2013-07-30ARM: shmobile: ape6evm-reference: switch PFC to DTGuennadi Liakhovetski
PFC pinctrl configuration can now be performed via DT. Update ape6evm-reference to use this. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-07-26ARM: shmobile: sh73a0: Rely on DT for SMP CPU infoMagnus Damm
Remove sh73a0 specific ->smp_init_cpus() callback and instead of relying on shmobile_smp_init_cpus() simply use DT for CPU core information. This assumes that DT_MACHINE_START is used which is the case when AG5EVM and Kota2 are removed.

2013-07-26ARM: shmobile: bockw: add DT referenceKuninori Morimoto
This patch adds a sample DT-based Bock-W "reference" implementation. The use of platform-specific C-code should be avoided with this configuration as much as possible.

2013-07-17ARM: shmobile: Minor update for the Lager DT reference codeMagnus Damm

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.

2013-07-17ARM: shmobile: r8a73a4: safeguard against wrong clk_set_rate() usesGuennadi Liakhovetski
clk_set_rate() should only be called with exact rates, returned by clk_round_rate(). However, it is still good to verify, that the value, passed to clock's .set_rate() method is at least valid.

This patch adds support for the Z-clock on r8a73a4 SoCs, which is driving the Cortex A15 core, and a "cpufreq-cpu0" platform device. Adding an "operating-points" property to the CPU0 DT node and a regulator, this patch allows platforms to use the generic cpufreq-cpu0 driver to use SoC's DVFS capabilities.

To reconfigure clocks, controlled by FRQCRA and FRQCRB, a kick bit has to be set and to make sure the setting has taken effect, it has to be read back repeatedly until it is cleared by the hardware.

The EMEV2 SMP code can these days perform ioremap() early on without the SMU information in the io_desc[].
