General discussion • add a spi master without enabling spidev

Hello,

I am using Raspberry Pi v5.15.92-v7 and would like to add a spi master without enabling spidev. Based on that, I will be able to use my own device driver.

At the beginning, I was referring to the method mentioned at this link https://embetronicx.com/tutorials/linux ... -tutorial/.
I tried the way in the link as below. By the way, putting these two statements in one line, separated by comma, doesn't work for me to create spidev1.0.Although spidev1.0 is created, it still says "chip select 0 is in use".

I suspect that spidev can not be enabled if I would like to use my own device driver on either SPI0 or SPI1.
But how to do that? I couldn't yet find any information that is really relevant.
Anyone can point to the direction to find it out?

Thanks!
Crane
