ASIC3 driver

2008-02-07T16:42:23+00:00

This is a patch for the Compaq ASIC3 multi function chip, found in many
PDAs (iPAQs, HTCs...).

It is a simplified version of Paul Sokolovsky's first proposal [1].  With
this code, it is basically a GPIO and IRQ expander.  My plan is to add more
features once this patch gets reviewed and accepted.

MCP_UCB1200: Convert from class_device to device

2008-01-25T04:40:06+00:00

struct class_device is going away, this converts the code to use struct
device instead.

typo fixes

2007-10-19T23:34:40+00:00

Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.

Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.

some kmalloc/memset ->kzalloc (tree wide)

2007-07-19T17:04:50+00:00

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

this transformation:

Freezer: make kernel threads nonfreezable by default

2007-07-17T17:23:02+00:00

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves.  This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.

It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.

The patch causes all kernel threads to be nonfreezable by default (ie.  to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear.  Additionally, it updates documentation to
describe the freezing of tasks more accurately.

SM501: Check SM501 ID register on initialisation

When binding the driver, check the ID register for a valid identity, in case

SM501: Clock updates and checks

2007-06-24T15:59:11+00:00

Ensure that the M1XCLK and MCLK are sourced from the same PLL (and refuse to
bind the driver if they are not).

Update the PCI to safe initialisation values, as 72MHz is the maximum clock
for 33MHz PCI bus mastering.

SM501: Fix sm501_init_reg() mask/set order

2007-06-24T15:59:11+00:00

The order of the set and mask operation in sm501_init_reg() was setting and
then masking the bits set.  Correct the order so that we do not end up with
288MHz SDRAM clocks on certain systems.
