net: remove mm.h inclusion from netdevice.h

2011-06-22T02:17:20+00:00

Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

Serial: ifx6x60c: Remove duplicate includes of linux/tty.h

2011-04-19T23:33:37+00:00

Including linux/tty.h 3 times is a little over the top - once will do.

tiocmset: kill the file pointer argument

2011-02-17T19:52:43+00:00

Doing tiocmget was such fun we should do tiocmset as well for the same
reasons

tiocmget: kill off the passing of the struct file

2011-02-17T19:47:33+00:00

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

serial: ifx6x60: probe routine needs to call spi_setup

2011-02-17T19:16:15+00:00

The probe routine should call spi_setup() to configure
the SPI bus so it can properly communicate with the device.
E.g. the device operates in SPI mode 1.

Called spi_setup to configure SPI mode, max_speed_hz, and bpw

serial: ifx6x60: set SPI max_speed_hz based on platform type

2011-02-17T19:16:14+00:00

Platforms containing the 6260 can run up to 25Mhz.

For these platforms set max_speed_hz to 25Mhz.

serial: ifx6x60: changed internal bpw from boolean to int

2011-02-17T19:16:14+00:00

driver should support 32bit SPI transfers. The boolean variable
only allowed 8/16.

Changed to support 8/16/32 for future enabling
of 32 bpw.

serial: ifx6x60: dma_alloc_coherent must use parent dev

2011-02-17T19:16:14+00:00

This driver is a SPI protocol driver and has no DMA ops
associated with the device so the call will fail. Furthermore,
the DMA allocation made here will be used by the SPI
controller driver (parent dev) so it makes sense to
pass that device instead.

The port ops must be set AFTER calling port init as that function
zeroes the structure
