2013-07-19ARM: shmobile: armadillo800eva: Add backlight supportLaurent Pinchart1-2/+52

2013-07-17ARM: shmobile: Minor update for the Lager DT reference codeMagnus Damm1-2/+1
Update the Lager DT reference code to get rid of the redundant irqchip header and also make lager_add_standard_devices() static. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Simon Horman <[email protected]>
2013-07-17ARM: shmobile: lager: Add DT referenceSimon Horman8-2/+99
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: ape6evm-reference: add CPUFreq supportGuennadi Liakhovetski2-0/+24
Add CPUFreq support to ape6evm-reference, using a max8973 regulator, that is supplying V_DVFS for the 4 CA15 cores on r8a73a4. Signed-off-by: Guennadi Liakhovetski <[email protected]> Acked-by: Magnus Damm <[email protected]> Signed-off-by: Simon Horman <[email protected]>
2013-07-17ARM: shmobile: ape6evm: add DT referenceGuennadi Liakhovetski8-2/+126
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.

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: Disconnect EMEV2 SMP code from clocksMagnus Damm3-21/+9

2013-07-17ARM: shmobile: Add r8a7790 CMT00 clock eventMagnus Damm2-1/+26
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: Magnus Damm <[email protected]> Signed-off-by: Simon Horman <[email protected]>
2013-07-17ARM: shmobile: Sort r8a7790 MSTP entriesMagnus Damm1-3/+3

2013-07-17ARM: shmobile: r8a73a4: add clocks for I2C controllersGuennadi Liakhovetski1-2/+23

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 such a check for the Z-clock on r8a73a4.

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. This patch adds the waiting part, that was missing until now.

2013-07-17ARM: shmobile: KZM9D DT reference implementationMagnus Damm6-0/+87
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.

2013-07-17ARM: shmobile: EMEV2 map_io updateMagnus Damm1-7/+1
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.
