Hello we have custom rk3399 based board which runs debian image that we compiled with the help of this resource : https://wiki.radxa.com/Rockpi4/dev/Debian.
We are trying to make work the IMX219 sensor module right now. In order to do that we also set flag to okay for mipi_rx0, and i2c4 which is used for sensor in dtsi. After Adding few logs in IMX219 sensor driver we found that it gets probed with no any errors however after probing of sensor is done Kernel tries to load the Driver for MIPI DPhy RX0 which fails with Following error :

` rockchip-sy-mipi-dphy ff770000.syscon:mipi-dphy-rx0: invalid resource `

The probe function returns with 0 even after this error but when i try to list video devices I can find the sensor. and i suspect this error could be the reason for that but i have no idea about what might be causing this.

It would be great if someone can point out whats could be the problem.
Thanks.

As you can see in the image when I try to flash the image to my board Dram init is failing. I am thinking this is because we didn't swapped the dram pin in board but Allwinner reference schematics did it so we have to modify than in kernel driver/dts file to assign pin number of DDR3L ram accordingly. Any help will be beneficial.

We designed a board based on V833 processor. According to Schematic provided by Allwinner the Address and Data pins are swapped in DDR3 RAM. But we didn't swapped the pins in our board. Now We are trying to build the Linux image for board but as the pins of DDR3 ram is not swapped the processor didn't boot. So how to define the pins for DDR ram in kernel. Any help will be appreciated.
