2008-02-14[POWERPC] Remove unused CONFIG_WANT_DEVICE_TREEGrant Likely
CONFIG_DEVICE_TREE was the only user of CONFIG_WANT_DEVICE_TREE but it was removed in commit id 25431333813686654907ab987fb5de10c10a16db (bootwrapper: Build multiple cuImages). This removes CONFIG_WANT_DEVICE_TREE from Kconfig and the defconfigs. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
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.

2008-01-26[POWERPC] Add common clock setting routine mpc52xx_psc_set_clkdiv()Grant Likely
PSC drivers should not access the CDM registers directly. Instead provide a common routine for setting the PSC clock parameters with the required locking. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2008-01-26[POWERPC] mpc5200: normalize compatible property bindingsGrant Likely
Update MPC5200 drivers to also look for compatible properties in the form "fsl,mpc5200-*" to better conform to open firmware generic names recommended practice as published here: http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html This patch should *not* break compatibility with older device trees which do not use the 'fsl,' prefix. The drivers will still bind against the older names also. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2008-01-26[POWERPC] mpc52xx: clean up KconfigGrant Likely

2008-01-18[POWERPC] mpc5200: Add generic support for simple MPC5200 based boardsMarian Balakowicz
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.

2008-01-18[POWERPC] mpc5200: eliminate mpc52xx_*_map_*() functions.Grant Likely
mpc5200 platform code defines a bunch of map functions which duplicate the functionality of of_iomap(). Remove them and use of_iomap() instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2008-01-18[POWERPC] mpc5200: Add common mpc52xx_setup_pci() routineMarian Balakowicz

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. This also adds the flag x86 already has to avoid ISA alignment on bridges that don't have ISA forwarding enabled (no legacy devices on the top level bus) and sets it for PowerMacs.

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> .

2007-10-10[POWERPC] MPC5200: Don't make firmware fixups into common codeGrant Likely
The Lite5200 u-boot image doesn't entirely configure the processor correctly and so Linux needs to fixup the cpu setup in setup_arch. Fixing the CPU setup is good, but making it into common code is not a good idea. New board ports should be encouraged not to take the lead of the lite5200 and instead get their firmware to setup the CPU the right way.

The Freescale and Marvell PCI controllers dont require explicit setting for type 1 config cycles. They handle producing them by implicitly looking at the bus, devfn. The TSI108 and 52xx don't use the generic PCI indirect code and thus don't bother with set_cfg_type. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
