Dear NXP ,
I want to set HDMI I2C (HDMI_DDC_SCL/HDMI_DDC_SDA ) from 100Khz to 400Khz in imx8mplus platform.
I modify as follows:
imx8mp.dtsi:
hdmiphy: hdmiphy@32fdff00 {
compatible = "fsl,samsung-hdmi-phy";
reg = <0x32fdff00 0x400>;
#clock-cells = <1>;
clocks = <&hdmi_blk_ctrl IMX8MP_CLK_HDMI_BLK_CTRL_TX_PHY_APB_CLK>,
<&hdmi_blk_ctrl IMX8MP_CLK_HDMI_BLK_CTRL_GLOBAL_XTAL24M_CLK>;
clock-names = "apb", "ref";
clock-output-names = "hdmi_phy";
#phy-cells = <0>;
resets = <&hdmi_blk_ctrl IMX8MP_HDMI_BLK_CTRL_HDMI_PHY_RESET>;
status = "disabled";
};
Test result : It still is 100KHZ.
Please tell me how to set it (HDMI i2c) to 400KHZ
