serial: kill off uart_info

2009-09-19T20:13:28+00:00

We moved this into uart_state, now move the fields out of the separate
structure and kill it off.

serial: Make ucc_uart work in HW UART mode

2009-06-16T02:45:31+00:00

In HW UART mode the TxBD[READY] is not cleared by H/W (RISC engine) when
the user send characters to Tx buffer of QE UART.  So, these characters
stay on the QE forever, never go to UART line.

Merge branch 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

2008-10-20T20:23:01+00:00

This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.

The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]).  The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.

* 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (178 commits)
  genirq: improve include files
  intr_remapping: fix typo

  genirq: cleanup the sparseirq modifications
  genirq: remove artifacts from sparseirq removal
  genirq: revert dynarray

serial: fix driver_name conflicts

2008-06-06T18:29:09+00:00

Some drivers are using too generic "serial" name for driver_name, this
might cause issues, like this:

Freescale QUICC Engine UART device driver
proc_dir_entry 'serial' already registered

[cf82dff0] [c000fa74] kernel_thread+0x44/0x60

^^ The board is using ucc_uart.c and 8250.c, both registered as
   "serial".

This patch fixes two drivers that are using "serial" for driver_name and
not "ttyS" for dev_name.  Drivers that are using "ttyS" for dev_name, will
conflict anyway, so we don't bother with these.

[POWERPC] QE: UCC nodes cleanup

2008-04-17T06:01:38+00:00

- get rid of `model = "UCC"' in the ucc nodes
  It isn't used anywhere, so remove it. If we'll ever need something
  like this, we'll use compatible property instead.
- replace last occurrences of device-id with cell-index.
  Drivers are modified for backward compatibility's sake.
