From mboxrd@z Thu Jan 1 00:00:00 1970 From: maxime.ripard@free-electrons.com (Maxime Ripard) Date: Tue, 4 Mar 2014 17:28:39 +0100 Subject: [PATCH v3 3/5] ARM: sun6i: Enable the I2C controllers In-Reply-To: <1393950521-4173-1-git-send-email-maxime.ripard@free-electrons.com> References: <1393950521-4173-1-git-send-email-maxime.ripard@free-electrons.com> Message-ID: <1393950521-4173-4-git-send-email-maxime.ripard@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The A31 has 4 I2C controllers that are the same than the one in the other Allwinner SoCs, except for the fact that they are asserted in reset by the reset unit. Add these i2c controllers to the DTSI.
