| Subject | [PATCH v2 1/3] ARM: dts: imx6qdl-apalis: Do not rely on DDC I2C bus bitbang for HDMI |
| Message-ID | <siZjs-1jp-11@gated-at.bofh.it> |
Remove the use of DDC I2C bus bitbang to support reading of EDID
and rely on support from internal HDMI I2C master controller instead.
As a result remove the device tree property ddc-i2c-bus.
