From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>
The documentation for spi_master.set_cs() says:
assert or deassert chip select, true to assert
i.e. its "enable" parameter uses assertion-level logic.
This does not match the implementation of spi_set_cs(), which calls spi_master.set_cs() with the wanted logic level of the chip select line, which depends on the polarity of the chip select signal.
Correct the documentation to match the implementation.
Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org> --- v2: Changed documentation instead of implementation
