[PATCH v2 8/8] drm: bridge/analogix_dp: expand the delay time for hpd detect

From: Yakir Yang
Date: Fri Aug 07 2015 - 06:56:25 EST


Some edp screen with no hpd signal would need some delay time
to ensure that screen would be ready for work, so we can expand
the delay time in hpd detect function, it works prefectly on my
rk3288 sdk board.
