This patch adds a sample DT-based APE6EVM "reference" implementation. The use of platform-specific C-code should be avoided with this configuration as much as possible. Signed-off-by:

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. Reported-by:

Update the EMEV2 SMP code to access the SMU directly instead of relying on help from the legacy clock code. This change moves us one step closer to common clocks. Signed-off-by:

Add clock event support for CMT1 timer channel 0 to the r8a73a4 SoC code. The CMT is used together with a 32KHz clock in this case. Signed-off-by:

Add clock event support for CMT0 timer channel 0 to the r8a7790 SoC code. On most ARM mach-shmobile the CMT is hooked up to a 32KHz clock but on r8a7790 a 31.7KHz clock is instead used. Signed-off-by:

The r8a7790 MSTP bits should be kept sorted in the same way as on other mach-shmobile SoCs. Move the HSCIF and thermal bits to clean up the current state. Signed-off-by:

r8a73a4 SoCs have numerous I2C controllers, of which 9 are compatible with the i2c-sh_mobile.c driver. This patch adds clock definitions for them. Signed-off-by:

The Z2 clock on r8a73a4 is used to clock the 4 Cortex A7 cores on the SoC. Add a definition for this clock to later use it from the arm_big_little CPUFreq driver. Signed-off-by:

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 such a check for the Z-clock on r8a73a4. Signed-off-by:

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. Signed-off-by:

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. This patch adds the waiting part, that was missing until now. Acked-by:

Add a DT reference implementation for the KZM9D board. Only DT devices are used in this case. UART, STI, GPIO and SMP / GIC are all provided by emev2.dtsi. There is still a board specific C file used for enabling legacy SH clocks. This file will be removed after we have moved over to common clocks. Signed-off-by:

This adds DT templates for all MMCIF and SDHI controllers on r8a7790. They are added with status="disabled". To use them platform-specific DTs have to enable the required ones. Signed-off-by:

Update the EMEV2 struct map_desc to exclude the SMU and also include the ->map_io() callback in the DT version of EMEV2 board support. The EMEV2 SMP code can these days perform ioremap() early on without the SMU information in the io_desc[]. To correctly support SMP in case of DT-only board support then the ->map_io() callback is needed. Signed-off-by:

This patch removes r8a7778_init_irq(), since no-one is using it. And now, there is no reason to have r8a7778_init_irq_common(). r8a7778_init_irq_dt() includes it. Signed-off-by:
