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.

2007-10-10[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.

2007-09-19[POWERPC] MPC5200 low power modeDomen Puncer
Low-power mode implementation for Lite5200b. Some I/O registers are also saved here. A recent U-Boot that supports this (lite5200b_PM_config) is needed.

2007-05-07[POWERPC] mpc52xx suspend to deep-sleepDomen Puncer
Implement deep-sleep on MPC52xx. SDRAM is put into self-refresh with help of SRAM code (alternatives would be code in FLASH, I-cache). Interrupt code must also not be in SDRAM, so put it in I-cache. MPC52xx core is static, so contents will remain intact even with clocks turned off.

2007-01-09[POWERPC] 52xx: Don't use device_initcall to probe of_platform_busSylvain Munaut
Using device_initcall makes it happen for every platform that compiles this file in. This is really bad, for obvious reasons. Instead, we use the .init field of the machine description. If the platform needs the hook to do something specific it can provides its own function and call mpc52xx_declare_of_platform_devices from there. If not, the mpc52xx_declare_of_platform_devices function can directly be used as the init hook.

2006-12-04[POWERPC] Add common routines for 52xx support in arch/powerpcGrant Likely
Adds utility routines used by 52xx device drivers and board support code. Main functionality is to add device nodes to the of_platform_bus, retrieve the IPB bus frequency, and find+ioremap device registers.

2006-11-13[PATCH] Add MPC5200 Interrupt Controller support.Nicolas DET
This adds support for the MPC52xx Interrupt controller for ARCH=powerpc. It includes the main code in arch/powerpc/sysdev/ as well as a header file in include/asm-powerpc.
