   4 Subject: [PATCH] phy: rockchip: naneng-combphy: Use
   5  syscon_regmap_lookup_by_phandle
   6
   7 Change to use syscon_regmap_lookup_by_phandle() helper instead of
   8 finding the syscon udevice and making a call to syscon_get_regmap().
   9
  10 No runtime change is expected with this simplication.
