power: msm8937: Support power profiles
Author: BeYkeRYkt <beykerykt@gmail.com> Date: Sun Dec 23 22:55:35 2018 +0900 power: Add specific powerhal for msm8937 * msm8937 is on the same CAF line along with msm8953 and msm8996 and also supports the MPCTL_V3 commands, in contrast to msm8952. Separate it from msm8952. Change-Id: I58b0d7563cd3896ee4484ed0e0f38a6ef7eb01b2 Author: BeYkeRYkt <beykerykt@gmail.com> Date: Sun Dec 23 23:21:50 2018 +0900 power: msm8937: Update power profile settings * msm8937 supports the MPCTL_V3 commands. Change-Id: Ibeaaf3d4577a8378f1d9a495b87ac58f75b1da73 Author: dianlujitao <dianlujitao@lineageos.org> Date: Sat Feb 23 20:24:57 2019 +0800 power: Pass NULL parameter in powerHint if data is zero * This restores the behavior in AOSP and CAF power HAL to avoid confusion.
