[POWERPC] Add common clock setting routine mpc52xx_psc_set_clkdiv()

2008-01-26T22:32:18+00:00

PSC drivers should not access the CDM registers directly.  Instead provide
a common routine for setting the PSC clock parameters with the required
locking.

[POWERPC] mpc5200: eliminate mpc52xx__map_() functions.

2008-01-18T16:30:37+00:00

mpc5200 platform code defines a bunch of map functions which duplicate the
functionality of of_iomap().  Remove them and use of_iomap() instead.

[POWERPC] mpc5200: Add common mpc52xx_setup_pci() routine

2008-01-18T16:30:07+00:00

This patch moves a generic pci init code from lite5200
platform file to a common mpc52xx_setup_pci() routine
and adds additional compatibility property verification.

[POWERPC] Add mpc52xx_find_and_map_path(), refactor utility functions

2007-10-21T18:42:47+00:00

Add helper routine mpc52xx_find_and_map_path(). Extract common code to
mpc52xx_map_node() and refactor mpc52xx_find_and_map().

[POWERPC] bestcomm: Restrict bus prefetch bugfix to original mpc5200 silicon.

2007-10-21T16:52:02+00:00

Only the MPC5200 needs this bug fix.  MPC5200B is okay.

PM: Rework struct platform_suspend_ops

2007-10-18T21:37:18+00:00

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.

[POWERPC] MPC5200: Don't make firmware fixups into common code

2007-10-10T16:22:04+00:00

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.

[POWERPC] MPC5200 low power mode

2007-09-19T05:25:34+00:00

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.

[POWERPC] mpc52xx suspend to deep-sleep

2007-05-07T10:31:15+00:00

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.
