[SpiChannel] Question & suggestion

[BILLyTheLiTTle]

I am trying to have more than 2 devices in SPI0.

I used a GPIO as CS pin.
val pinCS = gpio.provisionDigitalOutputPin(RaspiPin.GPIO_29, "CS")

I am using the MCP23S17GpioProvider class but this class always needs an SpiChannel. I am setting it to SpiChannel.CS0 just to avoid any exceptions.
val provider = MCP23S17GpioProvider(MCP23S17GpioProvider.ADDRESS_0, SpiChannel.CS0)

I successfully done it by setting to low the CS pin before the job and after the job is done to set it to high.
// select the device
pinCS.low()

do the job you have to do

// deselect the device
pinCS.high()

This is not the right way to do it, because I use (for Exception reasons) the CS0 to the MCP23S17GpioProvider contructor. Is there any better way to do it?

Would be a good idea to add another value (SpiChannel.CS) with -1 value just to let the user do whatever he wants?
