| From | Sasha Levin <> | Subject | [PATCH AUTOSEL 4.19 138/167] ARM: dts: gemini: Set DIR-685 SPI CS as active low | Date | Tue, 3 Sep 2019 12:24:50 -0400 |

From: Linus Walleij <linus.walleij@linaro.org>
[ Upstream commit f90b8fda3a9d72a9422ea80ae95843697f94ea4a ]
The SPI to the display on the DIR-685 is active low, we were just saved by the SPI library enforcing active low on everything before, so set it as active low to avoid ambiguity.
