Subject: [PATCH v2 2/5] fbdev: ssd1307fb: Remove reset-active-low from the DT binding document
Date: Fri, 13 Jan 2017 10:35:46 +0000	[thread overview]
Message-ID: <b68e1b9b735543b9e1511cfeb8e5d9ceec6c7666.1484303628.git.jsarha@ti.com> (raw)
In-Reply-To: <cover.1484303628.git.jsarha-l0cyMroinI0@public.gmane.org>

Remove reset-active-low from the devicetree binding document. The actual
implementation has never been there in the driver code and there is no
reason to add it because the gpiod API supports gpio flags, including
GPIO_ACTIVE_LOW, directly trough its own devicetree binding.
