[PATCH v1] drm/bridge: it6505: update usleep_range for RC circuit charge time
From: kuro
Date: Mon Jun 03 2024 - 22:34:54 EST
From: Kuro Chung <kuro.chung@xxxxxxxxxx>
The spec of timing between IVDD/OVDD and SYSRTEN is 10ms, but SYSRSTN RC
circuit need at least 25ms for rising time, update for match spec
