Embedded DisplayPort* (eDP*/MIPI*) Backlight Control Signals

Embedded DisplayPort* (eDP*/MIPI*) Backlight Control Signals

Name Type Description
eDP_​VDDEN O Primary eDP/MIPI Panel power Enable: Panel power control enable. This signal is used to control the VDC source of the panel logic.
eDP_​BKLTEN O Primary eDP/MIPI Backlight Enable: Panel backlight enable control for eDP/MIPI This signal is used to gate power into the backlight circuitry.
eDP_​BKLTCTL O Primary eDP/MIPI Panel Backlight Brightness control: Panel brightness control for eDP/MIPI. This signal is used as the PWM Clock input signal.
GPP_​A17 / DISP_​MISCC / I2S4_​TXD O Secondary eDP/MIPI Panel power Enable: Panel power control enable. This signal is used to control the VDC source of the panel logic.
GPP_​A21 / DDPC_​CTRLCLK / I2S5_​TXD O Secondary eDP/MIPI Backlight Enable: Panel backlight enable control for eDP/MIPI This signal is used to gate power into the backlight circuitry.
GPP_​A22 / DDPC_​CTRLDATA / I2S5_​RXD O Secondary eDP/MIPI Panel Backlight Brightness control: Panel brightness control for eDP/MIPI. This signal is used as the PWM Clock input signal.
GPP_​E22 / DDPA_​CTRLCLK /DNX_​FORCE_​RELOAD I/O Primary MIPI panel Power enable : Secondary power enable AVEE.
GPP_​E23 / DDPA_​CTRLDATA I/O Primary MIPI panel Power enable : Secondary power enable AVDD.
GPP_​H16 / DDPB_​CTRLCLK / PCIE_​LNK_​DOWN I/O Secondary MIPI panel Power enable : Secondary power enable AVEE.
GPP_​H17 / DDPB_​CTRLDATA I/O Secondary MIPI panel Power enable : Secondary power enable AVDD.
Note: eDP_​VDDEN, eDP_​BKLTEN, eDP_​BKLTCTL, DISP_​MISCC, DDPC_​CTRLCLK, DDPC_​CTRLDATA can be left as no connect if eDP*/MIPI* is not used.
