Hello, I'm using a TC9595 bridge device on a Renesas RZ/G2L custom board that streams video from DSI to DisplayPort. The device is supported by the TC358767 driver. The problem I'm facing is, that the device cannot read the DPCD data from the monitor in "tc_get_display_props()" [1]. Any I2C accesses via AUX channel performed by the chip does fail with a timeout. If I ignore that error and go ahead in that function with default values, the I2C accesses start to work various accesses later. Any idea what could cause that weird behavior? Either the monitor does wake-up for some reason and responds to the accesses or the chip performs the accesses differently.
