I'm using the 4.14.98 GA BSP where I need to use native chip-select (i.e. dedicated SPI chip-select pin instead of GPIO chip-select) for one of our device.
I have gone through the "spi-fsl-lpspi.c" file where they include "<linux/spi/spi_bitbang.h>" but, not specifically used anything directly from the "spi_bitbang" (as far as I understand).
However, the driver still using the "cs-gpios" for chip-select in the probe function.
Hence, I would like to know whether the 4.14.98 GA BSP's spi-fsl-lpspi.c supports native chip-select? I do not have any dedicated GPIO pin for the chip-select and need to use the SPI native chip-select pin for the same.
Could anyone please confirm that, the driver is capable to handle the native chip-select pin instead of a GPIO chip-select pin?
Looking forward to your reply.
Thank you in advance,
