2011-06-14ARM: mach-shmobile: Mackerel USB platform data updateMagnus Damm
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. Also fix the pinmux configuration to avoid setting up unused pins and fix minor spelling errors. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

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.

2011-05-24ARM: arch-shmobile: Use multiple irq vectors for SDHISimon Horman
This patch reverts "ARM: mach-shmobile: sh7372 SDHI vector merge" and supplies 3 IRQ resources for each SDHI block. Some blocks have a 4th IRQ, but this is used for DRM feathres that I do not have access tot he documentation for and are almost certainly tainted by licensing issues. So the 4th IRQ is not hooked-up even if it exists.

2011-05-24ARM: mach-shmobile: Disable sh7372 RT side MSTP bitsMagnus Damm
Update the sh7372 clock code to set the RT side set of MSTP bits to a fixed disabled state. The sh7372 SoC contains two sets of MSTP bits, one for the ARM (SYS) side, and one for the SH4AL-DSP (RT) side. The actual clock associated with the MSTP bit will only be stopped when both sides have set the MSTP bit to disabled mode. Some MSTP bits are enabled by default after hardware reset, so this patch adjusts the code to disable all MSTP bits associated with the RT side to allow the SYS side to have full control.

2011-04-30PM / Runtime: Generic clock manipulation rountines for runtime PM (v6)Rafael J. Wysocki
Many different platforms and subsystems may want to disable device clocks during suspend and enable them during resume which is going to be done in a very similar way in all those cases. For this reason, provide generic routines for the manipulation of device clocks during suspend and resume. Convert the ARM shmobile platform to using the new routines. Signed-off-by: Rafael J.

2011-04-29PM / Runtime: Add subsystem data field to struct dev_pm_infoRafael J. Wysocki

Convert the ARM shmobile platform to using the new field. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-04-29shmobile: Use power domains for platform runtime PMRafael J. Wysocki
shmobile platforms replace the runtime PM callbacks of the platform bus type with their own routines, but this means that the callbacks are replaced system-wide. This may not be the right approach if the platform devices on the system are not of the same type (e.g. some of them belong to an SoC and the others are located in separate chips), because in those cases they may require different handling. Thus it is better to use power domains to override the platform bus type's PM handling, as it generally is possible to use different power domains for devices with different PM requirements. Define a default power domain for shmobile in both the SH and ARM falvors and use it to override the platform bus type's PM callbacks. Since the suspend and hibernate callbacks of the new "default" power domains need to be the same and the platform bus type's suspend and hibernate callbacks for the time being, export those callbacks so that can be used outside of the platform bus type code.
