POWERPC: drivers: remove __dev* attributes.

2013-01-03T23:57:04+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

powerpc/85xx: Add lbc suspend support for PM

2011-11-24T08:01:40+00:00

Power supply for LBC registers is off when system go to deep-sleep state.
We save the values of registers before suspend and restore to registers
after resume.

We removed the last two reservation arrays from struct fsl_lbc_regs for
allocating less memory and minimizing the memcpy size.

powerpc/fsl-lbc: Fix for fsl_upm

2011-11-24T08:00:42+00:00

If Freescale LBC driver fails to initialise itself from device tree, then
internal structure is freed only but not NULL-fied.  As result functions
fsl_lbc_find() after checking the structure is not NULL are trying to
access device registers.

powerpc: various straight conversions from module.h --> export.h

2011-10-31T23:30:44+00:00

All these files were including module.h just for the basic
EXPORT_SYMBOL infrastructure.  We can shift them off to the
export.h header which is a way smaller footprint and thus
realize some compile time gains.

powerpc: Fix up implicit sched.h users

2011-10-31T23:30:40+00:00

They are getting it through device.h --> module.h path, but we want
to clean that up.  This is a sample of what will happen if we don't:

Add in sched.h so these get the definitions they are looking for.

Simultaneous FCM and GPCM or UPM operation may erroneously trigger
bus monitor timeout.

Set the local bus monitor timeout value to the maximum by setting
LBCR[BMT] = 0 and LBCR[BMTPS] = 0xF.

P4080/mtd: Fix the freescale lbc issue with 36bit mode

2010-10-25T14:41:04+00:00

When system uses 36bit physical address, res.start is 36bit
physical address. But the function of in_be32 returns 32bit
physical address. Then both of them compared each other is
wrong. So by converting the address of res.start into
the right format fixes this issue.

P4080/eLBC: Make Freescale elbc interrupt common to elbc devices

2010-10-25T14:40:54+00:00

Move Freescale elbc interrupt from nand driver to elbc driver.
Then all elbc devices can use the interrupt instead of ONLY nand.

For former nand driver, it had the two functions:

1. detecting nand flash partitions;
2. registering elbc interrupt.

Now, second function is removed to fsl_lbc.c.
