powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

cpm2: Rework baud rate generators configuration to support external clocks.

2008-07-28T13:47:45+00:00

The CPM2 BRG setup functions cpm_setbrg and cpm2_fastbrg don't support
external clocks. This patch adds a new exported __cpm2_setbrg function
that takes the clock rate and clock source as extra parameters, and moves
cpm_setbrg and cpm2_fastbrg to include/asm-powerpc/cpm2.h where they
become inline wrappers around __cpm2_setbrg.

powerpc/cpm: Remove !CONFIG_PPC_CPM_NEW_BINDING code

2008-06-26T06:49:06+00:00

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so
we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING.

[POWERPC] CPM: Move definition of buffer descriptor to cpm.h

2008-01-28T14:31:06+00:00

Buffer descriptors are used by both CPM1 and CPM2. Move the definitions
from the cpm dependent include file to common cpm.h

[POWERPC] 85xx: Killed

2007-10-11T14:14:31+00:00

asm-powerpc/mpc85xx.h was really a hold over from arch/ppc.  Now that
more decoupling has occurred we can remove  and some of
its legacy.

As part of this we moved the definition of CPM_MAP_ADDR into cpm2.h
for 85xx platforms.  This is a stop gap until drivers stop using
CPM_MAP_ADDR.

[POWERPC] cpm: Describe multi-user ram in its own device node.

2007-10-04T20:47:05+00:00

The way the current CPM binding describes available multi-user (a.k.a.
dual-ported) RAM doesn't work well when there are multiple free regions,
and it doesn't work at all if the region doesn't begin at the start of
the muram area (as the hardware needs to be programmed with offsets into
this area).  The latter situation can happen with SMC UARTs on CPM2, as its
parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
support moving it.

It is now described with a muram node, similar to QE.  The current CPM
binding is sufficiently recent (i.e. never appeared in an official release)
that compatibility with existing device trees is not an issue.

The code supporting the new binding is shared between cpm1 and cpm2, rather
than remain separated.  QE should be able to use this code as well, once
minor fixes are made to its device trees.

[POWERPC] cpm2: Add cpm2_set_pin().

2007-10-04T16:02:18+00:00

This provides a generic way for board code to set up CPM pins, rather
than directly poking magic values into registers.

[POWERPC] cpm2: Infrastructure code cleanup.

2007-10-04T16:02:04+00:00

Mostly sparse fixes (__iomem annotations, etc); also, cpm2_immr
is used rather than creating many temporary mappings.
