2013-08-06ARM: shmobile: marzen: Use DT for GICKuninori Morimoto
Current Marzen is using DT booting, and r8a7779.dtsi already has GIC settings. So, we can remove the C version of the GIC setup code, instead rely on GIC information provided by DT.

2013-08-05ARM: shmobile: Mount root file systems in r/w mode for all DT platformsLaurent Pinchart
The shmobile DT files available in the kernel are reference implementations intended to be used as sample code, as well as for development. As such, it makes sense to mount the root file system in read/write mode by default.

2013-07-30ARM: shmobile: r8a7779: cleanup registration of usb phyKuninori Morimoto
usb phy driver which needs platform data at the time of registration is used from Marzen only. Now, ARM/shmobile aims to support DT, and the C code base board support will be removed if DT support is completed. Current driver registration method which needs platform data and which is not shared complicates codes. This means legacy C code cleanup after DT supporting will be more complicated This patch registers it on board code as cleanup C code Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2013-07-24ARM: shmobile: r8a73a4: Remove ->init_machine() special caseMagnus Damm
No need to special case r8a73a4 ->init_machine(), so get rid of undesired cpufreq platform device from the generic long term r8a73a4 DT support code. For short term support on APE6EVM the DT reference implementation already adds a "cpufreq-cpu0" platform device so that can be used for development. Regarding more long term cpufreq support, perhaps it makes sense to adjust the cpufreq driver to check for DT information directly instead of using a platform device for software configuration and DT for hardware parameters.

2013-07-17ARM: shmobile: lager: Add DT referenceSimon Horman
This is sufficient to allow boot of the Lager board with a console without boards-lager.c compiled into the kernel. This is an example of a minimal but still useful initialisation of the board using DT as much as possible. As such it is the same as the boot of Lager that can be achieved without a board file. The intention of adding this file is to facilitate further work to allow board specific devices to be initialised via DT.

2013-07-17ARM: shmobile: Setup r8a7790 arch timer based on MD pinsMagnus Damm
Update the r8a7790 arch timer setup code to configure the frequency dynamically at boot time. This means that the arch timer driver will be able to detect a timer frequency that has been calculated based on the MD pins instead of a fixed and potentially incorrect 13 MHz. With this patch applied the Linux kernel will correctly support the r8a7790 Lager board that uses a 20 Mhz EXTAL. The arch timer will operate on 10 MHz and the Linux arch timer driver will be correctly configured to use 10 MHz. Without this patch the 20 MHz EXTAL will be used to drive the arch timer at 10 MHz, but the Linux arch timer driver will believe it is counting at 13 Mhz.
