staging: ozwpan: High resolution timers

Current implementation assumes HZ = 1000 for calculating
all internal timer intervals, which creates problem on
platforms where HZ != 1000.

As well we need resolution of less than 10 mSec for heartbeat
calculation, this creates problem on some platforms where HZ is
configured as HZ = 100, or around, which restricts us to timer interval
of 10 mSec. This is particularly found on embedded devices.

This patch moves on to use high resolution timers to calculate
all timer intervals as it allows us to have very small resolution
of timer interval, removing dependency on HZ.

11 years agostaging: comedi: das16: fix DMA init during board attach
H Hartley Sweeten [Mon, 29 Jul 2013 20:48:38 +0000 (13:48 -0700)]
staging: comedi: das16: fix DMA init during board attach

DMA support is optional in this driver. To enable it, the user
passes the desired DMA channel during the board attach. A timer
is then used by the driver to periodically get the analog input
data from the DMA.

Since the DMA support is optional, modify the init code so that
it only fails if the DMA channel is unavailable or the DMA buffers
can not be allocated. Don't fail just because the user passed an
invalid DMA channel (only DMA channels 1 and 3 are valid).

Remove the printk() noise about the DMA. Change the printk() when
the request_dma() fails into a dev_err().

Move the timer initialization so it's only setup if DMA is available.
It's not needed otherwise. Also, only hook up the subdevice command
support functions if DMA is available. This allows removing a couple
sanity checks in the command support.
