omap-serial: Allow IXON and IXOFF to be disabled.

2011-08-23T17:58:38+00:00

Fixes logic bug that software flow control cannot be disabled, because
serial_omap_configure_xonxoff() is not called if both IXON and IXOFF bits
are cleared.

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36+00:00

Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.

serial: omap-serial: Enable the UART wake-up bits always

2011-02-03T22:10:22+00:00

OMAP can do also dynamic idling so wake-up enable register should be set
also while system is running. If UART_OMAP_WER is not set, then for instance
the RX activity cannot wake up the UART port that is sleeping.

This RX wake-up feature was working when the 8250 driver was used instead
of omap-serial. Reason for this is that the 8250 doesn't set the
UART_OMAP_WER and then arch/arm/mach-omap2/pm34xx.c ends up saving and
restoring the reset default which is the same than value
OMAP_UART_WER_MOD_WKUP here.

Fix this by moving the conditional UART_OMAP_WER write from serial_omap_pm
into serial_omap_startup where wake-up bits are set unconditionally.

OMAP: Enable Magic SysRq on serial console ttyOx

2011-02-03T19:43:11+00:00

Magic SysRq key is not working for OMAP on new serial
console ttyOx because SUPPORT_SYSRQ is not defined
for omap-serial.

This patch defines SUPPORT_SYSRQ in omap-serial and
enables handling of Magic SysRq character.

Further there is an issue of losing first break character.
Removing the reset of the lsr_break_flag fixes this issue.

tty: move drivers/serial/ to drivers/tty/serial/

2011-01-13T20:10:18+00:00

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.

This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
