2013-07-25ARM: shmobile: No need to use INTC demux on r8a7740Magnus Damm1-1/+0
Now when the r8a7740 code has been converted to make use of GIC instead of INTC for root interrupt controller it is possible to exclude the low level INTC demux function shmobile_handle_irq_intc from linking.

The functions in pm-rmobile.c are only used on sh7372 and r8a7740, so adjust the Makefile to only link in that file in case those SoCs are selected. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
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: 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.

2013-07-17ARM: shmobile: r8a73a4: safeguard against wrong clk_set_rate() usesGuennadi Liakhovetski1-1/+13
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.

2013-07-17ARM: shmobile: r8a73a4: wait for completion when kicking the clockGuennadi Liakhovetski1-6/+16
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[].
