serial: sh-sci: using correct fifo size for SCIF and SCIFA ports.

2010-01-14T23:33:20+00:00

The sh-sci driver used the wrong fifosize for PORT_SCIFA and PORT_SCIF
ports. If an incorrect size is used, the serial core will enforce an
early shutdown on the port, especially with baudrates < 9600.

serial: sh-sci: Convert tremaining ctrl_xxx I/O routines to __raw_xxx.

2009-12-24T05:52:43+00:00

ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard
API that accomplishes the same thing. As such, this converts the
remaining sh-sci straggles over, which enables the driver to be wired up
for ARM SH-Mobile CPUs as well.

serial: sh-sci: earlyprintk zero uartclk fix

2009-12-24T05:50:55+00:00

This establishes a sensible max baud rate for the earlyprintk cases where
the port's uartclk has not yet been determined.

sh-sci: Extend sh-sci driver with early console V2

2009-12-15T03:06:29+00:00

This is V2 of early serial console support for the sh-sci
driver. The early serial console is using early platform
devices and "earlyprintk". To use this feature the early
platform devices must be broken out to one device per port
and the desired port should be selected on the kernel command
line like: "earlyprintk=sh-sci.N[,baudrate][,keep]"

serial: sh-sci: Fix too early port disabling.

2009-12-04T04:42:23+00:00

Currently serial ports on SH CPUs get disabled too early, because the
sci_tx_empty() routine claims to not be able to detect whether the
transmission has been completed and just always returns TIOCSER_TEMT. This
results in corrupt output of last characters if the port is not open for
reading at the same time. It is however possible to detect whether
transmission has been completed. Use the TEND bit of the status register
for this.

serial: sh-sci: Depend on HAVE_CLK unconditionally.

2009-11-25T07:23:35+00:00

The sh-sci code conditionalized the clock framework support in order to
give the other platforms a chance to catch up. sh64 supported this some
time ago and the forthcoming ARM changes handle this as well, this leaves
h8300 as the odd one out. H8300 has had since 2.5 to merge it's sh-sci
support upstream, and has yet to do so. At this point I will no longer be
holding back the driver to support an unreponsive architecture, 7 years
is quite enough of a grace period. Support is easily implemented on the
architecture if and when it ever decides to merge its changes upstream.

serial: sh-sci: don't use __devexit_p to wrap sci_remove

2009-11-25T01:39:43+00:00

The function sci_remove is defined without any section modifier, so
don't use __devexit_p to wrap it.
