iMX8M mini + PCA9450A + SN65DSI83

[giacomobiancala]

Hi,

On a custom board based on iMX8M mini, I am using PMIC PCA9450A and SN65DSI83 for MIPI-DSI to LVDS conversion.

Is it possible to use the same I2C1 (NVCC_I2C = 1,8V) for these 2 devices?

Do you think it could be a problem to add PCA9450 and SN65DSI83 to kernel?

Thanks,

Giacomo

seems it is possible, as example of usage several devices on one i2c port one can look at

attached  i.MX6Q Sabre AI board schematic p.3 and linux documentation supporting that board on

i.MX Software and Development Tools | NXP

Thank you,

Do you know if it is available a patch to add PCA9450A to kernel? This device is quite new.
