Using gpio_cdev the line handler return Error { kind: Ioctl { kind: LineHandle, cause: EBUSY } } when requesting a pin configured as SPI chip select.
In my case, when running a raspberry pi 5:
line 16: "GPIO16" "spi1 CS2" output active-low [used]
ls /dev/spidev*
/dev/spidev0.0 /dev/spidev1.0 /dev/spidev10.0 /dev/spidev1.1 /dev/spidev1.2
Any suggestion or example of how to use chip selects with the new API ?
It appears to run fine in a Raspberry Pi 4.
line 16: "GPIO16" unused output active-high
ls /dev/spidev
spidev0.0 spidev1.0 spidev1.1 spidev1.2
