Hello Jeevan,
Small nitpick, can this be igt_get_i915_edp_lobf_status, since we are not reading other info. Also do we need to use aux wake alpm / aux less alpm status or that doesn't matter? Animesh any thoughts from you here? Thanks and Regards Kunal JoshiAdded helper functions to check LOBF status to check weather it is enabled or disabled.
