2011-07-14ARM / shmobile: Return -EBUSY from A4LC power off if A3RV is activeRafael J. Wysocki
Since the A4LC should only be powered off if the A3RV is off, make the A4LC's power down routine return -EBUSY if A3RV is not off to indicate to the core that it doesn't want to power off the domain in that case. This will cause the core to regard A4LC as active, so the pm_genpd_poweron() in pd_power_down_a3rv() is not necessary any more. Signed-off-by: Rafael J.

2011-07-10ARM: mach-shmobile: sh7372 A3RV requires A4LCMagnus Damm
Add a power domain workaround for the VPU and A3RV on sh7372. The sh7372 data sheet mentions that the VPU is located in the A3RV power domain. The A3RV power domain is not related to A4LC in any way, but testing shows that unless A3RV _and_ A4LC are powered on the VPU test program will bomb out. This issue may be caused by a more or less undocumented dependency on the MERAM block that happens to be located in A4LC. So now we know that the out-of-reset requirement of the VPU is that the MERAM is powered on. This patch adds a workaround for A3RV to make sure A4LC is powered on - this so we can use the VPU even though the LCDCs are in blanking state and A4LC is supposed to be off.

2011-07-07ARM: 6993/1: platsmp: Allow secondary cpu hotplug with maxcpus=1Stephen Boyd
If an ARM system has multiple cpus in the same socket and the kernel is booted with maxcpus=1, secondary cpus are possible but not present due to how platform_smp_prepare_cpus() is called. Since most typical ARM processors don't actually support physical hotplug, initialize the present map to be equal to the possible map in generic ARM SMP code. Also, always call platform_smp_prepare_cpus() as long as max_cpus is non-zero (0 means no SMP) to allow platform code to do any SMP setup. After applying this patch it's possible to boot an ARM system with maxcpus=1 on the command line and then hotplug in secondary cpus via sysfs. This is more in line with how x86 does things.

2011-07-02PM / Domains: Rename struct dev_power_domain to struct dev_pm_domainRafael J. Wysocki
The naming convention used by commit 7538e3db6e015e890825fbd9f86599b (PM: Add support for device power domains), which introduced the struct dev_power_domain type for representing device power domains, evidently confuses some developers who tend to think that objects of this type must correspond to "power domains" as defined by hardware, which is not the case. Namely, at the kernel level, a struct dev_power_domain object can represent arbitrary set of devices that are mutually dependent power management-wise and need not belong to one hardware power domain. To avoid that confusion, rename struct dev_power_domain to struct dev_pm_domain and rename the related pointers in struct device and struct pm_clk_notifier_block from pwr_domain to pm_domain.

2011-06-29ARM: 6886/1: mmc, Add zboot from eSD support for SuperH Mobile ARMSimon Horman
This allows a ROM-able zImage to be written to eSD and for SuperH Mobile ARM to boot directly from the SDHI hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it.

This patch updates the board specific USB support code for the sh7372 Mackerel board. With this patch applied port CN22 is driven by the recently added renesas_usbhs driver using the first USB controller included in sh7372 aka USBHS0. Hotplugging of USBHS0 unfortunately has to be handled by software polling. The sh7372 SoC itself obviously supports hotplug notification by IRQ but on the Mackerel board this IRQ happens to be used for the touch screen.

2011-05-25ARM: mach-shmobile: mackerel: add renesas_usbhs support for USB1Kuninori Morimoto
renesas_usbhs driver can use external interrupt mode (which come from USB-PHY) or autonomy mode (it use own interrupt) for detecting connection/disconnection when Function. And it will be power OFF while it has been disconnecting if external interrupt mode is selected. mackerel board has 2 USB ports. But we can not use external interrupt mode on CN22 USB0 port which is only for USB Function. IRQ7-PORT40 is already used by Touchscreen, and USB-PHY needs IRQ7-PORT167. It is impossible to use IRQ7 demux on mackerel. We can use external interrupt mode USB-Function on "USB1". USB1 can become Host by r8a66597, and become Function by renesas_usbhs. But don't select both drivers in same time. These 2 drivers are not supporting IRQ SHARD.
