Subject: [PATCH v2 3/3] ARM: dts: lpc32xx: disabled ssp0/spi1 & ssp1/spi2 by default
Date: Wed, 20 Apr 2016 09:21:00 -0400	[thread overview]
Message-ID: <1461158460-2946-4-git-send-email-slemieux.tyco@gmail.com> (raw)
In-Reply-To: <1461158460-2946-1-git-send-email-slemieux.tyco-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Sylvain Lemieux <slemieux-1xCVI8+nB4ZBDgjK7y7TUQ@public.gmane.org>

The SSP0/SPI1 and SSP1/SPI2 shared pinout and should be disable by default.

Board specific dts should enable them, as needed.
