imx6dl HDMI Read EDID time out

[frankweng]

OS:Android4.4.2/kernel3.0.15

定義:EIM_D16__HDMI_TX_DDC_SDA/EIM_D16__HDMI_TX_DDC_SDA作位HDMI SDA/SCL pin

HDMI 使用hdmi_edid_i2c_read funtion  Read EDID-->"mxc_hdmi mxc_hdmi: HDMI EDID i2c operation time out!!"

量測SDA/SCL pin ，並沒有任何訊號波形，因此讓系統認定HDMI 不存在

相同的硬體使用Android6/kernel4.1.15 是正常，也量測的到HDMI I2C 訊號。

請問是否有相關patch檔修改此狀況，麻煩協助，謝謝

Hello Frank,

The 3.0.35 is not supported anymore, but the MX6DLSabreboard is normal that Signal measurement be I2c, you do not need I2C bus for HDMI if HDMI driver has EDID information statically.
