From mboxrd@z Thu Jan 1 00:00:00 1970 From: hechtb@gmail.com (Bastian Hecht) Date: Mon, 4 Mar 2013 17:20:54 +0100 Subject: [PATCH v4 3/3] ARM: mach-shmobile: r8a7740: Setup the serial devices using DT In-Reply-To: <1362414054-23092-1-git-send-email-hechtb+renesas@gmail.com> References: <1362414054-23092-1-git-send-email-hechtb+renesas@gmail.com> Message-ID: <1362414054-23092-3-git-send-email-hechtb+renesas@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org We can now use the Device Tree for bringing up our serial devices on the SoC r8a7740. We remove the power domain association. We will move the info into the DT setup as soon as we have support for it. For now this is fine as we use the power domain governor "pm_domain_always_on_gov" for A3SP. Signed-off-by: Bastian Hecht --- v4: We don't move the DT into the r8a7740-armadillo800eva-reference.dts, but r8a7740.dtsi as the serial device setups are not dependent on any board confguration.
