SPI GPIO chipselect lines not working

I’ve been attempting to add additional chipselect lines to the SPI on the AGX’s 40-pin header. I’ve added an entry for the cs-gpios field in the device tree for the SPI controller as per the documentation in the linux device tree documentation and accordance with this forum post: TX2 R28.2 SPI CS-GPIO issue

Are there any known issues with using cs-gpios with the AGX? Is there any special configuration required for the GPIOs in order to have them used by the SPI controller?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Could you trace the …/kernel/kernel-4.9/drivers/spi/spi-gpio.c to confirm the configure.

Thanks for your reply. I’ll report back tomorrow with my findings.
