2008-07-25gpiolib: allow user-selectionMichael Buesch
This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

2008-07-16powerpc: pci config cleanupJohn Rigby
Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes.

2008-07-12powerpc/mpc5200: PCI write combine timerAndre Schwarz
On MPC5200 the PCI target control register (PCITCR) @ MBAR + 0xD6C is initialized with only bit 7 (Latrule disable) set. The 8-Bit write combine timer (Bits 24..31) should be also set to a reasonable value _greater zero_ (0x08 = default) since setting it to 0x00 leads to _very poor_ performance as a PCI target since external burst won't be possible at all. Setting the WCT to 0x08 (cache-line size) leads to good overall perfomance. Signed-off-by: Andre Schwarz <andre.schwarz@matrix-vision.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2008-07-01powerpc/mpc5200: Fix lite5200b suspend/resumeTim Yamin
Suspend/resume ("echo mem > /sys/power/state") does not work with vanilla kernels -- the system does not suspend correctly and just hangs. This patch fixes this so suspend/resume works: 1) of_iomap does not map the whole 0xC000 of the MPC5200 immr so saving registers does not work. 2) PCI registers need to be saved and restored.

2008-02-01Suspend: Introduce begin() and end() callbacksRafael J. Wysocki
On ACPI systems the target state set by acpi_pm_set_target() is reset by acpi_pm_finish(), but that need not be called if the suspend fails.  All platforms that use the .set_target() global suspend callback are affected by analogous issues. For this reason, we need an additional global suspend callback that will reset the target state regardless of whether or not the suspend is successful.  Also, it is reasonable to rename the .set_target() callback, since it will be used for a different purpose on ACPI systems (due to ACPI 1.0x code ordering requirements). Introduce the global suspend callback .end() to be executed at the end of the suspend sequence and rename the .set_target() global suspend callback to .begin(). Signed-off-by: Rafael J.

This patch adds support for 'mpc5200-simple-platform' compatible boards which do not need a platform specific setup. Such boards are supported assuming the following: - GPIO pins are configured by the firmware, - CDM configuration (clocking) is setup correctly by firmware, - if the 'fsl,has-wdt' property is present in one of the gpt nodes, then it is safe to use such gpt to reset the board, - PCI is supported if enabled in the kernel configuration and if there is a PCI bus node defined in the device tree.

2007-12-20[POWERPC] pci32: Add flags modifying the PCI code behaviourBenjamin Herrenschmidt
This adds to the 32 bits PCI code some flags, replacing the old pci_assign_all_busses global, that allow us to control various aspects of the PCI probing, such as whether to re-assign all resources or not, or to not try to assign anything at all.

2007-10-18PM: Rework struct platform_suspend_opsRafael J. Wysocki
There is no reason why the .prepare() and .finish() methods in 'struct platform_suspend_ops' should take any arguments, since architectures don't use these methods' argument in any practically meaningful way (ie. either the target system sleep state is conveyed to the platform by .set_target(), or there is only one suspend state supported and it is indicated to the PM core by .valid(), or .prepare() and .finish() aren't defined at all).  There also is no reason why .finish() should return any result.

2007-10-18PM: Rename struct pm_ops and related thingsRafael J. Wysocki
The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend.  Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'.  In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly.

2007-10-18PM: Move definition of struct pm_ops to suspend.hRafael J. Wysocki
Move the definition of 'struct pm_ops' and related functions from <linux/pm.h> to <linux/suspend.h> . There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .
