arm64: dts: turing-rk1: Fix reading EDID information #133

Closed Joshua-Riek closed 8 months ago

Joshua-Riek commented 8 months ago

Hello! This PR will fix reading EDID information on the Turing RK1.

There has been a problem reading data from I2C on this device, and I finally found that adjusting the hold time and rxfilter will fix the problem and allow for successful I2C transfers. The implemented fix will not impact any boards unless they add the device tree property ddc-i2c-rxfilter.

Thanks!
