sh-hspi driver which doesn't need platform data at the time of registration can be registerd on SoC. And, registering these drivers in the SoC code can avoid unwanted device numbering issue.

2013-07-24ARM: shmobile: r8a73a4: Remove ->init_machine() special caseMagnus Damm1-6/+0
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 Horman6-2/+67
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 Damm1-6/+45
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.
