Subject: [PATCH 1/2] regulator: max77620: Initialize values for DT properties
Date: Thu, 10 Jan 2019 12:11:16 +0800 [thread overview]
Message-ID: <20190110041117.8216-1-markz@nvidia.com> (raw)
If regulator DT node doesn't exist, its of_parse_cb callback
function isn't called. Then all values for DT properties are
filled with zero. This leads to wrong register update for
FPS and POK settings.
