4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Zhang <ma...@nvidia.com>
commit 0ab66b3c326ef8f77dae9f528118966365757c0c upstream.
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.
