      dt: remove of_alias_get_id() reference · 9e191b22
      Grant Likely authored 
      

of_alias_get_id() is broken and being reverted.  Remove the reference
to it and replace with a single incrementing id number.

There is no risk of regression here on the imx driver since the imx
change to use of_alias_get_id() is commit 22698aa2, "serial/imx: add
device tree probe support" which is new for v3.1, and it won't get
used unless CONFIG_OF is enabled and the board is booted using a
device tree.  A single incrementing integer is sufficient for now.

So out it goes as well.

The PORT_S3C2400 definition in include/linux/serial_core.h is left there
to prevent a reuse of the same number for another port type.

Commit bcae8aeb "[ARM] S3C24A0: Initial architecture support files"
brought in a bunch of files while explicitly leaving out the corresponding
Kconfig entry, stating that the series is not complete.

More than 2.5 years later, the support for this has not seen any progress.
This is therefore dead code.  If someone wants to revive this code, it is
always possible to retrieve it from the Git repository.

      serial: mrst_max3110: initialize waitqueue earlier · 33b1e693
      Mika Westerberg authored 
      

The driver went to initialize its waitqueue at the start of the main
processing thread.  However, it is possible that this thread is not
scheduled on a CPU before the write function is called which leads to a
following error:

Fix this by initializing the waitqueue before the main thread is

      net: remove mm.h inclusion from netdevice.h · b7f080cf
      Alexey Dobriyan authored 
      

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.

For all ports with a valid SCLSR register we can use the generic FIFO
overrun detection logic. Test the validity of the SCLSR register rather
than depending explicitly on port type, which can be ambiguous for the
SCIFA/B types.

      serial: sh-sci: FIFO sizing helper consolidation. · 72b294cf
      Paul Mundt authored 
      

This consolidates all of the TX/RX fill/room nonsense in to a single set
of fairly heavyweight definitions. The implementation goes in descending
order of complexity, testing the register map for capabilities until we
run out of options and do it the legacy SCI way. Masks are derived
directly from the per-port FIFO size, meaning that platforms with FIFO
sizes not matching the standard port types will still need to manually
fix them up.

This also fixes up a number of issues such as tx_empty being completely
bogus for SCI and IrDA ports, some ports using masks smaller or greater
than their FIFO size, and so forth.

      serial: sh-sci: Abstract register maps. · 61a6976b
      Paul Mundt authored 
      

This takes a bit of a sledgehammer to the horribly CPU subtype
ifdef-ridden header and abstracts all of the different register layouts
in to distinct types which in turn can be overriden on a per-port basis,
or permitted to default to the map matching the port type at probe time.

In the process this ultimately fixes up inumerable bugs with mismatches
on various CPU types (particularly the legacy ones that were obviously
broken years ago and no one noticed) and provides a more tightly coupled
and consolidated platform for extending and implementing generic
features.
