2009-09-19serial: 8250: add IRQ trigger supportVikram Pandita1-0/+1
There is currently no provision for passing IRQ trigger flags for serial IRQs with triggering requirements (such as GPIO IRQs) This patch adds irqflags to plat_serial8250_port that can be passed from board file to reqest_irq() of 8250 driver Changes are backward compatible with boards passing UPF_SHARE_IRQ flag Tested on Zoom2 board that has IRQF_TRIGGER_RISING requirement for 8250 irq [Moved new flag to end to fix bugs in the original with the old_serial array -- Alan] Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-09-028250: improve workaround for UARTs that don't re-assert THRE correctlyWill Newton1-0/+1
Recent changes to tighten the check for UARTs that don't correctly re-assert THRE (01c194d9278efc15d4785ff205643e9c0bdcef53: "serial 8250: tighten test for using backup timer") caused problems when such a UART was opened for the second time - the bug could only successfully be detected at first initialization. For users of this version of this particular UART IP it is fatal. This patch stores the information about the bug in the bugs field of the port structure when the port is first started up so subsequent opens can check this bit even if the test for the bug fails. David Brownell: "My own exposure to this is that the UART on DaVinci hardware, which TI allegedly derived from its original 16550 logic, has periodically gone from working to unusable with the mainline 8250.c ... and back and forth a bunch. Currently it's "unusable", a regression from some previous versions. With this patch from Will, it's usable."

2008-07-20drivers/serial/: remove CVS keywordsAdrian Bunk1-2/+0
This patch removes CVS keywords that weren't updated for a long time in comments, printk's and MODULE_DESCRIPTION's (no printk's or MODULE_DESCRIPTION's are completely removed). While doing this I also found and fixed a missing \n in a printk in m32r_sio.c Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-05-318250 Serial Driver: revert extra IRQ flag definition patchBryan Wu1-5/+0
As Russell pointed out, original patch will break some serial configurations because of the dependency of the <asm/serial.h> header file.

2008-05-178250 Serial Driver: Added support for 8250-class UARTs in HV Sistemas H8606 boardJavier Herrero1-0/+5
Added support for 8250-class UARTs in HV Sistemas H8606 board, modification in 8250.c driver for correct compilation with Blackfin Besides, I think that there is more people using 8250-class UARTs with a different hardware than the H8606 board. This code can be shared by them. Signed-off-by: Javier Herrero <jherrero@hvsistemas.es> Acked-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Bryan Wu <cooloney@kernel.org>

The Mobility 16550A serial ports don't behave the same as standard 16550A ports, and need a helping hand to get them going once the transmitter has drained and been disabled. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-06-23[PATCH] Serial: Convert 8250 revision-based bug fixes to bug bitmaskRussell King1-0/+2
For some 8250 port types, we used to check the type of the port, and then determine whether the chip revision means the device is buggy. Instead, introduce a bit array, and set the appropriate bit(s) when we discover a buggy device. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+87
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
