caif-hsi: Make inactivity timeout configurable.

2011-10-19T07:25:42+00:00

CAIF HSI uses a timer for inactivity. Upon timeout HSI-wake signaling
is initiated to allow power-down of the HSI block.

caif-hsi: HSI-Platform device register and unregisters itself

2011-10-19T07:25:41+00:00

Platform device is no longer removed from caif_hsi at shutdown.
The HSI-platform device must do it's own registration and unregistration.

caif-hsi: Making read and writes asynchronous.

2011-10-19T07:25:41+00:00

Some platforms do not allow to put HSI block into low-power
mode when FIFO is not empty. The patch flushes (by reading)
FIFO at wake down sequence. Asynchronous read and write is
implemented for that. As a side effect this will also greatly
improve performance.

caif-hsi: Fix for wakeup condition problem

2011-10-19T07:25:41+00:00

Under stressed conditions a race could happen when del_timer_sync() was called
from softirq context at the same time when mod_timer_pending() for the same
timer was called from the workqueue. This leaded to a state mismatch in the
CAIF HSI driver and following unexpected link wakeup procedure.

The fix puts del_timer_sync() and mod_timer_pending() calls under a spin lock
to protect against the race condition.

caif-hsi: Fixing a race condition in the caif_hsi code

2011-10-19T07:25:41+00:00

cfhsi->tx_state was not protected by a spin lock. TX soft-irq could interrupt
cfhsi_tx_done_work work leading to inconsistent state of the driver.

caif-hsi: HSI Fix uninitialized data in HSI header

2011-10-19T07:25:40+00:00

CAIF HSI header may be uninitialized and cause last message to
be repeated if transmit size is ~86 bytes long.

caif: Remove OOM messages, use kzalloc

2011-08-28T21:16:13+00:00

Remove per site OOM messages because they duplicate
the generic mm subsystem OOM message.

Use kzalloc instead of kmalloc/memset
when next to the OOM message removals.

Reduces object size (allyesconfig ~2%)
