[ARM] 5460/1: Orion: reduce namespace pollution

2009-04-23T22:25:41+00:00

Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.

[WATCHDOG] omap_wdt.c: move probe function to .devinit.text

2009-04-08T06:21:57+00:00

A pointer to omap_wdt_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

[WATCHDOG] orion5x_wdt: Add shutdown callback, use watchdog ping function

2009-04-08T06:09:01+00:00

* Added a callback to disable the watchdog on shutdown.
* Use a separate ping function to reduce the number of register accesses
  if the watchdog is already enabled and just needs to be reloaded.
* Minor cleanup of function names.

[WATCHDOG] i6300esb.c: Restructure initialization of the device

2009-04-08T06:06:50+00:00

The i6300ESB watchdog should be stopped before userspace has access to the
watchdog. So fix this and restructure the initialization sequence into:
	* See if we have a i6300 device
	* make sure that we have valid module parameters
	* Initialize the device
	* register the /dev/watchdog device so that userspace has access

[WATCHDOG] i6300esb.c: Fix the GETSTATUS and GETBOOTSTATUS ioctls.

The WDIOC_GETSTATUS and WDIOC_GETBOOTSTATUS should return WDIOF_* flags

powerpc/wdrtas: Update wdrtas_get_interval to use rtas_data_buf

2009-04-07T05:07:43+00:00

The buffer passed to the ibm,get-system-parameter RTAS call must be
in the RMA.  To ensure we pass an address in the RMA use rtas_data_buf
for the actual RTAS call and then copy the result to value.  We can't
just make it static because this can be compiled in as a module.

Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the
function.
