Subject: [PATCH 5.1 313/371] ARM: dts: gemini: Set DIR-685 SPI CS as active low
From: Linus Walleij <linus.walleij@...aro.org>
commit f90b8fda3a9d72a9422ea80ae95843697f94ea4a upstream.
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.
