This is new features and bug fix patch set for DW_HDMI DRM bridge driver that has verified by NXP i.MX8MPlus. Three new feature added: 1. Add GPA interface for DW_HDMI Audio. 2. Add CEC PM functions to restore CEC status when device suspend/resume 3. New API for reset PHY Gen1. Two bugs fixed: 1. Enable overflow workaround for all IP versions later than v1.30a. 2. Clear GCP_Auto bit for 24-bit color depth to pass CTS.
v1->v2: 1. Save CEC interrupt registers in struct dw_hdmi_cec 2. Restore CEC logical address register by cec->addresses. 3. Default enable overflow workaround for all versions later than v1.30a. 4. Add clear_gcp_auto flag to clear gcp_auto bit for all 24-bit color. 5. Remove i.MX8MPlus specific reference.
