R. A. Prado [ Upstream commit 7112e0b0a58be8575547eba6596c42710922674f ] The configuration for mt8192 was incorrectly using the output formats from mt8173. Since the output formats for mt8192 are instead the same ones as for mt8183, which require two bus samples per pixel, the pixelclock and DDR edge setting were misconfigured. This made external displays unable to show the image. Fix the issue by correcting the output format for mt8192 to be the same as for mt8183, fixing the usage of external displays for mt8192.
