From bd6857a0c630207484a03ddc470fab34b23f80bb Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 21 Jan 2014 16:10:07 +0100 Subject: [PATCH] spi: Correct set_cs() documentation 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.
