-To eliminate the resonance noise during system vibrator vibrating, set actuator to specified DAC position(480 on DW9714), then the resonance noise can be obviously improved. To achieve the conbination between vibrator and camera AF actuator,we implemnte: - Actuator separately control during camera power off. - Actuator policy to avoid vibrating disturb normal camera AF. port from (CR),fix berlna wide camera resonance noise issue. -Port from (CR): cam/actuator: Add CCI access lock to avoid conflicts. Usually actuator initial setting will execute power down reset(PD), actuator can't respond CCI access for a while after PD. Add lock to avoid access actuator while PD operation. -Port from (CR): cam/actuator: Create separate work queue for park lens. Park lens may cost more than 100ms for different camera modules, create seperate work queue for actuator to avoid park lens operation block system_wq too long. -Port from (CR): cam/actautor: Optimizing park lens for vibrating. Move lens to noise reduction postion after camera exited. -Port from (CR): cam/actuator: Avoid error releasing CCI/regulator. Avoid unbalanced aquire/release of CCI/regulator when actuator init failed. Due to when CCI init for vibrator failed, regulators had been released. -For new baseline sm8350,compile this standalone actuator diver into camera.ko Change-Id: If77d10badfb4147c467ebae238f4e6af317d466f Signed-off-by: wangshuo18 <wangshuo18@lenovo.com> Reviewed-on: https://gerrit.mot.com/1906964 SLTApproved: Slta Waiver SME-Granted: SME Approvals Granted Tested-by: Jira Key Reviewed-by: Dawei Wang <wangdw10@motorola.com> Reviewed-by: Darong Huang <huangdra@motorola.com> Reviewed-by: Long Cheng <chengl1@motorola.com> Reviewed-by: Xu Ji <jixu@motorola.com> Reviewed-by: Jian Zhang <zhangjo@motorola.com> Reviewed-by: Zhuoran Xu <xuzr3@motorola.com> Reviewed-by: Bolei Shang <shangbl1@lenovo.com> Reviewed-by: Zhenxin Xi <xizx@motorola.com> Submit-Approved: Jira Key |
