drivers/serial/uartlite.c: Add missing of_node_put

2007-12-11T03:43:55+00:00

There should be an of_node_put when breaking out of a loop that iterates
using for_each_compatible_node.

This was detected and fixed using the following semantic patch.
(http://www.emn.fr/x-info/coccinelle/)

//

identifier d;
type T;
expression e;
iterator for_each_compatible_node;

T *d;
...
for_each_compatible_node(d,...)
  {... when != of_node_put(d)
       when != e = d
(
   return d;
|
+  of_node_put(d);
?  return ...;
)
...}

[POWERPC] Uartlite: speed up console output

2007-11-01T12:12:19+00:00

Change the wait_tx routine to call cpu_relax() instead of udelay() to
reduce console output latency and test for the TXFULL bit instead of
TXEMPTY.  That way the FIFO doesn't need to by 100% flushed before
writing the next character.

[POWERPC] Uartlite: Revert register io access changes

2007-10-03T12:37:41+00:00

Reverts commit a15da8eff3627b8368db7f5dd260e5643213d918

This driver is used by devices other than the xilinx opb-uartlite which
depend on bytewise access to the registers.  The change to 32 bit access
does not work on these devices.

[POWERPC] Uartlite: Let the console be initialized earlier

2007-10-03T12:23:16+00:00

By configuring it earlier we get console output sooner which is helpful
for debugging when the kernel crashes before the serial drivers are
initialized.

[POWERPC] Uartlite: Comment block tidy

2007-10-03T12:23:15+00:00

Tidy the comments to split the driver into logical section; the main driver,
the console driver, the platform bus binding, and module initialization
and teardown.

[POWERPC] Uartlite: Fix reg io to access documented register size

2007-10-03T12:23:14+00:00

The Uartlite data sheet defines the registers as 32 bit wide.  This
patch changes the register access to use 32 bit transfers and eliminates
the magic +3 offset which is currently required to make the device
work.
