We want to connect two devices on the SPI bus of the mangOH yellow, but documentation says there is only one chip select pin available and thus only one spidev1.0 is found in /dev directory.
However Qualcomm docs and linux spi driver say that SPI should support four chip selects.
Even more - Linux device tree documentation states that using “cs-gpios” should be possible to set virtually any gpio as an SPI chip select.
So the question is - how to enable additional SPI chip select (preferably hw or at least gpio) and add another /dev/spidev1.1 associated with the chip select in mangOH yellow, so we can connect another SPI device?
I already wasted 3 days trying lots of DTS configuration without success.
