - when system goes to standby and comes back by
pressing vol+/vol-/power button sometimes display does not comes
properly

below is the bridge driver and devicetree
