Currently misc_register() throws away the return from
class_simple_device_add(). This makes it impossible to get to the
class_device of the directories in /sys/class/misc and, for example,
thus impossible to add attributes to those directories.
Attached patch adds a class_device structure to the miscdevice structure
and assigns to it the value returned from class_simple_device_add() in
misc_register(), thus caching the value and allowing us to f.e. later
call class_device_create_file().
We need this for inotify, but I can see plenty of other misc. devices
wanting this and consider it missing but required functionality.
Add the class_device structure to miscdevice so that we can add sysfs
attributes to /sys/class/misc/foo

SGI has been using this driver under Linux since 2001 but it was
never included in the upstream kernel. SuSE did include the patch for mmtimer
in SLES 9. The driver has been widely used for applications on the Altix
platform.
The timer hardware was designed around the multimedia timer specification by
Intel but to my knowledge only SGI has implemented that standard. The driver
was written by Jesse Barnes.
The second revision has interrupt support removed and was somewhat simplified
by removing one include file.

I eliminated the request_irq brain damage, chopped off procfs support
(didn't care for it too much in the first place and it was adopted from
rtc.c), made the check for FMODE_WRITE in hpet_open and responded to a few
other suggestions.

The driver supports the High Precision Event Timer. The driver has adopted
a similar API to the Real Time Clock driver. It can support any number of
HPET devices and the maximum number of timers per HPET device. For further
information look at the documentation in the patch.
Thanks to Venki at Intel for testing the driver on X86 hardware with HPET.
HPET documentation is available at http://www.intel.com/design/chipsets/datashts/252516.htm

From: Paul Mundt <lethal@linux-sh.org>
This is the rest of the sh update, which includes everything else
sh-specific, general cleanups, bugfixes, etc. Nothing really eventful.

This adds class/misc/ for all misc devices (ones that use the
misc_register() function).
|

From: Christoph Hellwig <hch@lst.de>
keeping init order the same..
|
|
Use list macros for misc_device list.

|
From: Rusty Russell <rusty@rustcorp.com.au>
Previously, default aliases were hardwired into modutils. Now they should
be inside the modules, using MODULE_ALIAS() (they will be overridden by any
user alias).
|
|
Now that devfs_handle_t is gone from all structs there is no
reason to include it in headers.
Fix the fallout by including previously implicit headers and fixing
the drivers that didn't include devfs_fs_kernel.h explicitly.

This doesn't mean dmapi is scheduled for inclusion, just adding
the reserved minor number to miscdevice.h for documentation purposes.

M68k input drivers cleanup:
- Remove remnants from the old input layer:
o Config.help entries for the Amiga and Atari mouse drivers
o Apollo keyboard code (including beep support)
o Dummy keyboard initialization, keyboard repeat, and keyboard LEDs code
for MVME147, Sun-3, Sun-3x,
o Makefile entries for Atari keyboard, mouse and joystick drivers, and
the HP300 Human Interface Loop driver
o kbd-reset kernel command line parameters
o defconfig entry for the Amiga mouse driver
o Mac ADB mouse driver glue
o Amiga and Mac ADB mouse driver minors
- Always include new input layer configuration data
