This is new features and bug fix patch set for DW_HDMI DRM bridge driver
that has verified by NXP i.MX8MPlus.
Two new feature added:
1. Add GPA interface for DW_HDMI Audio.
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.

v2->v3:
1. Drop the patch of Add CEC Suspend/Resume to restore registers.
Because it is not a general feature for other SOCs, their CEC engine are
enabled in suspend for CEC wakeup.
2. More detail comments for patch GCP only for Deep Color.
3. Address coments for patch GPA driver and move enable_audio/disable_audio
from dw_hdmi_phy_ops to dw_hdmi_plat_data.

  drm: bridge: dw_hdmi: add reset function for PHY GEN1
