Subject: [RFC PATCH 0/3] Add current load setting for qcom camss csiphy

Currently qcom camss csiphy drivers don’t set regulator’s currents
load properly using Linux regulator framework. This causes every 
regulator’s initial mode set as HPM (high current mode), 
which may have higher power consumption.
To address this issue, add current configuration for CSIPHY.

Wenmeng Liu (3):
  media: dt-bindings: Add regulator current load
  media: qcom: camss: csiphy: Add regulator current load setting
  arm64: dts: qcom: qcs6490-rb3gen2: Add csiphy current support
