2013-06-07ARM: shmobile: bockw: add SDHI0 supportKuninori Morimoto1-0/+29
This patch is directly accessing to PUPR4 register which can control SDHI0 CD/WP pin pull-up setting. It should be replaced in the future. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-06-07ARM: shmobile: marzen: Use INTC External IRQ pin driver for SMSCSimon Horman1-1/+2
Update the marzen board to use the INTC External IRQ pin driver for SMSC. This code was originally posted by Magnus Damm as part of "ARM: shmobile: INTC External IRQ pin driver on r8a7779" but somehow omitted when I applied that patch.

2013-06-07ARM: shmobile: lager: Add GPIO LEDsSimon Horman1-0/+27

2013-06-07ARM: shmobile: bockw: add dummy regulators for SMSCKuninori Morimoto1-0/+11
SMSC driver will try to get regulator if .config had CONFIG_REGULATOR, and, shmobile_defconfig has it. SMSC driver on Bock-W board will be failed if it doens't have dummy regulator settings.

2013-06-07ARM: shmobile: kzm9g: add AS3711 PMIC platform dataGuennadi Liakhovetski1-53/+140
KZM9G uses an AS3711 PMIC to supply power to the CPU and the LCD backlight. The PMIC on the board is pre-programmed to supply correct voltages to the CPU, power supply to the backlight has to be turned on at run-time. The latter is currently performed by a hard-coded I2C command sequence in the board file. This patch removes the backlight hack and instead adds an I2C device to instantiate the AS3711 MFD driver, which will add a regulator device to dynamically adjust CPU voltages and a backlight device.

2013-06-07ARM: shmobile: kzm9d: resigser smsc911x platform device with id -1Simon Horman1-1/+1
As the kzm9d only has one smsc911x device it may be registered as a platform device with id -1. This allows the kzm9d board to access the smsc911x device when CONFIG_REGULATOR (and CONFIG_REGULATOR_FIXED_VOLTAGE) are set. The motivation for which is twofold: using regulators seems to be generally a good thing; it will move the kzm9d defconfig one step closer to being able to be consolidated with other shmobile defconfigs. An alternate but so far untested approach would be to update the definition of dummy_supplies in board-kzm9d.c to use "smsc911x.0" instead of "smsc911x".

2013-06-07ARM: shmobile: ape6evm: MP clock parent become EXTAL2Kuninori Morimoto1-0/+15
The orignal commit 3263e09d287fbaa8a9424b5e69396599a3bbd518 (ARM: shmobile: Initial r8a73a4 SoC support V3) put MP clock parent as EXTAL2, but its code was removed on DIV6 clock support commit.

2013-06-07ARM: shmobile: sh73a0: div4 clocks must check the kick bit before changing rateGuennadi Liakhovetski1-5/+19
According to the datasheet, it is not allowed to change div4 clock rates if an earlier rate change operation is still in progress, as indicated by a set kick bit. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-06-07ARM: shmobile: sh73a0: do not overwrite all div4 clock operationsGuennadi Liakhovetski1-13/+15
An earlier commit "ARM: shmobile: sh73a0: add support for adjusting CPU frequency" intended to replace some clock operations only for the Z-clock, instead it replaced them for all div4 clocks, since all div4 clocks share the same copy of clock operations. Fix this by using a separate clock operations structure for Z-clock. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski+renesas@gmail.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-06-07ARM: shmobile: sh73a0: Always use shmobile_setup_delay()Magnus Damm1-5/+6
Break out the function sh73a0_init_delay() that now gets called both for the C version of the code and the DT -reference boards. This way we handle both cases in the same way. Allows us to boot with TWD only in the kernel configuration for C board code. TWD is not yet enabled in the case of DT -reference - this due to a dependency on CCF.

2013-06-07ARM: shmobile: sh73a0: add CPUFreq supportGuennadi Liakhovetski2-0/+7
This patch enables the use of the generic cpufreq-cpu0 driver on sh73a0. Providing a regulator, a list of OPPs in DT, combined with a virtual cpufreq-cpu0 platform device and a clock, attached to it is everything, the cpufreq-cpu0 driver needs. The first sh73a0 platform, implementing such CPUFreq support is kzm9g-reference.

On SH73A0 the output of PLL0 is supplied to two dividers, feeding clock to the CPU core and SGX. Lower CPU frequencies allow the use of lower supply voltages and thus reduce power consumption.
